Mesenteric cysts in Nigerians.

Mesenteric cysts are uncommon and are said to be rarer among blacks than in caucasians. We report six mesenteric cysts seen in five patients over a 9 1/2 year period with an incidence of one in 48,497 hospital admissions. there were three males and two females. Ultrasonography was carried out in three of our five cases. There is need to include mesenteric cyst in the differential diagnosis of an abdominal mass. Surgery was the mainstay of treatment. At laparotomy, five of the cysts were found in the mesentery of the small bowel. Simple enucleation was done in one patient while cyst resection with adjacent bowel was carried out in three patients. There were two cysts in the youngest patient and these were internally drained. All the patients did well with uneventful post-operative period with no mortality. Follow up had been from 14 months to 6 years.

Mesenteric cysts in children.

BACKGROUND: Mesenteric cysts are uncommon benign abdominal masses. Approximately one third of patients with these lesions are children. METHODS: We reviewed our clinical records for the past 14 years (corresponding to the period of time in which ultrasonography and computed tomography became reliable methods for imaging pediatric patients) and found 10 patients with mesenteric cysts. RESULTS: We were surprised to discover that abdominal pain was a presenting complaint in all but one patient. Five of the patients had the findings of an acute surgical abdomen and were thought to have appendicitis. Two patients operated on for appendicitis were transferred to our hospital with the diagnosis of an abdominal mass. In each case the mass was a mesenteric cyst. Cyst distribution included the small-bowel mesentery in seven patients, the transverse mesocolon in two patients, and the right mesocolon in one patient. Six cases required concomitant bowel resection for the cyst removal, and all were cystic lymphangiomas. The resected specimens were described as cystic lymphangiomas in eight of the 10 cases. CONCLUSIONS: Mesenteric cysts should be considered as an origin for abdominal pain in children, particularly after exclusion of more common diagnoses. We have found ultrasonographic imaging to be a reliable method for the diagnosis of appendicitis in children and advocate its use as an initial imaging study in patients with an acute surgical abdomen and presumed appendicitis. If appendicitis is indicated unlikely by ultrasonogram, the examination can be extended to the remainder of the abdomen, which can reveal mesenteric cysts or other pathologic conditions.

[Appearance forms of mesenteric cyst. A case report].

Mesenteric cysts are considered as a rare cause of abdominal complaints. Histologically, several specific types can be distinguished: lymphangioma, nonpancreatic pseudocyst, enteric duplication cyst, enteric cyst and mesothelial cyst. Histopathological classification and radiological findings in two cases of mesenteric cysts are presented, and, with regard to the literature, radiological appearance and differential diagnoses are discussed.

Peritonitis caused by a ruptured, infected mesenteric cyst initially interpreted as an ovarian cyst. A case report.

BACKGROUND: Mesenteric cysts are rare intraabdominal lesions of childhood that may vary in presentation from an asymptomatic mass to an acute abdomen. CASE: We encountered a rare case of peritonitis caused by a ruptured, infected mesenteric cyst of the mesocolon in a female child that had been initially interpreted as a ruptured ovarian cyst. CONCLUSION: When confronted with a large unilocular or septated echolucent mass in the lower abdomen in female children, gynecologists should consider a mesenteric cyst in the differential diagnosis.

Mesenteric cysts. Toward less confusion?

OBJECTIVE: Mesenteric cysts are rare intra-abdominal masses generally omited or briefly reported in textbooks. Their rarity had fostered a lack of information and difficulty in classification. The goal of the study is to present a simple, comprehensive, and reproducible classification of mesenteric cysts. METHODS: A large review of the literature with particular attention to recent series was performed in order to identify and characterize the different groups of mesenteric cysts. RESULTS: Although cysts of lymphatic and mesothelial origin are those most frequently encountered, they were confounded or omitted in previous classifications. However, their distinction is important because their incidence and mode of presentation differ. Lymphangiomas predominate in male children, may cause acute abdominal pain, and frequently require resection of adjacent structures. In contrast, cysts of mesothelial origin such as benign cystic mesothelioma are seen more frequently in young and middle-aged women, usually present with more indolent symptoms, and often recurs. CONCLUSIONS: A new classification based essentially on histopathological features should include the 6 following groups: (1) cysts of lymphatic origin (simple lymphatic cyst and lymphangioma); (2) cysts of mesothelial origin (simple mesothelial cyst, benign cystic mesothelioma, and malignant cystic mesothelioma); (3) cysts of enteric origin (enteric cyst and enteric duplication cyst); (4) cysts of urogenital origin; (5) mature cystic teratoma (dermoid cysts), and (6) pseudocysts (infectious and traumatic cysts).

Mesenteric cysts in pregnancy. A case report.

Mesenteric cysts are rare. These large, often asymptomatic growths may be misinterpreted easily by the clinician as representing either benign or malignant ovarian tumors, renal masses, or hepatic tumors or cysts. We treated a women for a mesenteric cyst complicating her second pregnancy. Because of the increasing use of ultrasound in a wide variety of pregnancy complications, and because of the mesenteric cysts's unique sonographic appearance (resembling that of a benign ovarian tumor), such a cyst must be included in the differential diagnosis of large, cystic abdominal masses in pregnancy.

[Intraabdominal cystic lesions - the differentation of mesenteric cysts and cystic lymphangioma].

Mesenteric cysts and cystic lymphangioma are rare intraabdominal lesions. In our clinic, during one year, two young women with these intraabdominal cysts underwent operation because of unspecific abdominal pain. Despite preoperative imaging the final diagnosis of a cystic lymphangioma and a mesenteric chylous cyst was made not before surgery. The postoperative course was uneventful. Problems of diagnostic, differential diagnosis and therapy are presented and differences in etiology, histology and location are discussed.

[Sonographic appearances of mesenteric cysts--report of 2 cases].

Mesenteric cyst is defined as a cystic mass located in the mesentery, and has rarely been reported. Before the clinical use of ultrasound (US), the imaging diagnosis of the abdominal mass depended on plain X-ray films and contrast examinations to delineate the space occupying lesion. The later use of US enables us to readily identify mass character. For example, whether it is cystic or solid, with or without septum, or whether there is sediment in the cyst. US examination is the method of choice in evaluating abdominal masses. Two cases of pediatric mesenteric cysts were brought to our hospital on account of complication. US of the first patient revealed a huge cystic mass with sediment and septae in central abdomen. Mild hydronephrotic change of the right kidney was found. The pathology showed nonepithelial lining multiloculated cyst surrounded by a thick, fibrotic granulomatous wall with suppurative cell infiltration and some calcifications. The histopathological diagnosis was an infected pseudocyst. The other patient had a cyst which twisted the jejunum and resulted in intestinal obstruction. US found dilated intestinal loops and a septate cystic mass in epigastrium. The pathology showed a multiloculated cyst with mesothelial lining, representing a mesothelial cyst. Both patients were treated surgically and had an uneventful recovery. In this article we described and explained the findings on US, discussed the differential diagnoses and compared different imaging modalities.

Mesenteric cyst neoformation. A case report.

Mesenteric cysts are rare lesions, with 1 case per 100,000 hospital admission reported. They have to be differentiated from ovarian cysts, gastrointestinal duplications and desmoid cysts. The symptoms are variable, ranging from asymptomatic cases with incidental discovery to chronic abdominal discomfort and acute abdomen. They are usually correlated to the location and the size of the lesion. Abdominal ultrasonography and computed tomography may lead to a correct diagnosis, which is regularly made at the time of abdominal exploration. Surgery is the treatment of choice, consisting with the removal of the cyst, eventually associated with bowel resection. It has to be radical in order to prevent the recurrence of the disease. A case of mesenteric cyst in a sixty-nine-years-old woman hospitalized for chronic abdominal pain is reported. In this case the cyst has been enucleated from the mesentery with open surgery without the need for bowel resection.

Large gastric mesenteric cyst: case report and literature review.

The case is a 33-year-old white female presenting with a 3-day history of abdominal pain. On initial examination, she was found to have significant right lower quadrant tenderness. Workup included computed tomography, which demonstrated a large cystic mass appearing to be of ovarian origin. The patient required an exploratory laparotomy, at which time she was found to have a large cyst involving the lesser curvature of her stomach. The cyst was successfully resected, and the patient had a rapid postoperative recovery with complete resolution of symptoms. Histopathologic evaluation of the specimen identified a mesenteric cyst. Mesenteric cysts are uncommon; gastric involvement is exceedingly rare. A review of the literature is presented.

Peritonitis caused by a ruptured infected mesenteric cyst.

Perforation of a mesenteric cyst is a very rare complication of a very unusual lesion. Acute presentation is the rule in half of all affected children. Ultrasonography and computed tomography are the best preoperative diagnostic tools. The treatment of choice is an urgent laparotomy and complete cyst removal. Results are good in cases that are operated on in a timely manner.

Laparoscopic excision of a mesenteric cyst during pregnancy.

BACKGROUND: Laparoscopic management of mesenteric cysts during pregnancy has not been reported before. CASE REPORT: A young woman with a mesenteric cyst associated with a crossed ectopic kidney, underwent laparoscopic excision of the cyst in the second trimester of pregnancy. The procedure was completed without complications, and the patient was discharged on the third postoperative day. Thereafter, the pregnancy progressed uneventfully, and she delivered a healthy baby at term. CONCLUSION: Laparoscopic management of mesenteric cysts during pregnancy is feasible, safe, and less invasive than laparotomy when performed in select patients by experienced surgeons.

[Mesenteric cyst. A review].

The mesenteric cyst is a tumor of multiple origins, that undoubtedly presents with greater frequency than that referred in published series. Nevertheless, it continues to be a rare entity. Due to absence of characteristic signs and symptoms, diagnosis is only made once these lesions have reached a size, sufficiently large to be palpable or when they cause compression on organs or neighboring structures. The cyst can present with chronic manifestations such as diffuse abdominal pain imprecisely located but associated with palpable mass, or due to complications of the cyst or due to compression of adjacent structures. Diagnosis is confirmed by imaging studies, such as the different ultrasound modalities, computed tomography (CT) scan, and magnetic resonance imaging (MRI). A differential diagnosis must be made to exclude other intra-abdominal or retro-peritoneal tumors. Optimum treatment is extirpation of the cyst. On occasion it is also necessary to remove the adjacent organ due to the impossibility of enucleating cyst. marsupialization of the cyst or drainage into peritoneal cavity, have high incidence of recurrence. Surgical treatment can be carried out by minimal invasion techniques.

Mesenteric cysts and intra-abdominal cystic lymphangiomas.

Although mesenteric cysts and intra-abdominal cystic lymphangiomas are uncommon and clinically confusing lesions, histologic and ultrastructural evidence suggests that they are pathologically distinct. Differentiation of these lesions is important since lymphangiomas may follow a proliferative and invasive course. Of 28 cases documented at laparotomy, histologically eight patients (29%) had cystic lymphangiomas and 20 patients (71%) had mesenteric cysts. Lymphangioma was found to be exclusively a disease of childhood and young adulthood (mean age, 10 years); mesenteric cyst was found in all age groups (mean age, 44 years), and two thirds of these patients were over 40 years old. Patients with lymphangiomas more frequently were male (75% vs 30%), symptomatic (88% vs 35%), and had ascites (50% vs 0%) and larger lesions (mean, 8.8 vs 4.7 cm) when compared with patients with mesenteric cysts. Complete excision was possible in all but four patients, with no operative deaths and a postoperative complication rate of 7%. After a mean follow-up period of four years, there were no recurrences among 16 patients who had undergone complete excision.

[Mesenteric cysts (author's transl)].

Mesenteric cysts belong to the rare abdominal diseases. Histomorphologically, they are classified as cystic lymphangiomas. Even though most frequently localized in the mesentery of the small intestine, they can originate from any part of the abdominal cavity with two peritoneal linings. The content of the cysts is either serous or chylous possessing immunologic active proteins. This is demonstrated by its highly antibacterial activity. Whereas in children the onset of symptoms is acute due to intestinal obstruction, in adults it is mainly chronic abdominal pains without exact localisation and often in combination with a longstanding palpable tumour. In addition to routine procedure the diagnostics includes sonography, cavography and barium meal radiography of the stomach and intestines. In some cases, especially those with solid parts angiography and computer-tomography are of additional value. Surgery is the therapeutic method of choice. Preference is given to enucleation and resection with or without removal of part of the intestine corresponding to the mesentery baring the cyst. Drainage methods are of historical interest only. In our 9 cases (3 children and 6 adults) resection was performed in 7 and enucleation in 2 cases. The postoperative courses were uneventful.

[Ultrasonic diagnosis in children with mesenteric cysts].

Two cases of Mesenteric Cysts in infancy are described. Since there is no continuity with the lumen of the bowel radiological evaluation may be very difficult. In contrast abdominal sonography can give information about size, contents and position in relation to other abdominal organs. The use of ultrasound shortens the preoperative workup and certainly reduces the number of X-ray examinations.

Mesenteric cysts are lesions of rare chech, they can manifest or their painful abdominal pathology or comprehensive by effect mass. Today with imaging methods, especially the U.S., diffuse with capillarity in the hospitals, it possible to point at them also by chance for others types of problems. When possible, the FNAB, is diriment by diagnostic point of view. New imaging methods give an aimed operative planning, that spares to the patient a blindly operation on an unprepared intestine.

Mesenteric cyst: sonographic findings.

BACKGROUND: Mesenteric cyst (MC) is a relatively rare disease, and its sonographic characteristics have not been sufficiently analyzed. METHODS: We studied the sonographic findings of eight patients with MC, with attention paid to its size, shape, internal echoes, and especially the presence or absence of lateral shadowing and the mode of back echoes. In four cases, the sound velocity and acoustic impedance of cystic fluid were also measured. The mode of blood flow was evaluated by color Doppler sonography. RESULTS: Six cases showed an oval or comma-shaped mass. Internal echoes were present in six cases, and two of them showed a pseudosolid pattern. In these cases, M-mode sonography confirmed the movement of these internal echoes. Only one case showed a posterior echo enhancement, and no case showed lateral shadowing. Sound velocity measured in four cases was 1,515-1,537 m/s, with an acoustic impedance of 1.550-1.576 kg/m2/s. No blood flow signals were obtained from the lesion. CONCLUSION: MC exhibits so many patterns on ultrasound that we should consider the possibility of MC when encountering an avascular oval mesenteric mass.
