[Intralingual dermoid cyst: imaging features of a giant cyst].

Dermoid cysts of the oral cavity are rare and most commonly involve the floor of mouth. Intralingual dermoid cysts are extremely rare and usually large at the time of diagnosis in adult patients. We report the case of 6 year old girl with macroglossia and swallowing and respiratory difficulties due to a giant intralingual dermoid cyst. Ultrasonography showed a large cystic intralingual lesion. MRI allowed accurate evaluation of the size, the extension and the relationship of the cystic mass with adjacent structures, the fat component of the cystic mass confirmed the dermoid origin. This case illustrates the diagnostic contribution of US and MRI in this disease.

Obstructive jaundice caused by primary choledochal hydatid cyst mimicking radiologically choledochal cyst.

A 12-year-old girl with obstructive jaundice that was initially misinterpreted radiologically as having choledochal cyst is presented. A primary hydatid cyst in the wall of the common bile duct causing obstruction was found at operation. The authors emphasize that hydatid cyst should be included in the list of differential diagnoses of obstructive jaundice and cystic lesions located around the biliopancreatic junction in children.

[Calcifying solitary bone cyst of the sacrum--A rare type of bone cyst and its unknown localisation, differential diagnosis and management].

AIM: The diagnostic procedures and management of calcifying bone lesions occurring in the sacrum. METHOD: A case report of a rare type of bone cyst at an unknown localisation including the differential diagnosis and management. RESULTS: Low back pain of a 41-year-old women was correlated with a calcifying bone formation of the sacrum on X-ray, demonstrating cystic, solid and exophytic components. On radionuclide bone scan, additional skeletal lesions were ruled out, the focus showed an increased uptake. An inflammatory process was excluded by lab studies. On computed tomography and magnetic resonance imaging, the calcifying bone formation was identified as surrounding the sacral canal, respecting the anatomical borders. Considering this anatomic region, a neurogenic tumor could be eliminated by the absence of neurological disorders, but the radiologic feature of this osseogenic process was not clear enough for classification. Hence, an incisional biopsy was essentially required. Describing the lesion as a bony cavity, the operating surgeon could macroscopically exclude an chordom a (known to be soft consistency). The histological work-up classified this tumor-like lesion as a calcifying solitary bone cyst (CSBC). A dorsal exostosis causing the complaint of the patient was resected. The patient became asymptomatic. CONCLUSION: For the first time, a calcifying solitary bone cyst located in the sacrum is described, By sole resection of a dorsal exostosis causing the complaint, an overtreatment of grave consequences was avoided.

Intramedullary epidermoid cyst of the cervical spinal cord associated with an extraspinal neuroenteric cyst: case report.

A 4-year-old girl presented with an intramedullary epidermoid cyst of the cervical spinal cord. The clinical, radiological, and surgical features and a brief critical review of the literature are included in this report. The cyst contents were removed totally in two operations. The child had a coexisting neuroenteric cyst in the posterior mediastinum. To our knowledge, this coexistence has not been previously reported. Contemporary imaging modes and prospects of the surgical treatment are discussed.

Solitary non-parasitic liver cyst treated by cyst-gastrostomy.

A 66 year old female presented with a symptomatic solitary non-parasitic liver cyst. This was treated by a cyst-gastrostomy following which the patient has remained well without complications for 12 years. Given an appropriate anatomical relationship of cyst and stomach, this would appear to be a safe and effective operation.

Eruptive vellus hair cyst and steatocystoma multiplex: hybrid cysts.

Steatocystoma multiplex (SM) and eruptive vellus hair cyst (EVHC) are known as clinically similar but histologically distinct entities, first described by Jamieson in 1873 and Esterly et al. in 1977, respectively. Herein we describe a 24-year-old female patient with both lesions on the anterior chest wall. The biopsy showed portions of two cysts close together with features of SM in one part and features of EVHC in the other part. Our case gives further evidence that these two conditions are closely related. To the best of our knowledge this is the first case where such an anatomically close relationship between these two types of cysts has been described.

Development of a malignant proliferating trichilemmal cyst in a patient with multiple trichilemmal cysts.

A case of multiple trichilemmal cysts is presented. After trauma, a large tumor developed on one of the cysts. The histologic features of this tumor were similar to those of proliferating trichilemmal cyst, but some of the tumor cells showed definite nuclear atypicality. The malignant potential of this tumor was confirmed by later development of metastases to the regional lymph nodes.

Isolated adrenocorticotrophin deficiency associated with anti-pituitary antibodies, pituitary cyst, sphenoidal cyst and pineal tumor.

This paper reports a rare case of isolated ACTH deficiency associated with anti-pituitary antibodies, pituitary cyst, sphenoidal cyst and pineal tumor. A 68-year-old man consulted our clinic for general fatigue. Laboratory data showed low plasma adrenocorticotrophin (ACTH) and cortisol levels with blunted responses to insulin-induced hypoglycemia and corticotrophin releasing factor (CRF). Urinary 17-OHCS was low but responded to ACTH-Z administration. No other pituitary functions were impaired. Antibodies to the cytoplasm of rat pituitary and the surface of GH3 cells were detected in the serum. The magnetic resonance imaging (MRI) showed a high signal intensity mass in the anterior pituitary and in the sphenoidal sinus in both T1 and T2 weighted images as well as a low signal intensity mass in a T1 weighted image of the pineal region. Transsphenoidal surgery was performed to resect the mass in the sphenoid sinus and in the pituitary. Pathological studies showed a benign cyst in the sphenoid sinus, and fibrous degeneration and decreased basophils in the pituitary. No infiltrative mononuclear cells were detected in the pituitary. Immunohistochemical studies revealed a decrease in the number of ACTH-producing cells in the pituitary. The patient was well maintained by glucocorticoid replacement without any growth of a possibly benign pineal tumor.

[Treatment of liver or renal cyst by percutaneous injection of TH glue into the cyst cavities].

From April 1995 to May 1996, 32 cases of liver or renal cyts were detected by B ultra sound. Among them, TH glue was injected into the cyst to make it coagulated and occluded in 4 cases of liver cyst and 8 cases of renal cyst after intracapsular fluid was abstracted. The curative effect was good. The curative rate of single injection was 83.3%. The period of treatment and the curative rate were obviously different from the past methods. The present method is easy, quick, small wounded, few complicated and no toxic and side effects.

[Bronchogenic cyst of the right hemidiaphragm mimicking a hydatic cyst of the liver].

Ectopic subdiaphragmatic development of a bronchogenic cyst is rare. We report the case of a 28-year-old woman with a symptomatic bronchogenic cyst of the right hemidiaphragm simulating a hydatic cyst of the liver on ultrasonography and CT scan. Diagnosis of a diaphragmatic lesion was made during laparotomy, and complete resection was successful. Final diagnosis was done on pathology.

[Dentigerous cysts of children treated by cyst wall enucleation. Report of eleven cases].

The present paper describes ten children with eleven cases of dentigerous cysts which were treated by extraction of the primary teeth, cyst wall enucleation and lingual-arch spacemaintainer. The patients were seven boys and three girls, with a mean age of nine years two months, in Hellman's Dental Age IIIA and IIIB. In eight of the cases, the mandibular second premolar was involved, and of the remainder, two cases involved the first premolar, and one case, a maxillary lateral incisor. In eight out of the eleven cases, the pulp of the primary tooth had been treated. Radiographically, nine cases exhibited a pericoronal space of 15 mm-35 mm and two cases 50 mm-55 mm. The material for histological examination, typically, gave the appearance of a stratified squamous epithelium showing chronic inflammation. Healing took place more rapidly than routine marsupialization. In eight cases the successor erupted in the normal position without orthodontic treatment, in two cases with light orthodontic power. In one case the behavior of the permanent tooth was kept under observation. From the above, this approach to treatment by cyst wall enucleation and lingual-arch spacemaintainer would appear to be very useful for the young child.

[Congenital cyst of the common bile duct. Surgical treatment with total excision of the cyst].

Congenital choledochal cyst (CChC) has a very low frequency in our population; it is more frequent among females and its pattern of inheritance is multifactorial. The frequency of CChC in our population was 1 per 20,000 to 1 per 30,000 hospitalized patients in the pediatrics department of the Hospital Juarez and Hospital Infantil de Tacubaya, respectively. Four new cases of CChC are reported, two school children and two teenagers. Pre-operative diagnosis was accomplished clinically, which is the most precise non-invasive method. The most effective actual diagnostic methods include ultrasonography, CAT scan, and basic laboratory data, which can corroborate the clinical diagnosis of CChC with 100% certainty. The surgical treatment of CChC is controversial, but the surgical procedures of choice are choledochocystojejunostomy with total cyst removal, Roux's Y, and cholecystectomy. One case was treated with latero-terminal choledochocystojejunostomy and 3 cases with total removal of the cyst. The results were excellent.

Neonatal ovarian cyst: prenatal diagnosis and analysis of the cyst fluid.

Ovarian cysts of clinical significance are uncommon in the fetus and neonate. The authors diagnosed a large fetal cyst prenatally by ultrasound scan and removed it in the neonatal period. Analysis of the fluid obtained from the cyst demonstrated a capacity of the fetal ovary to synthesize estrogen and progesterone.

Cementum-like bone production in solitary bone cysts. (so-called "cementoma" of long bones). Report of three cases. Electron microscopic observations supporting a synovial origin to the simple bone cyst.

Three cases of simple bone cysts (S.B.C) in association with cementum-like bone production are reported. Analysis of our cases and the 2 previously reported in the literature as so-called cementomas has led us to conclude that the "cementoma" of long bone is not a distinct entity, but merely, a form of S.B.C. associated with a peculiar, poorly cellular form of bone which mimics tooth cementum by light microscopy only. Electron microscopic studies of this substance demonstrate collagen fibers and numerous matrix vesicles which form the initial sites of calcification. Matrix vesicles are a product of osteoblastic activity and are never found in the cementum of the tooth or oral cementum producing tumors. We also report the first ultramiscroscopic observations on the wall of the simple bone cyst and its lining. Two cell types constitute the lining, having features identical to those described for type A and type B synovial cells. Because of this new observation, we believe, the most reasonable explanation for the simple bone cyst is that it represents a congenital "rest" of synovial tissue displaced into the thin, cortical metaphyseal region of bones at the synovial-capsularbone reflection. Its benign nature and slow growth would explain its discovery in early childhood and the marked preponderance of its proximal humerofemoral location dependent upon the fact that these 2 bones have the largest area of capsular to metaphyseal bone reflection.

A lymphoepithelial cyst (branchial cyst) in the floor of the mouth.

Lymphoepithelial cysts are developmental, but their pathogenesis is unknown. The classical explanation is that they are derived from remnants of the branchial arches or clefts. This has been disputed, and it is likely that most arise from epithelium, possibly of tonsillar or salivary origin, that becomes entrapped by lymphoid tissue. This report describes a lymphoepithelial cyst in a 29-year-old man. The cyst was situated on the right side of the floor of the mouth adjacent to the lingual frenum. Its appearance supports both branchiogenic and the entrapment theories.

A special cyst puncture catheter for use in thick-walled or mobile intracranial cysts.

Having encountered a number of thick-walled or mobile symptomatic intracranial cysts that have resisted stereotactic puncture with standard blunt-ended ventricular catheters, the authors have designed a cyst puncture catheter that has a number of features helpful in overcoming this problem. The catheter and its use are described, and examples of difficult-to-puncture cysts are given.
