Contribution of CT to characterization of focal nodular hyperplasia of the liver.

Our personal series of 20 cases of focal nodular hyperplasia (FNH) of the liver is presented. All lesions were studied with computed tomography (CT), 16 of which with surgical control. Retrospective evaluation of the CT features of the identified FNH, along with those of five hepatocellular adenomas (HCA) and 30 hepatocellular carcinomas (HCC), allowed the definition of specific patterns leading to a correct characterization of FNH in 78% of cases. This greatly reduced the diagnostic errors, with the sole exception of patients with fatty liver in whom nuclear medicine may eventually provide a correct characterization. Fine-needle biopsy is thus only necessary in the dubious cases. A precise diagnostic workup of FNH is necessary, since it may avoid the surgical intervention.

Cystic islet cell tumors of the pancreas. A clinico-pathological report of two nonfunctioning cases and review of the literature.

Cystic islet cell tumors of the pancreas are extremely rare. The authors report their personal experience with two cases of nonfunctioning cystic endocrine neoplasms. The tumor was diagnosed preoperatively in one case by ultrasonography (US)-guided fine-needle aspiration cytology, while in the other it was identified only in the surgical specimen after a clinical-radiologic diagnosis of pancreatic mucinous cystic tumor. Immunohistochemical assay showed positivity for the generic neuroendocrine markers (neuron specific enolase, or NSE, synaptophysin, and chromogranin A) in both cases and also for glucagon in one case. The neoplasms were resected by distal pancreatectomy with splenectomy and intermediate pancreatectomy respectively. Both patients are alive and recurrence-free 6 mo and 2.5 yr, respectively, after surgery. The authors also review the existing literature, discussing the pathogenesis of such tumors and the imaging techniques and surgical strategies adopted in their management.

Intraoperative ultrasonography in pancreatic cancer.

Intraoperative ultrasonography (I.US) has been introduced in order to overcome the limits of the preoperative imaging modalities (notably, ultrasonography and computed tomography), both in pancreatic cancer diagnosis and staging. The authors' experience encompasses 32 cases, selected according to the following criteria: lesions that could not be detected both preoperatively and at surgical exploration; lesions detected but not properly characterized, requiring differential diagnosis between cancer and pancreatitis; tumoral lesions with a perspective of radical surgery, in which the preoperative judgment of resectability had to be verified. In the only case of the first group, I.US allowed the identification of a small cancer in a jaundiced patient. In the 11 cases of the second group, I.US-guided fine-needle aspiration biopsy showed three cancers; however, among the other 8 lesions classified as pancreatitis there was one false negative diagnosis (a tumoral mass with liver metastases was demonstrated by computed tomography 6 mo later). Regarding the intraoperative staging of the proven cancers (20 cases of the third group; 4 cases of the first and second groups), I.US changed the planned surgical approach in 9 cases (showing vascular involvement or detecting liver metastases and enlarged lymph nodes not seen preoperatively); in 12 cases it confirmed the possibility of radical surgery. Finally, in the remaining 3 cases, I.US provided dubious information: only vascular dissection during surgery could achieve a correct evaluation, ruling out vascular involvement and thus allowing tumor resection.

[The treatment of acute cholecystitis by percutaneous cholecystostomy].

The authors report on their personal experience with percutaneous cholecystostomy (PC) in 36 cases of acute cholecystitis (AC). PC was successful in 34 cases, improving the clinical condition of the patients within the first hour following treatment and normalizing the laboratory data within 24-48 hours. Twenty-seven patients with calculous AC underwent cholecystectomy within 4-15 days. In 6 cases (3 calculous and 3 acalculous ACs) PC was the only treatment performed; in one case (calculous AC) PC was combined with lithotomy, the stone fragments being extracted via the cholecystostomy. According to literature reports, to date PC has been performed mainly--as an alternative to surgical cholecystostomy--on the patients unsuitable for cholecystectomy due to their age or to severe impairment of their conditions. In our experience, the procedure can be performed on a wider range of patients as a final (notably in acalculous AC) or temporary step (notably in calculous AC where it may allow cholecystectomy to be delayed and thus performed under better clinical conditions, with decreased morbidity and mortality risks).

Cystic tumors of the pancreas: evaluation by ultrasonography and computed tomography.

The personal series of 30 cystic tumors of the pancreas [12 serous cystic tumors (SCT) and 18 mucinous cystic tumors (MCT)] is presented. All neoplasms were evaluated with ultrasonography (US) 28 of 30 with computed tomography (CT); the tumoral histotype could be correctly defined in 73% of cases (seven of 12 SCT and 15 of 18 MCT). Percutaneous fine-needle aspiration (FNA) with diagnostic aims (preparation of cytological smears and/or biochemical assays) was performed in only 10 of 30 cases, yielding a 100% sensitivity; on the whole, the combined use of imaging modalities and FNA allowed correct characterization of the cystic tumors in 27 of 30 cases (90%). The usefulness of a precise diagnostic workup of these neoplasms is emphasized, due to their prognostic and therapeutic outcome.

[Magnetic resonance in the study of the temporo-mandibular joint. I. Anatomo-functional findings].

Thirty-four temporomandibular joints (TMJ) were examined in 17 normal subjects with two superconductive MR units at 1T and 1.5T. TMJ evaluation was performed with both SE sequences in occlusal position and with "fast" sequences (flash) during the gradual opening of the mouth. Therefore, both the anatomic features of the TMJs and their dynamic behavior during mouth opening were analyzed. The information acquired allowed the complete and non-invasive evaluation of TMJ function. The knowledge of the normal anatomic and functional patterns is of paramount importance for the diagnostic approach to TMJ pathologic conditions.

[Magnetic resonance imaging in study of the temporo-mandibular joint. II. Pathologic findings].

A total of 107 temporomandibular joints (TMJ) were examined with two superconductive MR units at 1T and 1.5T. In 73 TMJs, MR revealed 55 disk displacements, 7 disk perforations, 10 joint space adhesions, 33 osteoarthrities, 3 avascular necroses of the mandibular condyle, and 25 joint effusions. These abnormalities are described and discussed. In spite of some limitations--e.g., motion artifacts and patients' claustrophobia--MR imaging is the procedure of choice in abnormal TMJs, because it yields useful information as to therapeutic choice (conservative versus surgical). Arthrography can be used as a complementary study technique in the patients with marked disagreement between clinical and MR findings. Arthroscopy should be used as a surgical procedure in abnormal TMJs selected by previous MR studies.

The contribution of ultrasonography and computed tomography in the diagnosis of nonfunctioning islet cell tumors of the pancreas.

The personal series of 12 nonfunctioning islet cell tumors (NFIT) of the pancreas is reported. The ultrasound and computed tomography features of NFIT are analyzed, and a few signs are identified that may be useful in the differential diagnosis vs ductal carcinoma. The necessity to complete the diagnostic work up by means of fine needle aspiration biopsy and cytologic smears is also emphasized.

[The distal spleno-renal anastomosis of Warren (author's transl)].

This is a report on 28 Warren-Shunts, 17 of these patients had undergone clinical, hematological and angiographic controls 2--46 (mean 10) months after the operation. The critical evaluation of the results shows that the Warren derivation, which is selective at the moment of operation, develops in the following time some hepatofugal circulation. This is a more radical effect than the intended drainage of the gastro-esophageal venous bed alone.

Accuracy of computed tomography in the screening of obstructive jaundice.

Percutaneous transhepatic cholangiography (PTC) has come back into greater use thanks to Chiba's needle. PTC, however, is useful only in obstructive jaundice (OJ). Since in OJ the dilatation of the intrahepatic biliary tract (IHBTD) is constant, the authors discussed CTs reliability in evaluating IHBTD in a series of 33 patients with OJ studied with PTC. The threshold of CT diagnosis of IHBTD was found to be equal to a doubled caliber of the normal biliary tract. This value is reached by 85% of the patients 2 weeks after the onset of OJ and in 98% between 2 and 3 weeks. CT is therefore usable as a screening method of PTC, as long as it is not performed before 2 weeks after the onset of OJ. After 2 weeks, if CT does not reveal IHBTD, it is possible to exclude OJ.

[The role of computed axial tomography in pancreatic emergencies (author's transl)].

The role of CT in acute diseases of the pancreas is discussed, in the light of personal experience (25 cases). In acute pancreatitis (22 cases), CT was useful in particular for: differential diagnosis between the necrotic-hemorrhagic type and the edematous type; detection of extra-pancreatic collections and evaluation of their extent; post-operative follow-up of necrotic-hemorrhagic pancreatitis. In the other more rare empergencies (3 cases), CT could recognize respectively the rupture of an infected pseudo-cyst, and intra-cystic hemorrhage, a mediastinitis due to the spread of ascitic fluid containing pancreatic enzymes into the mediastinum. CT always provided diagnostic information which the other radiological techniques did not provide; therefore in acute diseases of the pancreas CT is the method of choice.

[Distal termino-lateral spleno-renal anastomosis, using the Warren technic].

The authors describe 23 cases of distal splenorenal derivation after Warren. Of these patients, 17 received a complete followup clinical hematological and angiographic examination at an average remove of 10 months after surgery. The authors discuss their results and submit that the Warren operation, while really selcetive in most cases when performed, in the long run tends to shung rather too much blood away from the liver; in other words, the effectiveness of the shunt tends to exceed the intended drainage,which should be restricted to the gastro-esophageal vascular bed.

Selective arterial embolization in renal tumors.

Selective arterial embolization with Gelfoam was performed in 45 cases of hypernephroma. In 33 cases this technique has been utilized as preoperative procedure and almost always (97%) nephrectomy was facilitated: 97% of the cases had slight or moderate operative bleeding; in 82% of the cases separation of the tumor-containing kidney from adjacent tissues was easy. Embolization has been employed in 12 inoperable patients and was effective mainly in management of bleeding. Angiographic controls after embolization (from 13 to 162 days) were performed 8 times and it was assessed that the efficacy of the procedure on primary tumor growth is limited in time by renal artery revascularization. The embolized patients never presented severe complications, except several episodes of transitory renal failure.

Angiographic diagnosis of endocrine tumors of the pancreas.

The angiographic findings in 18 patients with endocrine tumors of the pancreas are analyzed. A literature review (262 cases) is performed in order to assess the accuracy of angiography in diagnosing islet cell tumors, in particular multiple and small (less than 1 cm) lesions. Problems of differential diagnosis of pancreatic and extrapancreatic structures and lesions are discussed.

Critical evaluation of renal masses' angiography.

152 consecutive space occupying renal lesions (54 cancers, 66 single or multiple cysts, 18 pseudotumors, 8 inflammatory lesions, 3 hydronephroses, 3 hehatomas) were studied by selective angiography, considering the signs noted in the three phases: arterial, nephrographic, and venous. The frequency of each of these angiographic signs in the different forms of renal pathology was evaluated. Based on this study, pathognomonic angiographic signs were identified for the various types of pathology. For each angiographic sign the 'diagnostic value' was calculated in order to differentiate malignant from benign space-occupying lesions. Dependent on the angiographic phase they are in, these signs constitute the arterial, nephrographic, and venous 'symptom constellation' characteristic of each lesion. The relationship between angiographic signs and either histologic type or size of tumor were analyzed. The causes of false positives and false negatives were investigated. The value of certain angiographic signs for a correct diagnosis of the cases judged as suspect or misinterpreted was discussed.
