[Increased fasting gallbladder volume: a new ultrasonic sign of cirrhosis?].

Ultrasound was used to calculate fasting gallbladder volume in three groups of patients: 90 with cirrhosis (alcoholic in 75 cases), 41 with non cirrhotic liver disease (alcoholic in 14 cases), and 38 controls. Gallbladder volume was evaluated according to sex, age, alcoholism, presence of gallstones, time of diagnosis, and biological tests of hepatocellular function. Mean fasting gallbladder volume was significantly higher in cirrhotic patients (45.89 +/- 32.65 ml, m +/- 1 SD) than in patients with non cirrhotic liver disease (25.31 +/- 14.08 ml) and in control subjects (21.28 +/- 10.30 ml) (P less than 0.001), but there was a great overlap between individual results in each group. No relationship was found between gallbladder volume and all clinical and biological tested parameters, except for decreased prothrombin time (P less than 0.02). Further studies are necessary to consider this ultrasound sign as an useful diagnostic tool in cirrhosis.

[Portal venous system calcifications. Study of 3 cases and review of the literature].

Three cases of calcifications of the portal system are reported in men aged 42, 53 and 40 years old. Two patients had alcoholic cirrhosis, and one had familial congenital hepatic fibrosis, respectively. Calcifications were discovered fortuitously on plain abdominal films. Ultrasound and computed tomography studies, and in two cases, angiography, confirmed that calcifications were located within the vein walls. The veins involved were the portal vein in 3 cases, the splenic vein in 2 cases, and the superior mesenteric and left gastric veins in one case each. Investigations demonstrated splenoportal and splenic thrombosis in 2 cases, whereas the portal vein system was patent in the other. In two cases, the splenic artery was aneurysmal, associated with several intrasplenic arterial aneurysms in one. Based on these three cases, combined with a review of the literature of 123 previous reports, the features of this rare entity are described with emphasis placed on the value of computed tomography studies.

[Carney's syndrome disclosed by hemoperitoneum].

The authors report a case of Carney's triad in a blood-group O woman who successively sustained a) at age 13, a multicentric gastric leiomyoblastoma revealed by an hemoperitoneum; b) 6 years later, a pulmonary chondroma diagnosed by chest standard roentgenogram and CT scan, associated with leiomyoblastoma recurrence and hepatic metastases; c) 10 years later, a juxta-carotid tumor of unknown (paraganglion?) origin. This patient is presently in good clinical condition, in spite of hepatic metastases known for 5 years. Based on this case and the 33 previously reported cases, the main features of this very unusual entity are analyzed.

Gastric leiomyoblastoma: diagnosis by CT and ultrasonography.

A case of gastric leiomyoblastoma is reported in a 57-year-old woman complaining of upper abdominal discomfort. Ultrasound and CT examinations discovered an epigastric mass, and ultrasound manoeuvers by multiple positioning allowed to refer it to a gastric origin. Definitive diagnosis was established by histological examination of the surgically removed tumor. The authors emphasize the interest of the radiological examinations, particularly ultrasound and CT, in this rare condition.
