[Renal angiomyolipoma complicated by extension to the renal vein and inferior vena cava]. / Angiomyolipome rénal compliqué d'une extension à la veine rénale et à la veine cave inférieure.

Renal angiomyolipomas are renal hamartomas. They are usually found incidentally, presenting as well-defined echogenic masses on sonography and fat containing tumors on CT and MRI. We report a case of angiomyolipoma with sonographic and CT evidence of extension to the renal vein and inferior vena cava.

[Multidetector CT and MRI in pancreatic diseases]. / Scanner multidétecteur face à l'IRM dans la pathologie du pancréas.

Multidetector CT and MRI are the most efficient non invasive techniques in the assessment of pancreatic diseases. As with MRI, multidetector CT has now become an all in one examination using 2 D and 3 D multiplanar reformations with the ability to perform with high accuracy: a) vascular assessment using MIP reconstruction and b) biliary and pancreatic ducts assessment using minIP reconstruction. This review compares and illustrates the respective advantages of MRI and multidetector CT in the assessment of pancreatic diseases.

[Imaging of the anterior abdominal wall: ultrasonography and CT features]. / Imagerie de la paroi abdominale antérieure: aspects en échographie et en TDM.

US and CT have both become major tools in imaging of the anterior abdominal wall. The goal of this pictorial review is to illustrate the respective roles of US and CT in the evaluation of normal and abnormal anterior abdominal wall.

[Renal varices. X-ray computed tomographic diagnosis and treatment by embolization]. / Varices rénales. Diagnostic tomodensitométrique et traitement par embolisation.

Two cases of recurrent macroscopic hematuria in which the diagnosis of left renal vein varices has suggested on CT are described. Bloody efflux was seen from the left ureteric orifice. On CT scans, tubulated contrast-enhanced densities in left perineal fat were seen. Selective renal angiography was normal. Selective left renal phlebography demonstrated intra and perirenal varices. In the two cases, embolization with metallic coli was successfully performed during left renal phlebography, to stop renal varices flux. Diagnostic and therapeutic modalities of renal varices are discussed with predominant place for CT and phlebography.

Extracorporeal lithotripsy associated with laparoscopic cholecystectomy: results of 60 patients.

Gallbladder extracorporeal lithotripsy was performed on 60 patients before laparoscopic cholecystectomy. Of the 44 cases with solitary stones (range, 17-45 mm; mean +/- SEM, 26.9 +/- 0.1 mm), satisfactory fragmentation was obtained in 77.2%. Of the 16 cases with multiple stones (range, 11-25 mm; mean +/- SEM, 14.9 +/- 0.7 mm), satisfactory fragmentation was obtained in 18.75%. Minimal adverse effects were observed both clinically and macroscopically during surgery. Upon histologic investigation, only two small gallbladder lesions could be attributed to extracorporeal lithotripsy. No changes in blood chemistry tests were recorded. When carried out with high performance equipment, extracorporeal lithotripsy appears to be an interesting procedure that permits an appreciable reduction in the number of parietal wall incisions that need to be widened, therefore simplifying laparoscopic cholecystectomy when dealing with large stones.
