Case report. Renal oncocytoma.

In a case of renal oncocytic adenoma, a "spoke-wheel" pattern of pathological vessels was observed at arteriography of the highly vascular tumor. Computed tomograpy revealed a solid mass with attenuation value significantly higher than that of the normal renal tissue.

[Cholangiographic appearance of the intraphepatic bile ducts (author's transl)].

Percutaneous transphepatic cholangiography patterns of intrahepatic bile ducts in 134 patients were analysed. The majority of case material consisted of gallstone disease and complications of its surgery (44 cases) and secondary or primary neoplasms of the liver (40 cases). A satisfactory filling of the peripheral bile ducts was obtained after drainage of bile and with an injection of somewhat increased quantities of contrast medium into the biliary system. PTC was found to be highly effective in detecting space occupying lesions of neoplastic origin i.e. sensitivity-90 percent, specificity-95 percent, predictive value of a positive result-88 percent. PTC patterns of liver cirrhosis with concommitant extraheptic obstruction, chronic cholangitis, congenital ectasia of the bile ducts, liver abscesses are described. Although PTC is aimed primarily at the detection of nature and level of the extraheptic biliary obstruction there is no essential reason for neglecting its possibilities in recognizing intrahepatic disease.

[The vascular supply congenital high renal ectopia (author's transl)].

The angiographic findings in two cases of congenital high renal ectopia are described. Elongation and straightening of the renal arteries, pre-renal branching, transverse or inverted position and typical deformity of the kidneys make up the anatomical components of this anomaly. The previously held view of high origin of the renal vessels has not been confirmed. High origin of the renal arteries from the abdominal aorta does not distinguish congenital from acquired renal ectopia, as may occur after trauma.

A failure to improve radiologists' performances in diagnosing pulmonary lesions by a computer-aided approach.

A traditional radiological evaluation of five lung diseases and their computer-aided diagnosis with Bayes' approach, were based on the plain chest film. Parameters of diagnostic performance for 12 radiologists, who made 1224 diagnoses by each method, were compared. Under the conditions of this study the use of a computer-aided method did not improve radiologists' performances independently of their diagnostic ability and experience.
