Bilateral primary synchronous renal cell carcinoma.
We report a case of bilateral primary "synchronous" renal cell carcinoma (RCC) with different differentiation rates. Computed tomography (CT), ultrasonography (US), angiography, and fine needle aspiration biopsy (FNAB) were performed followed by right radical and left partial nephrectomy. Findings on ultrasonography were non-specific, CT scan showed bilateral solid renal mass. On angiography of the right renal artery no tumoral vessels were seen and FNAB yielded a false negative result on the left side. Histological examination revealed a cystic renal cell carcinoma on the right and a multinodular renal cell carcinoma on the left side. We could not find similar report in the current literature.
Crohn's disease and sclerosing cholangitis: CT and PTC diagnosis, with MR findings.
Computed tomography (CT), percutaneous transhepatic cholangiography (PTC) and magnetic resonance imaging (MRI) findings in a case of sclerosing cholangitis associated with Crohn's disease of the colon and terminal ileum are described. CT gives additional information on dilatation of peripheral bile ducts and confirms findings of PTC, i.e. a decreased arborization of the biliary tree, a nodular appearance of the common bile duct and multifocal bile duct strictures. CT findings could be recognized on MRI which provided no additional information.
