Use of magnetic resonance imaging scanning in adrenocortical carcinoma with vena caval involvement.

We report on 2 cases of an adrenocortical carcinoma with vena caval involvement. Preoperative evaluation included a magnetic resonance imaging (MRI) scan confirming the presence of vena caval involvement. Extremely precise detail of the vena caval tumor thrombus was very helpful in preparing for the surgical extirpation.

Case report. Unilateral renal vein thrombosis without proteinuria.

Unilateral renal vein thrombosis occurred in a patient who was found to have an adenocarcinoma and who had previously been subjected to trauma. Proteinuria was absent throughout the patient's entire clinical course, despite its well known association with renal vein thrombosis. However, other findings suggestive of renal vein thrombosis, including back pain and tenderness, hematuria and an enlarged kidney were present.

Partial duplication of the male urethra.

A case of partial duplication of the male urethra (bifid urethra) is presented. This case is unusual because of the late presentation with incontinence, the normality of the primary urethra and the markedly lateral course of the accessory urethra. An anatomic and embryological classification is presented.
