Cytologic diagnosis of renal carcinoma in the presence of inferior vena cava obstruction: case report.
Diagnostic work-up and staging of patients with renal tumors usually includes inferior vena cavography. In this case, complete occlusion of the cava was demonstrated by cavography while catheter aspiration yielded tumor fragments diagnostic of renal adenocarcinoma. Transcatheter aspiration in the presence of caval obstruction can provide preoperative tissue diagnosis as well as accurate tumor staging information.
