Adrenal cortical carcinoma: preoperative demonstration of right atrial extension by sonography and computerized tomography.

We report a case of adrenal cortical carcinoma with tumor thrombus extending to the right atrium. Tumor extension was demonstrated preoperatively with sonography and computerized tomography. We recommend that both modalities be used when evaluating masses in the suprarenal space. The preoperative diagnosis of tumor extension via the adrenal vein into the inferior vena cava was confirmed at operation.
