Unusual surgical approach to the treatment of renal cell carcinoma extending into the right atrium through the inferior vena cava.

We report an unusual surgical management of renal cell carcinoma with inferior vena cava and right atrial thrombosis. Successful management is dependent upon preoperative assessment to determine the extent of the disease, tumor thrombi has not infiltrated the walls of the vena cava, and a well planned surgical resection.

Purpose: Recent progress in magnetic resonance imaging (MRI), with contrast-enhanced and steady-state sequences, allows fine depiction of labyrinth abnormalities related to neoplastic, inflammatory, ischemic, degenerative or traumatic disorders. We examined 488 patients with sensorineural hearing loss, vertigo or dizziness, but normal CT findings, to evaluate MR capabilities in showing labyrinth conditions.

Material And Methods: January 1994 to May 1998, four hundred and eighty-eight patients with labyrinthine symptoms were submitted to CT.
