Intracaval extension of pheochromocytoma ultrasonographic demonstration.
Pheochromocytoma is a relatively rare neoplasm, one which may also be found in association with other neoplasms. Preoperative demonstration of malignant pheochromocytoma into the inferior vena cava is uncommon. This is the first confirmed report of the ultrasonographic demonstration of inferior vena cava extension of a malignant pheochromocytoma. The coexistance of a primary bronchio-alveolar adenocarcinoma with this lesion has also not been previously reported.
