| pubmed-article:6389011 | pubmed:abstractText | Adrenal carcinomas are rare. We present four surgically and pathologically proved large right adrenal carcinomas studied by computed tomography, angiography, and other imaging modalities. Computed tomography demonstrated large nonhomogeneous right upper quadrant masses in all four cases, but the adrenal origin of the mass could not be ascertained by computed tomography in three patients due to the transverse display of the anatomy. Ultrasonography provided important additional information in these cases. Arteriography was diagnostic in each case by demonstrating minimal to marked tumor vascularity supplied by adrenal arteries. We also present, for differential diagnostic purposes, a proved benign adrenal hemorrhagic cyst with computed tomography and angiography findings indistinguishable from those of adrenal carcinomas. Computed tomography does not eliminate the need for angiography in patients with large right upper quadrant masses suspected of being an adrenal carcinoma. | lld:pubmed |
