title: Ultrasonography of adrenal masses: unusual manifestations.
abstract: Forty patients with pathologically-proved adrenal masses, and two patients with extra-adrenal pheochromocytomas, were examined with gray scale B-scan. The authors describe unusual echo patterns of adrenal masses due to necrosis or hemorrhage, variations in the effects of large adrenal masses on surrounding organs and vessels, and the differential diagnosis. The complementary role of computed tomography is also discussed.
