The findings at computed tomography (CT) of the adrenal glands in 58 patients are presented. Most patients (50) were referred for suspected adrenal dysfunction. In three, adrenal masses were suspected from other radiological studies. Three patients had palpable abdominal masses, and incidental adrenal metastases were found in two. Pathological findings included pheochromocytomas (nine patients), adrenocortical adenomas (six), adrenocortical carcinomas (three), metastases (two), and one example each of myelolipoma, hemorrhagic renal cyst, and probable granuloma. Of 24 adrenal masses, 23 were clearly apparent in the scans and one was suspected. The smallest tumor diagnosed was 0.5 cm in diameter. There was on false positive diagnosis of a small tumor and no known false negatives. Because of their consistent location and unusual shape and because they are usually surrounded by retroperitoneal fat, the adrenal glands are ideal organs for study by CT, a highly accurate method for detecting and excluding mass lesions that may render arteriography and venography unnecessary. Surgery was performed in five patients with tumors following localization by CT only. Limitations and potential diagnostic pitfalls in interpretation are discussed.
