Metastatic involvement of the adrenal glands is a frequent complication of bronchogenic carcinoma, occuring in up to 33% of these patients. Examination of ten patients with adrenal metastases revealed large adrenal masses, occuring bilaterally in five. Five of these patients were examined using the standard bistable technique. These patients demonstrated largely echofree masses with only occasional scattered internal echoes. The remaining five patients were examined with the gray scale technique. With the added resolution afforded by the use of gray scale, the masses in these patients showed a more uniform distribution of echoes. Presence of a margin between the kidney and the mass, and displacement of the kidney inferiorly, posteriorly, and laterally is used to differentiated between upper pole renal masses and those of adrenal origin. Autopsy confirmation was obtained in six of the patients.
肾上腺转移是支气管源性癌的常见并发症，在高达33%的此类患者中出现。对10例肾上腺转移患者的检查发现肾上腺有大肿块，其中5例为双侧发病。其中5例患者采用标准双稳态技术进行检查。这些患者的肿块大多为无回声，仅偶尔有散在的内部回声。其余5例患者采用灰阶技术进行检查。由于使用灰阶提供了更高的分辨率，这些患者的肿块回声分布更均匀。肾与肿块之间边缘的存在以及肾向下、向后和向外侧的移位用于区分肾上极肿块和肾上腺来源的肿块。6例患者获得了尸检证实。
