Bilateral adrenal abnormalities are not infrequently encountered during routine daily radiology practice. The differential diagnoses of bilateral adrenal abnormalities include neoplastic and non-neoplastic entities. The bilateral adrenal tumors include metastasis, lymphoma, neuroblastoma, pheochromocytoma, adenoma, and myelolipoma. Non-neoplastic bilateral adrenal masses include infectious processes and haematomas. There are different diffuse bilateral adrenal changes such as adrenal atrophy, adrenal enlargement, adrenal calcifications, and altered adrenal enhancement. In this pictorial review article, we will discuss the imaging features of these entities with emphasis on their clinical implications.
在日常放射学实践中，经常会发现双侧肾上腺异常。双侧肾上腺异常的鉴别诊断包括肿瘤性和非肿瘤性病变。双侧肾上腺肿瘤包括转移瘤、淋巴瘤、神经母细胞瘤、嗜铬细胞瘤、腺瘤和骨髓脂肪瘤。非肿瘤性双侧肾上腺肿块包括感染性病变和血肿。还有不同的弥漫性双侧肾上腺改变，如肾上腺萎缩、肾上腺增大、肾上腺钙化和肾上腺强化改变。在这篇影像学综述文章中，我们将讨论这些病变的影像学特征，并重点讨论其临床意义。
