Adrenal cysts are rare and form a heterogeneous group of lesions that includes (a) parasitic cysts, (b) epithelial cysts, (c) pseudocysts, and (d) endothelial cysts. There is evidence (immunohistochemical and ultrastructural) that both pseudocysts and endothelial cysts are variants of vascular cysts. Adrenal vascular cysts account for 84% of adrenal cysts. They are more common in women and present clinically with abdominal pain or are incidental findings. Their imaging features are not specific. Grossly, both types of adrenal vascular cysts are encapsulated. Pseudocysts are unilocular, thick-walled, and devoid of endothelial lining, whereas endothelial cysts are thin-walled, multilocular, and lined by endothelium. Adrenal vascular cysts probably originate from a preexisting vascular hamartoma. The treatment of choice is surgical excision. The prognosis is excellent.
肾上腺囊肿较为罕见，是一组异质性病变，包括：(a) 寄生虫性囊肿；(b) 上皮性囊肿；(c) 假性囊肿；(d) 内皮性囊肿。有证据（免疫组织化学和超微结构）表明假性囊肿和内皮性囊肿均为血管性囊肿的变体。肾上腺血管性囊肿占肾上腺囊肿的84%。它们在女性中更为常见，临床上表现为腹痛或为偶然发现。其影像学特征不具有特异性。大体上，两种类型的肾上腺血管性囊肿均有包膜。假性囊肿为单房性、厚壁，无内皮衬里，而内皮性囊肿为薄壁、多房性，内衬内皮。肾上腺血管性囊肿可能起源于先前存在的血管错构瘤。治疗的选择是手术切除。预后良好。
