Angioleiomyoma (vascular leiomyomas, angiomyoma) is a rare, benign soft tissue tumor which consists of a mixture of well-differentiated smooth muscle cells and thick-walled vessels. Here we report a case of angioleiomyoma in the sellar region, which is the first case report of angioleiomyoma at this anatomical location.
A 53-year-old man was admitted with a medical history of three months episodic headache and one month visual deterioration, both of which progressed gradually. The neurological examination showed nothing remarkable except a slightly decreased adrenocorticotrophic hormone (ACTH) level. Preoperative magnetic resonance imaging revealed a pituitary apoplexy. Gross total resection of the tumor was then performed.
Histological and immunohistochemical studies showed a typical microscopic appearance of an angioleiomyoma present in a rather uncommon place. The pertinent literature regarding the features of this tumor was reviewed and discussed.
Intracranial angioleiomyoma is a benign soft tissue tumor with excellent prognosis. Early diagnosis of this tumor is difficult.
血管平滑肌瘤（血管性平滑肌瘤、血管肌瘤）是一种罕见的良性软组织肿瘤，由分化良好的平滑肌细胞和厚壁血管混合组成。在此，我们报告一例鞍区血管平滑肌瘤病例，这是该解剖部位血管平滑肌瘤的首例病例报告。
一名53岁男性因有三个月发作性头痛病史及一个月视力减退病史入院，二者均逐渐进展。神经系统检查除促肾上腺皮质激素（ACTH）水平略有下降外无明显异常。术前磁共振成像显示垂体卒中。随后对肿瘤进行了全切除。
组织学和免疫组化研究显示，在一个相当不常见的部位存在典型的血管平滑肌瘤微观表现。对有关该肿瘤特征的相关文献进行了回顾和讨论。
颅内血管平滑肌瘤是一种预后良好的良性软组织肿瘤。该肿瘤早期诊断困难。
