摘要

背景:眼眶平滑肌瘤是一种少见的眼眶平滑肌良性肿瘤,位于眼眶内或眼眶外。患这种肿瘤的男性是女性的两倍,平均年龄为30岁。病例描述:一名38岁女性,表现为眼球突出:轴突,无搏动,无痛,不复位,III级,伴动眼力损害,伴患侧视力下降,AV值为03/10,眼底:I级乳头水肿。计算机断层扫描显示一个孤立的组织肿块,局限良好,被包裹,通常均匀,注射造影剂后均匀增强。磁共振示圆形均匀病灶,T1等影,T2高影,注射钆后呈均匀强化。提示眶内海绵状血管瘤。患者通过额下入路行手术,并进行了宏观完全切除。组织病理学检查为眼眶平滑肌瘤。结论:眼眶平滑肌瘤虽罕见,但在眼眶肿瘤的鉴别诊断中应予以重视。

Orbital leiomyoma mimicking a cavernous hemangioma.

Background: Orbital leiomyoma is a rare benign tumor of the smooth muscles of the orbit with intraconal or extraconal location. The tumor affects twice as many men as women, with an average age of 30 years.

Case description: A 38-year-old female presented with proptosis: Axile, nonpulsatile, painless, nonreducible, Grade III, with impairment of oculomotricity, associated with a decrease in visual acuity on the affected side with an AV at 03/10, and fundus: Grade I papilledema. The computed tomography scan showed a solitary, tissue mass, well-limited, encapsulated, and usually homogeneous, with homogeneous enhancement after contrast injection. The magnetic resonance imaging showed a rounded, homogeneous lesion, isointense on T1 and hyperintense on T2, with homogeneous enhancement after gadolinium injection. Suggestive of an intraorbital cavernous hemangioma. The patient underwent surgery via a subfrontal approach, with macroscopically complete resection. Histopathological examination was in favor of an orbital leiomyoma.

Conclusion: Although very rare, orbital leiomyoma should be considered in the differential diagnosis of patients with orbital tumors.
