Hemangiomas are frequent benign hereditary vascular tumors. Intramuscular hemangiomas, a distinctive type of hemangioma occurring within the skeletal muscle, account for less than 1% of all hemangiomas. They occur more often in the trunk and extremity muscles, whereas the involvement of the temporal muscle is extremely rare. A 34-year-old man with a mass in his left temporal fossa was admitted. Computed tomographic scan showed no erosion of the bone, and magnetic resonance imaging revealed an ovoid mass within the temporal muscle. The lesion was surgically excised, and histopathologic examination confirmed the diagnosis of cavernous hemangioma. The patient was not able to lift his left eyebrow right after the surgery. Two months after the surgery, the patient recovered from paralysis, and there was no recurrence of tumor 12 months after the surgery. We report the 27th cavernous hemangioma case of the temporalis muscle. Care must be taken to avoid possible stretch injury to facial nerve branches while resecting these tumors.
血管瘤是常见的良性遗传性血管肿瘤。肌内血管瘤是一种发生于骨骼肌内的特殊类型血管瘤，占所有血管瘤的比例不到1%。其多发生于躯干和四肢肌肉，而颞肌受累极为罕见。一名34岁左侧颞窝有肿物的男性入院。计算机断层扫描显示骨质无侵蚀，磁共振成像显示颞肌内有一椭圆形肿物。病变经手术切除，组织病理学检查确诊为海绵状血管瘤。术后患者即刻无法抬起左眉。术后两个月，患者从麻痹中恢复，术后12个月肿瘤无复发。我们报道第27例颞肌海绵状血管瘤病例。切除这些肿瘤时必须小心避免对面神经分支造成可能的牵拉损伤。
