This paper is about a primary extracranial meningioma case of a 40-year-old male patient who presented with a complaint of a rapidly growing painless stiff mass located in his left thigh. The magnetic resonance imaging examination revealed that the lesion was well-circumscribed and with isosignal intensity to muscle on T1-weighted images and with a relatively hiperintense on T2-weighted images. The histopathological analysis of the specimens both from the incisional biopsy and the excisional surgery were typical of meningioma showing spindle cell proliferation with a whirling pattern. Although extracranial meningiomas are very rare, it should be considered in the differential diagnosis of a spindle cell neoplasm.
本文报道了一例40岁男性原发性颅外脑膜瘤病例，患者主诉左大腿有一个快速生长的无痛性硬结肿块。磁共振成像检查显示，该病变边界清晰，在T1加权图像上与肌肉信号强度相同，在T2加权图像上相对高信号。切开活检和切除手术标本的组织病理学分析均为典型的脑膜瘤，表现为梭形细胞增殖并呈漩涡状。尽管颅外脑膜瘤非常罕见，但在梭形细胞瘤的鉴别诊断中应予以考虑。
