Neurothekeomas are rare benign tumors of soft tissue that are of presumed neural sheath origin. This report describes the magnetic resonance imaging and computed tomography features of a neurothekeoma in the left forearm of a 38-year-old woman with a 2-year history of a painful mass. Magnetic resonance imaging showed a smooth-bordered ovoid lesion within the inner portion of the extensor digitorum muscle with a Hounsfield number of 15. The lesion had intermediate signal on T1-weighted images, high signal on T2-weighted images, and mild to moderate heterogeneous gadolinium contrast enhancement.
神经鞘黏液瘤是一种罕见的软组织良性肿瘤，推测起源于神经鞘。本报告描述了一名38岁女性左前臂神经鞘黏液瘤的磁共振成像和计算机断层扫描特征，该患者有一个疼痛性肿块，病史2年。磁共振成像显示在指伸肌内部有一个边界光滑的椭圆形病变，亨氏单位为15。该病变在T1加权图像上呈中等信号，在T2加权图像上呈高信号，钆对比剂增强呈轻度至中度不均匀强化。
