Soft tissue perineurioma is an uncommon benign peripheral nerve sheath tumor, although it is the most common subtype of perineuriomas. We present a case of soft tissue perineurioma in the left groin of a 48-year-old man. Precontrast computed tomography showed a homogeneous hypodense mass that showed faint enhancement. The mass appeared with hypointensity on T1-weighted magnetic resonance (MR) images and heterogeneous hyperintensity on T2-weighted MR images. Slight contrast uptake was noted on enhanced T1-weighted MR images with fat suppression. Although these CT and MR imaging findings were nonspecific, the overall imaging features are similar to those of schwannomas.
软组织束状神经瘤是一种罕见的良性周围神经鞘瘤，尽管它是束状神经瘤最常见的亚型。我们报告一例48岁男性左侧腹股沟区的软组织束状神经瘤病例。平扫计算机断层扫描显示一个均匀的低密度肿块，有轻度强化。该肿块在T1加权磁共振（MR）图像上呈低信号，在T2加权MR图像上呈不均匀高信号。在脂肪抑制的增强T1加权MR图像上可见轻微的对比剂摄取。尽管这些CT和MR成像表现不具有特异性，但总体成像特征与神经鞘瘤相似。
