Abstract

We report a case of plexiform schwannoma located in the flexor muscles of the forearm in the absence of other signs of neurofibromatosis or schwannomatosis. Magnetic resonance examination revealed a multinodular irregular inhomogeneous mass. Some nodules displayed a peripheral, high intensity rim and a central low intensity (target sign) on T2-weighted images. Pre-operative diagnosis of the rare plexiform schwannoma may be possible with careful imaging examination for the target sign.

摘要

我们报告一例位于前臂屈肌的丛状神经鞘瘤，患者无神经纤维瘤病或神经鞘瘤病的其他体征。磁共振检查显示为多结节状不规则不均匀肿块。在T2加权图像上，一些结节表现为外周高信号环和中央低信号（靶征）。通过仔细的影像学检查观察靶征，术前有可能诊断出这种罕见的丛状神经鞘瘤。
