Intraneural ganglion cysts of the peripheral nerve in the upper extremity are uncommon and usually originate within the epineurium of the peripheral nerve. The current report discusses a 57-year-old woman with a neuropathic nodular mass on the thenar area of the left hand. Magnetic resonance images showed a lobulated, homogeneous mass of high signal intensity on T2-weighted images and low signal intensity with peripheral enhancement on T1-weighted images. Excisional biopsy and histopathologic examination confirmed an intraneural ganglion cyst of the digital nerve of the thumb. A successful result was obtained by surgical treatment, and there was no recurrence of abnormal sensation and paraesthesia during the 3-year follow-up period.
上肢周围神经内神经节囊肿不常见，通常起源于周围神经的神经外膜内。本报告讨论了一位 57 岁女性，左手大鱼际区有神经病理性结节性肿块。磁共振成像显示 T2 加权图像上呈分叶状、均匀的高信号强度肿块，T1 加权图像上呈低信号强度伴周围强化。切除活检和组织病理学检查证实为拇指指神经内神经节囊肿。手术治疗取得了良好的效果，在 3 年的随访期间，异常感觉和感觉异常没有复发。
