The case of a patient with a 2-day history of symptoms suggesting acute carpal tunnel syndrome is presented. However, an urgent electroneurographic examination revealed median nerve compression at the forearm and magnetic resonance imaging confirmed compression by a mass proximal to the carpal tunnel. Surgical exploration showed a recently thrombosed aneurysm of an epineural vessel. Histological and, later, general and angiological investigations could not reveal the underlying cause of this aneurysm. Preoperative electrodiagnostic examination is recommended in acute peripheral nerve compression to prevent decompression at an incorrect site. If atypical nerve compression is suspected, magnetic resonance imaging may be indicated to detect localized nerve compression and its underlying cause.
本文介绍了一例有2天症状提示急性腕管综合征的患者病例。然而，紧急神经电生理检查显示正中神经在前臂受压，磁共振成像证实腕管近端有肿物压迫。手术探查发现一条神经外膜血管近期血栓形成的动脉瘤。组织学检查以及后来的全身和血管学检查均未发现该动脉瘤的潜在病因。对于急性周围神经受压，建议进行术前电诊断检查，以防止在错误部位进行减压。如果怀疑有非典型神经受压，可能需要进行磁共振成像检查以检测局部神经受压及其潜在病因。
