Popis: Cases of carpal tunnel syndrome (CTS) secondary to ganglion cysts are sparse in the literature. The purpose of this case report is to demonstrate clinical and magnetic resonance imaging (MRI) findings of CTS secondary to an intra-tunnel ganglion, with denervation of the abductor pollicis brevis muscle (APB). A 42-year-old female presented with worsening pain, numbness, and tingling in the right hand of several months duration. Median sensory and motor latencies were consistent with CTS. MRI revealed a cystic mass within the carpal tunnel, which displaced and compressed the median nerve. Additionally, homogenous high signal intensity within the APB was detected, consistent with acute denervation. The diagnosis of CTS secondary to ganglion cyst was confirmed intraoperatively, with median nerve decompression and cyst removal.
