DOI : 10.5606/tftrd.2026.16727 The trifid median nerve is an anatomical variation that is rarely observed in the general population. With variations, persistent median artery and persistent median vein may also be encountered. These variations are detected incidentally during diagnostic evaluations. In our case, a trifid median nerve was found in a 64-year-old female who was diagnosed with bilateral carpal tunnel syndrome as a result of electroneuromyography results and clinical evaluation. Identification of variations of the median nerve prior to injection and surgical intervention is important to reduce the risk of complications.
