A–E images: A 43-year-old female patient complained of right hand pain, tingling, numbness radiating to shoulder and weakness of thumb abduction. The patient underwent surgical release of flexor retinaculum 1 year ago. The complaints returned 3 months ago. By nerve conduction studies, there was severe partial axonal degeneration of right median nerve at the wrist. A Axial PD MR image shows soft tissue band (yellow arrow) seen at the operative bed causing flattening and compression of the median nerve at the level of carpometacarpal joint and head of metacarpal bone with subsequent proximal swelling, B T2-SPAIR image shows increased signal intensity of the MN (yellow arrow), C T2-weighted MR image shows flattening of the MN (yellow arrow) at the level of hamate, D ADC map shows low mean ADC value of MN at DRUJ (0.95 × 10–3 mm2/s), and E ADC map shows increase of mean ADC value at pisiform (1.4 × 10–3 mm2/s). These MRI features are consistent with recurrent carpal tunnel syndrome
