MR demonstration of a persistent median artery in carpal tunnel syndrome.
The median artery of the forearm appears early in embryological development and normally involutes before birth. In rare cases, it persists into adult life. Although usually asymptomatic, it can be a cause for carpal tunnel syndrome (CTS). This report describes the MR appearance of a persistent median artery in a patient with CTS. The symptoms were relieved after resection of the aberrant vessel.
