A case of bilateral carpal tunnel syndrome with palmaris longus and FDS anomalies.

We report a case of bilateral carpal tunnel syndrome due to two distinct muscular anomalies coexisting with trigger finger deformity. Many muscular anomalies in association with carpal tunnel syndrome have been described so far. But such a unique case of bilateral carpal tunnel syndrome with two different muscular anomalies, flexor digitorum superficialis anomaly on one side and palmaris longus anomaly on the other side has not been described. Even rare, muscular anomalies should be considered in the aetiology of carpal tunnel syndrome.
