Anomalous muscles are infrequently encountered in carpal tunnel surgery. They are challenging to identify and may mislead the surgeon by obscuring normal anatomy. Hence knowledge of their presence is essential. We report two cases of anomalous muscle encountered in the carpal tunnel during surgery. First case consisted of an anomalous muscle seen in carpal tunnel release surgery. The muscle had proximal tendinous origin at wrist and distal tendinous insertion on index finger. In the second case, we incidentally encountered an anomalous muscle, which originated from the distal end of radius, travelled through the carpal tunnel and fused with the flexor digitorum superficialis of the small finger. Through this case report we have discussed the current concepts regarding anomalous muscle in the carpal tunnel and its management.
