Kokubo R, Kim K, Isu T, Morimoto D, Kobayashi S and Morita A

This patient with carpal tunnel syndrome presented with a rare branch of the palmar cutaneous branch of the median nerve. The branch diverged from the radial side in the carpal tunnel and immediately penetrated the flexor retinaculum. Upon stimulation of the nerve, numbness radiated to the thenar area without muscle contraction.
