Suprascapular nerve palsy with solitary atrophy of the infraspinatus muscle which was caused by ganglion is presented. The patient was a 30-year-old male nailer. In operative findings, the cyst was spindle-shaped, extending itself as if it were enveloping the nerve, and had no pedicle with the capsule or the adjacent tissue. It is very likely from the clinical findings that the ganglion was of intraneural origin, perhaps in the epineurium of the inferior branch of the suprascapular nerve. No such case has been reported previously.
