A case of isolated thenar numbness, with an associated painful palmar wrist mass is presented. At operation, a palmar wrist ganglion compressing the palmar cutaneous branch of the median nerve was encountered. After ganglion excision the numbness in the palm was relieved, and there was no recurrence at 6 years follow-up.
