Objectives/Interrogation: In our department for hand surgery we saw a 49 year old man who had been suffering from a weakness while spreading his small and ring finger for almost three months. No loss of sensation or dysesthesia had occurred. He had first presented himself to a neurologist who excluded pathologies of his cervical spine by an MRI and a CT scan.

Methods: During our clinical examination we saw an atrophy of his interosseous muscles of the fourth and fifth finger along with a weakness in spreading these fingers. He also brought an MRI which showed a cyst of unclear origin.

Because of the clinical findings we were sure that there was a pathology compromising the function of the distal ramus profundus of the ulnar nerve. That's why we saw the indication to explore the nerve in the OR.

During the surgery we saw an intraneural ganglion of the n. ulnaris and removed it.

Results and Conclusions: Intraneural ganglia of the distal ulnar nerve are a rare finding and can mostly be diagnosed by a detailed clinical examination.

We saw our patient again after three and six months. He has fully recovered the function of the hand and is again able to play the piano.
