Abstract: | We report a case of a 69-year-old male who presented with pain, weakness, and clumsiness of his right hand. Initial evaluation
suggested possible neoplastic process affecting his cervical spine, which was fortunately ruled out by bone biopsy. Subsequent
electrodiagnostic studies and magnetic resonance imaging confirmed a lesion of the deep ulnar motor branch. Exploration of
Guyon’s canal was performed, and an intraneural ganglion involving the deep motor branch of the ulnar nerve was found and
excised. Despite more than 14 months of symptomatic duration, the patient made a near-complete recovery with virtually no
functional limitations. This provides supporting evidence for a functional benefit of intraneural ganglion excision and nerve
decompression even in cases of chronic muscle atrophy. |
