Intermittent Axillary Nerve Palsy Caused by a Humeral Exostosis

We report an uncommon case of intermittent axillary nerve palsy caused by a humeral exostosis in an 11-year-old boy. After excision of the cartilagenous exostosis of the proximal end of the left humerus, the pre-operative symptoms of axillary nerve compression were alleviated.
