Superficial radial nerve compression caused by a parosteal lipoma of proximal radius: a case report.
The superficial radial nerve might be compressed or injured at various anatomical sites along its course in the forearm. Most of the superficial radial nerve neuropathy are caused by pathological lesions such as trauma, a mass or tight band at the distal third of the forearm. Wartenberg's syndrome is the most common cause of sensory radial entrapment at the distal forearm. Compression of superficial radial nerve occurring at the proximal third of forearm is unusual. We present a rare case of superficial radial nerve compression due to a parosteal lipoma of proximal radius. Results of complete physical and radiological examinations are also presented. Surgical intervention of the tumour mass was performed for nerve decompression. The patient reported total relief of the neurological symptom post-operatively. This rare case demonstrates the unique characteristics of parosteal lipoma with unusual superficial radial nerve neuropathy at the proximal radius. This report reminds us that there is the possibility of superficial nerve compression caused by tumour mass over the proximal third of forearm.
