Tumoral calcinosis is a rare disorder manifested by a large calcific mass, and associated peripheral nerve damage has been described previously in only one literature. We will report on an axillary nerve palsy caused by periarticular tumoral calcinosis in a patient undergoing hemodialysis.
The patient presented himself with a painful mass in the left shoulder, and weakness in joint elevation, which we diagnosed as an axillary nerve palsy. The patient's calcium-phosphorus product in the serum was elevated. Radiographic appearances of the mass was like an amorphous lobulated calcification. The palsy was diagnosed as being caused by the mass, and was treated operatively. The axillary nerve palsy was compressed by the mass, tumoral calcinosis, then the mass was resected. Postoperatively, the nerve function was recovered. The resected mass comprised of a thick connective tissue septa and cavities filled with a dense milky substance.
It is important to recognize that tumoral calcinosis may cause a nerve palsy located adjacent to it.
