Intramuscular tumoral calcinosis near the arteriovenous fistula mimicking acute infection

Tumoral calcinosis is a kind of tumorous calcified masses, which may progress in patients with chronic renal failure. Uremic tumoral calcinosis in the brachioradialis muscle presented like acute infection of the arteriovenous fistula has not been previously reported. A 49-year-old man came to our hospital with a 9-year history of hemodialysis and secondary hyperparathyroidism. He had a huge painful mass in the left forearm at admission. The treatment was debridement and cytoreductive surgery accompanied by parathyroidectomy and medical management of calcium phosphate imbalance. After the comprehensive treatment, the patient recovered from his previously affected forearm. This is an enlightening case of intramuscular tumoral calcinosis mass that presented mimicking the infection of the arteriovenous fistula. Nephrologists and surgeons should pay attention to early diagnosis and proper management of the primary disease to master the indication and opportunity of resection.
