Percutaneous sclerotherapy for treatment of tumoral calcinosis

Massive tumoral calcinosis developed in a 29-year-old woman with type 1 diabetes and failed pancreas and kidney transplant on peritoneal dialysis. The patient had a symptomatic calcified, fluid-filled posterior thigh mass. After percutaneous drainage of 260 mL of milky fluid, she had rapid recurrence of the collection. She underwent catheter-based sclerotherapy first with 110 mL of povidone-iodine followed 2 days later by 40 mL of 3% sodium tetradecyl sulfate foam. At 5.5 months after the procedure, the patient remained asymptomatic, and computed tomography imaging showed complete resolution of the collection.
