CTICasesTumoral Calcinosis of the Scapular Region
Imaging findings
Chest radiograph reveals a large, lobulated, densely calcified soft tissue mass near the inferior portion of the left scapula, which does not appear to arise from or involve the underlying bone. On chest CT, the mass is confirmed to reside within the muscles surrounding the inferior scapula. Additional findings include a calcified, porcelain-like left atrium and generalized osteopenia.
Key takeaways
Tumoral calcinosis is a benign condition characterized by the deposition of calcium phosphate crystals in periarticular soft tissues, commonly seen in patients with end-stage renal disease on hemodialysis. Surgical excision is indicated if the lesions cause significant pain, limitation of motion, or infection.
