Abstract

Tumoral calcinosis is a benign condition characterized by periarticular calcified lesions that is frequently observed in patients with chronic renal failure. Tumoral calcinosis often presents with subcutaneous masses and joint swelling. We present a case of tumoral calcinosis with dramatically increased ¹⁸F-fluoro-2-deoxy-d-glucose (¹⁸F-FDG) uptake on positron emission tomography/computed tomography (PET/CT) that mimicked lymphoma or lymph node metastases.

Keywords: 18F-Fludeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT); chronic renal failure; tumoral calcinosis.
