title: Panniculitis ossificans in a patient with excessive push-ups: imaging findings with histological correlation.
abstract: Panniculitis ossificans arising symmetrically in the subcutaneous layer of both shoulders is rare. A case of a 27-year-old man with recent history of doing excessive push-ups is reported. According to the patient's statement, there is no notable history of alcoholism, major trauma, or injection of nonsteroidal anti-inflammatory drugs. Computed tomography of both shoulders showed multiple subcutaneous masses with calcified/ossified rims and central fatty content. Histological examination confirmed the diagnosis of panniculitis ossificans, showing subcutaneous fat necrosis associated with osteoid material.
