Desmoid Tumor Causing Shoulder Pain in an Adolescent Male

A 17-year-old adolescent boy was referred by an orthopaedic physician to physical therapy for chronic left shoulder pain and a clinical diagnosis of labral tear. The physician ordered current radiographs, which were noncontributory. Findings during physical therapy examination warranted referral back to the physician, with a request for magnetic resonance imaging. Magnetic resonance imaging revealed a soft tissue abnormality in the infraclavicular and subcoracoid spaces. The patient was referred to orthopaedic oncology, where biopsy confirmed a desmoid tumor. .
