Osteochondroma as a Cause of Scapular Winging In an Adolescent Girl- Case Report

Abstract

Introduction: Although long thoracic nerve palsy is the classical pathogenesis of winging scapula, it may also be caused by osteochondroma. We report a rare case of a scapular osteochondroma arising from the medial border and causing a pseudowinging of the scapula. Case presentation: 15 year old girl presented with progressive deformity and painless swelling in the medial aspect of scapula. Clinical examination showed bony hard swelling in the medial aspect of scapula and had full painless range of movement with grating sensation on extreme range of movement. Patient was investigated and underwent open surgical excision. A histopathology examination confirmed the clinical diagnosis of osteochondroma. A clinical examination three months later showed a painless full range of motion and absence of grating sensation and disappearance of deformity. Conclusion: osteochondroma should be considered in the differential diagnosis for any adolescent presents with a winging of the scapula.
