Scapular Osteochondroma with Bursa Formation: A Rare Entity with Literature review

Abstract

Abstract:

Osteochondroma is the most frequent benign tumor of bone that occurs predominantly in the long bone, but can arise from any bone which is preformed from cartilage. We hereby report a very case of scapular osteochondroma with bursa formation along with rib erosion in 18-year old male who referred to CT & MRI Centre with winged scapula and limited range of motion of his right shoulder. Plain x-ray showed a bony outgrowth of scapula associated with a soft tissue lesion. CT scan confirmed an osteochondroma arising from the ventral surface of the right scapula associated with a large bursa formation and adjacent rib erosion. To best of authors’ knowledge, very few cases of osteochondroma of scapula with bursa formation and rib erosion have been reported in the literature so it highlights the importance of considering this rare entity in the differential diagnosis for any adolescent presenting with winging of scapula.

Key words: bursa formation, rib erosion, scapular osteochondroma, winged scapula.
