Key Words: Trauma Pseudoarthrosis Synovial cyst
A traumatized 63-year-old man was managed with tube thoracostomy as he had a right-sided hemopneumothorax and multiple rib fractures. He had an uneventful outcome, however, he presented with a soft, painful swelling in the vicinity of his right scapula 8 weeks following his discharge. Chest X-ray showed apparent non-union 4-5-6-7th ribs on the right side. Computed tomography showed a right-sided cystic appearance (Fig. 1
). Histological and immunohistochemical examination revealed a cystic lesion of synovial nature (Fig. 2
).
