Giant Aneurysmal Bone Cyst of the Rib

Abstract

Aneurysmal bone cyst (ABC), especially in the ribs, is a rare disease, considering to be a benign lesion which occurs mostly in children and young adults. This case, however, concerns a 46-year-old female patient, with complaints of pain and palpable mass in the right thoracic wall, who was diagnosed to have ABC originating from the rib demonstrated by radiological examinations, aspiration biopsy, and histopathological verification. Surgical resection was performed to the lesion.
