Aneurysmal Bone Cyst Of Pubic Ramus: A Rare Entity

INTRODUCTION: Aneurysmal bone cyst is an expansile, lytic, multiloculated, fluid filled cavities which usually occurs in the metaphysis of the long bones. ABC of the pubic ramus is a rare entity.. CASE REPORT: We present a case of a 21 year old male who presented with a swelling of the right inguinal region which was gradually progressive. Radiologically, there was a lytic expansile lesion of the superior pubic ramus. A contrast computed tomography revealed multiloculated cystic cavities and histopathology confirmed the diagnosis of ABC. Surgical excision of the complete tumor by anterior approach was done. Till date (2 years since surgery) patient has no recurrence. CONCLUSION: ABC of pubic ramus is a rare entity and other differentials should always be kept in mind with confirmation of diagnosis by histopathology. Treatment with surgical curettage and bone grafting the defect is curative in selective cases but in this case due to size and location excision is the choice of treatment.
