Giant Cell Tumor with Aneurysmal Bone Cyst Changes of Proximal Fibula in a Young Male - A Case Report

Abstract

Giant cell tumor (GCT) account around 5% of bone tumors with a slight female preponderance. We are presenting a case 32yr old gentleman, who presented with c/o swelling present on lateral aspect of proximal third of left leg for past one year and pain over the swelling for past 3 months with no significant history of trauma. X ray revealed solitary lytic lesion with thin rim of cortex over proximal fibula. MRI showed a lytic le-sion over sub articular area with internal septation having a “bubbly” appearance involving left fibula with mass effect on lateral tibial plateau. Intraoperatively tibia appears to be normal. Histopathological examination of the excised mass revealed giant cell tumor of proximal fibula with secondary aneurysmal bone cystic (ABC) changes with the margins free of tumor. Postoperatively, patient is pain free with loss of dorsiflexion of foot with loss of sensation over dorsum and he is put on regular follow up.
