 First image Presented with pain in the buttoc Lytic expansile lesion of Ischium extending to inferior surface acetabulum. Treated by cutettage via a medial (Ludlov approach) and bone grafting. Two years later the patient was asymptomatic and the cyst consolidated. Benign cysts later become sclerotic as they heal especially if bone graft was used in treatment. Remaining lytic areas in the cyst can be a cause of concern, and may warrant rebiopsy as they may be a recurrentce of the tumour.
