Transcatheter embolisation therapy of an ischial aneurysmal bone cyst

Aneurysmal bone cysts are uncommon, benign but locally aggressive bone tumours of the young. They are usually treated by resection, or by curettage followed by bone grafting, or by radiotherapy. We report the successful transcatheter devascularisation of an aneurysmal bone cyst of the ischium which obviated the need for surgery or radiotherapy. Transcatheter embolisation therapy has previously been used to control bleeding and in the preparation of malignant and benign tumours for operative removal.
