Abstract

Purpose: Aneurysmal bone cysts are benign bone lesions representing approximately 1% of all bone tumors. Lesions usually manifest in the first or second decade of life and are most frequently eccentrically located in the metaphysis of long tubular bones or in the axial skeleton. Etiologically lesions are considered as benign intra-osseous vascular malformations but can become locally aggressive, with significant extraosseous expansion. Conventional treatment protocols consisted of surgical curettage, with or without associated bone grafting. In some cases, the localization and extent of the cyst are such that operative treatment is extremely hazardous. Moreover surgical curettage is associated with high recurrence rates varying from 10 to 44%. We present a less invasive treatment option with fluoroscopy and conebeam-CT guided direct percutaneous sclerotherapy with intralesional absolute alcohol injections.
