A rare form of solitary osteocartilaginous exostosis from anterior iliac spine: report of two cases

Abstract

Occurrence of exostosis from the metaphyseal regions of long bones and sometimes from the flat bones is well known. In the pelvis these lesions are almost invariably of the sessile variety. Tubular exostosis from the anterior iliac spine has not been reported in the literature. The 2 cases that attracted our attention because of pressure on neurovascular bundles are exhibited to put on record the occurrence of this rare form of exostosis.
