Fibrous Dysplasia with Aneurysmal Bone Cyst Presenting as Painful Solitary Skull lesion

Abstract

We report a rare case of fibrous dysplasia with the development of a secondary aneurysmal bone cyst presenting as solitary tumor of calvarium. Although fibrous dysplasia with aneurysmal bone cyst is rare, it should be taken into account in differential diagnosis of the osteolytic solitary skull lesion.
