Abstract

Aneurysmal bone cyst is a benign, locally aggressive, expansile cytic lesion. It is characterized by blood filled spaces separated by fibrous septae. The cystic spaces are lined by cells which morphologically, ultrastructurally and immunohistochemcally have features of fibroblat, myofibroblasts and histiocytes but NOT endothelium.

We report a very rare case of aneurysmal bone cyst involving the three bones of the skull vault-parietal & frontal with coronal suture.and temporoparietal joint.
