Aneurysmal bone cyst of the paranasal sinuses: A rare entity

Abstract

Aneurysmal bone cysts are vascular tumors that cause expansion and erosion of bone. We present this rare entity involving maxillary, ethmoid and frontal sinuses along with orbit. Computed tomography and histopathology showed typical features of aneurysmal bone cyst. We discuss clinical, radiological and histological details along with endoscopic management and literature review. The rarity of tumor makes this case interesting for head and neck surgeons.
