Abstract:
The common variant of angiofibromas of head and neck region is juvenile nasopharyngeal angiofibroma (JNA). However extranasopharyngeal angiofibromas (ENAF) occurs very rarely at any age in either sex, and they differ from classical JNA in incidence, clinical and radiological presentation. They form the differential diagnosis for any mass nose or nasal polyp. We present a case of recurrent angiofibroma of ethmoid region presented with recurrent lesion with bilateral proptosis and bossing of forehead. MRI showed involvement of bilateral nasal cavities, ethmoids and frontal sinuses with erosions of ethmoid roof and posterior table of frontal sinuses. Entire mass was excised by craniofacial resection which was histopathologically confirmed as Angiofibroma.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
