Minor Salivary Gland Carcinoma Extending to Intracranial, Retroorbital and Sinonasal Cavity: Case Report

ABSTRACT

We report a case of huge minor salivary gland carcinoma extending to intracranial, retroorbital and sinonasal cavities. The patient was a 51-year-old man who had progressive nasal obstruction, decreased visual acuity and headache. Brain computed tomography and magnetic resonance image revealed a huge heterogeneous enhancing mass with extensive bony destruction originating from right maxillary sinus and both nasal cavities to the frontal base structures. The tumor mass was approached by a craniofacial route and subtotal removal was done because of its marked invasion of cavernous sinus, parasellar structures and hypothalamus. The histological diagnosis was minor salivary gland adenocarcinoma.
