title: Sinonasal Adenoid Cystic Carcinoma with Intracranial Invasion and Perineural Spread: A Case Report and Review of the Literature.
abstract: We present the case of a 51-year-old patient with sinonasal adenoid cystic carcinoma (SACC). Computed tomography (CT) and magnetic resonance imaging (MRI) exams revealed an expansive process in the right nostril accompanied with perineural spread and invasion to the floor of the middle cranial fossa. Due to the size of the tumor and brain involvement, the Head and Neck Tumor Board (HNTB) recommended radiochemotherapy treatment to decrease the size of the lesion. Presently, the patient is undergoing treatment without major complications.
