Vidian metastasis of adenoid cystic carcinoma.
Head and neck tumors may invade perineural space, especially the maxillary division of the trigeminal nerve and the pterygopalatine fossa (PPF). Computed tomography (CT) and magnetic resonance imaging (MRI) signs of perineural extension include essentially the obliteration of the PPF fatty content and the enlargement and erosion of neural foramina. We report a case of perividian metastasis studied with CT and MRI.
