Carcinomas of the hard or soft palate are known to spread perineurally along palatine branches of the maxillary nerve. Imaging of perineural tumor spread from the palate has been underemphasized in the imaging literature. We report the findings from eight patients in whom spread from primary cancers of the palate was seen along the palatine nerves. Indications of perineural spread include enlargement or excessive enhancement of a nerve, or abnormal density/signal intensity, enhancement, or widening of the pterygopalatine fossa, cavernous sinus, or Meckel's cave.
