Imaging of perineural tumor spread from palatal carcinoma

Department of Diagnostic Radiology, The University of Texas M. D. Anderson Cancer Center, Houston 77030, USA.
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.
