This exhibit provides CT and radiographic examples of large, symptomatic torus palatinus, mandibularis, and maxillaris from sixteen separate patients, six of whom underwent surgical resection.  The imaging findings are correlated with photographs and pathologic specimens to establish a complete overview of this common clinical entity.

Autosomal dominant inheritance pattern of tori Anatomic location of tori and their prevalence across different ethnic groups Clinical presentation of symptomatic tori Imaging findings of tori, both CT and radiographic. Correlation of imaging findings with photographs and pathologic specimens  

Commonly encountered though rarely mentioned in the radiology literature, tori are a unique type of exostosis, which are inherited in an autosomal dominant fashion and occur in approximately 20% of Caucasians.  Symptomatic tori are often treated by oral surgeons and therefore radiologists have limited exposure to their diagnosis and management.  Familiarity with the imaging and pathology of this common entity will facilitate effective communication when faced with symptomatic tori.
