Masses of
developmental and genetic origin affecting the paediatric craniofacial skeleton. Torus palatinus (TP) in a 3-year-old girl who underwent imaging because of an indurated palpable midline mass of the hard palate increasing in size (a) after a fall occurring from a swing hanging on a tree two weeks earlier. Coronal low-dose CT image (bone window) (b) and three-dimensional CT VR reconstruction show a small midline spur/exostosis (arrow and circle). Characteristic aspect of a torus mandibularis (TM) (asterisks in d and e), of a TP (arrowheads in e and f) and of a torus maxillaris (TMax) (arrows in f) as seen in a young adult. It is worthwhile mentioning that TM and TMax are extremely rarely diagnosed in children

Mandibular tori, analogous to maxillary tori, are common benign outgrowths of bone from the inner surface of the mandible and are usually bilateral.
Clinical presentation
They are usually asymptomatic but may cause issues with eating and drinking.
Pathology
They are composed of compact bone, densely mineralized usually without medullary cavity, and arise from the inner surface of the mandible.
The cause of such bony outgrowths has not been established but a genetic component is thought likely.
Radiographic features
CT
Bony outgrowths from the inner aspect of the alveolar bone of the mandible above the origin of the mylohyoid muscle.
Treatment and prognosis
Mandibular tori are benign, slow growing and non-invasive. Removal is required only if they are symptomatic.
