Value of computed tomography and magnetic resonance imaging in the treatment of a calcifying epithelial odontogenic (Pindborg) tumour

The calcifying epithelial odontogenic (Pindborg) tumour is a rare primary t umour of the jaw with a characteristic histological appearance. We describe here its appearance on computed tomography tan expanding, multilocular les ion that is thinning both plates of the mandible, is well-defined and conta ins scattered radio-opaque areas) and magnetic resonance imaging (predomina ntly hypointense on T1-weighted images and of mixed hyperintensity on T2-we ighted images; the extent of the tumour including involvement of the mandib ular canal was clear).
