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 tumour of the jaw with a characteristic histological appearance. We describe here its appearance on computed tomography (an expanding, multilocular lesion that is thinning both plates of the mandible, is well-defined and contains scattered radio-opaque areas) and magnetic resonance imaging (predominantly hypointense on T1-weighted images and of mixed hyperintensity on T2-weighted images; the extent of the tumour including involvement of the mandibular canal was clear).
