Histologically proven KCOT. a OPT. Axial CT image with bone window (b) and soft tissue window (c). Multilocular well-defined radiolucent lesion (asterisk) with thin, sclerotic borders, cortical scalloping (arrow) and resorption of teeth roots. Cyst contents with attenuation values of 40–50 HU mimicking solid tissue. d Posterior view of a 3D reconstruction showing the relationship between the keratocyst (blue), the partially resorbed teeth (green) and the mandibular canal (red). The mandibular canal can be seen only in the posterior mandible, as it is encased by the keratocyst
