Ponticulus Posticus is a Frequent Radiographic Finding on Lateral Cephalograms in Nevoid Basal Cell Carcinoma Syndrome (Gorlin–Goltz Syndrome)

Cropped images of lateral cephalograms of patients with nevoid basal cell carcinoma syndrome. A: Atlas region of a three-year old girl with initial superior spicule but no signs of bridging. B: The same patient at the age of 20 years with completely developed ponticulus posticus (arrow). Note associated pathology of the maxillary sinus. C: Image from a 12-year-old girl with radiopaque arch-like structure probably arising from the upper region of the atlas (arrow). D: Ponticulus posticus in a 12-year-old boy. Note osseous pathology of the mandible. E: Marked bridging in a 27-year-old male. Parts C-D are mirrored in order to align the facial aspect of all figures to the left side.
