Multiple calcifying lesions in the maxilla and mandible of a 4-year-old girl: report of a rare case and literature review

Calcifying lesions in the jaws are usually solitary and can be diagnosed by intraoral, panoramic, and conventional extraoral radiographs. It is extremely rare for these calcifying lesions to be multiple, unless they are associated with certain systematic diseases. Herein, we report a rare case of multiple odontomas in a 4-year-old girl. The lesions were scattered throughout both jaws on the panoramic image. The reconstructed CT image showed lesions in the left maxilla that occupied the sinus and affected the floor of the left orbit. The lesions in the mandible were widespread and extended to the tooth-bearing area. Enucleations of the maxillary parts were performed, and the pathological diagnosis was a mixture of complex and compound odontomas. The 3-year postoperative follow-up by panoramic imaging was uneventful. Preoperative CT was useful for the differential diagnosis by depicting the internal calcifying lesions and revealing the extent and complex relationships among the lesions.
