Case with osteosclerosis. A 72-year-old male with a history of denosumab use for bone metastasis from bile duct cancer. Although he underwent extraction of the right mandibular second premolar at a dental clinic after a 2-month hiatus from medication, he was referred to our hospital due to treatment for bone exposure. (A, B) CT images (bone mode) showing an increase in CT values in the mandibular trabecular bone on both sides as well as the extraction socket of the right mandibular second premolar (ellipses). (C) Panoramic X-ray image revealing increased radiopacity in the mandibular trabecular bone on both sides. (D, E) T1-weighted MR image and T2-weighted fat-suppressed MR image demonstrate a sclerotic area in the same region, and the bone marrow signal in that area shows low signal intensity (ellipses).
