A case of an idiopathic bone cavity is presented and discussed. The patient was a 54-year-old Japanese male with a history of stomach carcinoma operation and hospitalization two years ago. He was referred to the Department of Dental Radiology with a panoramic radiograph performed by the dentist. The panoramic radiograph demonstrated a well-defined elliptical radiolucent lesion near the right angle of the mandible, situated below the mandibular canal and slightly above the inferior border of the mandible. The patient stated that the lesion progressed asymptomatically without any sensation. From the lesion was indicated, the patient was greatly anxious about metastasis of stomach carcinoma to the mandible. To define the diagnosis of the lesion, intraoral radiography, extraoral radiography, tomography, and sialography were carried out. All results showed that the lesion was an idiopathic bone cavity without relationship to salivary gland tissue. No biopsy was carried out, but the lesion was diagnosed to be benign, and a metastatic carcinoma was ruled out.
