A lingual mandibular bone cavity is an asymptomatic bone defect, which first described by Stafne in 1942. It appears as a well-circumscribed round or oval unilocular radiolucent lesion of the mandibular angle. The peak incidence is in the fifth and sixth decades of life. A well-defined radiolucent area was detected in the left posterior region of the mandible below the mandibular canal on an initial radiographic examination of a 9 -year-old boy at his dental clinic. Two years later, the radiolucent area had expanded on a follow-up radiographic examination. He was referred to our clinic by his dentist for further diagnosis and therapy. A computed tomographic (CT) scan was performed for definitive diagnosis of the lesion. The CT images revealed a lingual cortical bone defect. Therefore, the final diagnosis was a lingual mandibular bone cavity. The patient and his family were informed about the lesion and he was scheduled for follow-up at his dentist’s clinic. After 9 years’ follow-up, there was no radiographic progression.
