UNASSIGNED: Inflammatory @entity5 (IMTs) are rare. IMTs of the head and neck occur in all age groups, from neonates to old age, with the highest incidence occurring in childhood and early adulthood. An IMT has been defined as a histologically distinctive lesion of uncertain behavior. This article describes an unusual case of IMT mimicking @entity1546 in the mandible of a 42-year-old @entity1 . At first presentation, the @entity1 showed spontaneous @entity158 and percussion @entity158 at teeth #28 to 30, which continued after initial endodontic treatment. Panoramic radiography revealed a radiolucent lesion at the site. Cone-beam computed tomographic imaging showed @entity690 , suggesting an aggressive @entity5 requiring incisional biopsy. Histopathological examination indicated an IMT. The lesion was removed en bloc under general anesthesia, and the @entity1 manifested no clinical evidence of recurrence for 24  months. Lesions of nonendodontic origin should be included in the differential diagnosis of @entity1546 . Every available diagnostic tool should be used to confirm the diagnosis. Cone-beam computed tomographic imaging is very helpful for differential diagnosis in IMTs mimicking @entity1546 .
