Imaging findings of intraosseous traumatic neuroma of the mandible

Abstract

© 2017, Japanese Society for Oral and Maxillofacial Radiology and Springer Japan. A traumatic neuroma is an uncommon pseudotumor associated with peripheral nerves and occurs following surgery or trauma. It mostly occurs in the extraosseous soft tissue; traumatic neuromas of intraosseous origin are extremely rare. We herein report an unusual case of an intraosseous traumatic neuroma associated with the inferior alveolar nerve that was incidentally found on a panoramic image. In this report, we place special emphasis on the imaging features of traumatic neuroma, including the computed tomography and magnetic resonance imaging findings.
