Abstract

|
Giant cell reparative granuloma (GCRG) is a rare benign bone disease of unknown causes. Trauma is a suspected cause or contributor to the onset of GCRG, of which only a few cases have been reported worldwide. We report a case of temporal bone GCRG in a 4-month-old male newborn, who was born at full term via spontaneous vaginal delivery with recent presentation of right facial palsy. He had a right temporo-occipital craniectomy due to GCRG 1 month earlier. There had been no history of trauma. During the workup of the facial palsy complaint, we identified a lobulated mass in the right temporal bone by computed tomography and magnetic resonance imaging. The mass was mainly in the petrous portion of the temporal bone with extracranial extension through the occipital bone. This was consistent with a GCRG recurrence. The mass was removed via the transcrusal approach, and the final histopathology report confirmed it as recurrent GCRG
