Abstract

Giant cell reparative granuloma (GCRG) is an uncommon non‑neoplastic reactive tumor which occurs almost exclusively within the mandible and maxilla. GCRG of the temporal bone is a rare condition. It has been found to affect predominantly adolescents and adults (age: 10‑25 years). We report a case of a 62‑year‑old male with GCRG of left temporal bone who presented to us with progressive left temporal swelling for 3 months. It was associated with hearing loss. There was no history of trauma. A non‑contrast computed tomography scan brain showed a locally destructive lesion involving squamous temporal bone closely related to the left temporal lobe and infratemporal fossa. Magnetic resonance imaging brain with contrast showed a hypointense lesion on T1 and with peripheral contrast enhancement after gadolinium injection. Patient underwent left temporal craniotomy with atticotomy, mastoidectomy, duraplasty, and opening of middle ear and temporomandibular joint. A bone graft was then taken from right iliac crest and used to repair the resulting defect. Final histopathology report confirmed GCRG. We discuss radiological and histopathological features of lesion in this case report.
