Huge Osteoma on Suboccipital Region: A Case Report

Abstract

Osteoma is the most common benign tumor in the craniofacial bone. We present a case of osteoma, a rare site in a patient with palpable mass on suboccipital area. A 54-year-old woman presented with palpable mass in the right occipital area. Brain computed tomography scan indicated that the mass was starting from the outer table of the occipital bone. The mass was separated well from the cortical bone. Histopathology report presented osteoma diagnosis composed of a compact bone. After the operation, the patient was discharged without any complications and follow-up was done for 8 years without incidences of recurrence. It is very rare for osteoma to occur in the occipital bone. We reported a case of a huge osteoma of the occipital bone that grew without invasion of the inner table of the cranial bone.
