We report a case of a 33 year-old-man who presented with a left frontal intracerebral abscess which was associated with a frontoethmoidal orbital osteoma. Erosion of the frontobasal dura mater by the expanding osteoma caused this rare presentation. The patient underwent evacuation of the abscess followed by resection of the osteoma. Although osteomas tend to remain quiscent in most of the patients, they rarely become symptomatic to such an extent that, as in the present case, they deserve to be considered in the differential diagnosis of intracerebral abscesses.
