Abstract
- A 43-year-old female presented with persistent headache and dizziness which had first occurred two years earlier. The physical and neurological findings at admission were unremarkable, though plain radiography revealed the presence of a dense calcified mass in the left frontal area, and CT showed that a homogeneous high-density nodule was attached to the inner surface of the left frontal skull. The hard bony mass found and excised during surgery was shown at histopathologic examination to be a subdural osteoma. We describe the clinicopathologic findings of this entity and discuss the radiological features which suggest its subdural location.

Fig. 1 A 43-year-old woman with subdural osteoma. A. Radiograph of the left lateral skull depicts a radiopaque lesion (arrows) in the frontal area. B. CT scan reveals the presence of a lentiform ossified lesion (arrows) in the left frontal area (window width: 90; window level: 25). C. Bone window setting shows a lucent line (arrows) between the ossified lesion and the inner table of the skull (window width: 2000; window level: 200). D. Intraoperative radiograph depicts an ossified lesion (arrows) under the craniectomy site. E. Intraoperative photograph indicates that the lesion (arrows) is firmly attached to the reflected dura (arrowheads). F. Microscopically, the tumor consists of a well-formed mature lamellar bone beneath the fibrous membrane (dura mater) (arrows) (H & E staining, ×40).
