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.

Osteoid osteoma is very rarely located in the patella, and can represent a significant diagnostic challenge, resulting in a delay of treatment. Patients with osteoid osteoma of the patella often present with knee pain that is also a typical symptom of trauma or of other diseases such as arthritis, which are much more common than osteoid osteoma. We present two young male patients diagnosed with osteoid osteoma of the patella. Each of these patients had a history of intense knee pain; however, accurate diagnosis of osteoid osteoma in the patella had been delayed for more than one year. Computed tomography (CT) scans or magnetic resonance imaging (MRI) showed a circumscribed lesion of the patella in both patients, whereas X-ray examination (posteroanterior projection) was not able to detect the tumor. Different surgical procedures were performed in these patients for resection of the tumors, and the pathology findings confirmed the diagnosis of osteoid osteoma. Both patients recovered completely from surgery.
