Falcotentorial plasmacytoma

Abstract

✓ Intracranial solitary plasmacytomas are extremely rare tumors and are often misdiagnosed preoperatively. The authors report the successful treatment of a patient who harbored such a tumor involving both the falx and tentorium; this is the second case reported. A 59-year-old woman suffered from a seizure disorder due to a falcotentorial lesion, which had been identified 3 years earlier and was thought at the time to be an en plaque meningioma. Most recently, the patient presented with symptoms of increased intracranial pressure and hemiparesis. Computerized tomography and magnetic resonance imaging of her head revealed progressive growth of the tumor. The patient underwent partial resection of the tumor and chemo- and radiation therapies. Intracranial plasmacytomas must always be included in a differential diagnosis because potential complete cure can be achieved using fairly conservative treatment modalities.
