Gliosarcoma associated with a huge cyst--case report.
A 55-year-old female presented with a unique case of gliosarcoma with a huge cystic component manifesting as loss of consciousness, left-sided hemiparesis, and anisocoria. Computed tomography demonstrated a large cyst in the right frontal lobe, and enhancement of the mural nodule after administration of contrast medium. Emergent operation was performed. Xanthochromic fluid was aspirated, and the tumor was resected. The histological diagnosis was gliosarcoma based on the presence of gliomatous and sarcomatous components. She underwent a second operation because of tumor regrowth 3 weeks after the first operation. The postoperative course was satisfactory during radiation therapy with 60 Gy and chemotherapy. The diagnosis of gliosarcoma was difficult to make preoperatively because of the neuroradiological findings similar to low-grade gliomas. Gliosarcoma should be included in the differential diagnosis of huge cystic tumors.
