Gliosarcoma with long progression free survival: A case report and literature review

Gliosarcoma (GS) is a primary rare malignant brain tumor that accounts 4% of all high-grade glial tumor of the brain.

We present a 45-year-old female admitted to our center with progressive headache since 1 month ago concomitant with nausea and emesis and generalized weakness. Imaging revealed a large solid mass with well-defined margin and some cystic portions that enhanced brightly with contrast. We decided to operate the patient via right parietal craniotomy and we totally resected all visible portions of the mass, as en bloc resection. The histopathological report of the mass was GS. We are following the patient up to now, for about 50 months, and she is good without any compliant or neurologic deficit. All follow-up magnetic resonance imaging (MRI) did not show any tumor recurrence.

Aiming to achieve longer progression-free survival in cases of GS, we recommend resecting all portions of the mass as much as possible, so named en bloc resection, and then refer the patients for appropriate and timely chemoradiotherapy.
