title: Ewing's sarcoma of the cranial vault: a case report.
abstract: Ewing's sarcoma is a malignant tumor that mainly affects young patients. It represents 10% of primary malignant tumors of the bone and 3% of malignant tumors of the child. Cranial localization is extremely rare representing less than 1% of all the localizations. We report a case of a 10-year-old girl who presented with an intracranial hypertension syndrome with left parietal mass of progressive installation. The X-ray skull showed a lytic lesion with irregular margins involving the left parietal bone. Brain magnetic resonance imaging revealed extensive parietal bone destruction involving both the inner and outer tables. The girl was operated in emergency. Histological examination concluded to Ewing's Sarcoma. The resection was incomplete (R1). The girl received induction's chemotherapy. The cerebral scanner evaluation showed no abnormalities. Then, she received consolidation's chemotherapy with concomitant local radiation therapy. Currently, the girl is in complete remission with a seven-month decline.
