title: Lenticular lesions: not always an epidural hematoma.
abstract: Ewing's sarcoma is a tumor of the bone, which occurs most often in the diaphysis of long and flat bone. The most common sites of metastasis are the lungs and bones. Less frequently, the primary site is an intracranial or pelvic lesion (either as a soft tissue or a bone lesion). We report a case of a 16-year-old female with an extraosseous intracranial lesion, who presented with a history of minor trauma, unilateral facial swelling, and head pain. Though head computed tomography scan showed a lesion consistent with an epidural hematoma, further exploration revealed Ewing's sarcoma.
