영상소견에서 뇌수막종으로 오인하였던 유잉육종: 증례 보고 = Ewing's Sarcoma Mimicking a Meningioma in Radiological Findings: A Case Report

국문 초록 (Abstract)

유잉육종은 드물게 발생하는 골종양의 일종으로 두부에서 발생하는 유잉육종은 더욱 드물어서 전체 유잉육종의 1%정도만을 차지한다(1). 두부에서 발생하는 유잉육종의 경우 방사선 소견상 악성골종양의 형태를 보이면서 심한 경우 두개내로 침범하는 것이 일반적이다. 저자들은 18세 남성에서 방사선 소견상 뇌수막종으로 생각하였으나 병리조직학적으로 유잉육종으로 진단된 1예를 경험하여 CT, MRI 및 혈관조영술 소견을 보고한다.

다국어 초록 (Multilingual Abstract)

Ewing's sarcoma is an uncommon primary bone tumor. Primary Ewing's sarcoma of the cranium is extremely rare and constitutes only 1% of all Ewing's sarcoma cases. Usually, primary Ewing's sarcoma of the carnium manifests as an expansile osteolytic malignant bone tumor with or without intracranial extension. We report here the radiological findings of a case of Ewing's sarcoma mimicking a meningioma in an 18-year-old man.
