원시성 신경외배엽 종양의 전산화 단층 촬영 및 자기 공명 영상 소견 = CT and MR Findings of Primitive Neuroectodermal Tumor

다국어 초록 (Multilingual Abstract)

Cerebral primitive neuroectodermal tumor (PNET) is a neoplasm of children and young individuals that occurs predominantly in the supratentorial compartment. It is a diagnosed as a genetic term for cerebellar medulloblastomas and for neoplasm which are morphologically indistinguishable from the medulloblastoma but are located at other sites in the CNS. In this report, we retrospectively reviewed and analyzed 7CT and 2 MR findings in 7 patients with pathologically-proven PNET or radiologically characteristic PNET findings. The most characteristic features of the PNETs was a well-defined oval or round large mass with/without intratumoral calcification and hemorrhage in the cerebral hemisphere, especially in the parietal and frontal lobe. There was only minimal surrounding edema. The CT and MR findings demonstrated solid portion and cystic area but mainly enhanced in the solid portion.
