Dysembryoplastic Neuroepithelial Tumor

摘要: Overtreatment by radiotherapy and/or chemotherapy for central nervous system tumors in infancy and childhood may be deleterious, so the recognition of surgically curable clinicopathological entities is mandatory. The dysembryoplastic neuroepithelial tumor a complex multinodular lesion consisting glial nodules, associated with specific glioneuronal element focal cortical dysplasia, occurring young patients presenting intractable, mostly partial, seizures without neurological deterioration. We report on 14 patients; 9 were from series 600 pediatric intracranial studied at single institution 1988 to 1993, 5 referred other hospitals. Six frontal, six temporal, one was parietal, occipitoparietal. Computed tomographic scans disclosed hypodense lesions cystic appearances 4 slight postcontrast enhancements only 2 patients, whereas magnetic resonance imaging, available 7 showed hypointense T1-weighted images hyperintense T2-weighted images. Deformities overlying cranium also observed five patients. age range time surgery (excluding 20-year-old male patient who underwent main hospital) 2.6 13 years, mean 6.68 years. female ratio 10:4, duration symptoms 0.2 6 years.(ABSTRACT TRUNCATED AT 250 WORDS)
