Typical clinical characteristics, neuroradiologic findings, and initial neuroradiologic studies were reviewed for 40 patients 1-weighted MRI scans, 10 (67%) demonstrated low-signal intensity tumors, and 15 (94%) of the 16 T2-weighted scans revealed high-signal tumors. Forty- three percent of the tumors were cystic. Blood was observed within only 2 tumors and peritumoral edema was uncommon. Twenty-five percent of the ependymomas extended out to involve the dura, and 97% of the infratentorial tumors showed characteristic plasticity. Hydrocephalus was present in 34 (85%) children.
