Abstract
The efficacy of adjuvant chemotherapy for patients with poor-risk medulloblastoma/primitive neuroectodermal tumors (MB/PNET) has been studied at the Children’s Hospital of Philadelphia, University of Pennsylvania, PA.
Highlights
A repeat ultrasound at 7 mos showed increased echogenicity in the midline with normal ventricles, interpreted as blood in the third ventricle with calcification
CT showed a large midline area of decreased density extending into the lateral ventricles, consistent with a lipoma of the corpus callosum and calcifications
At 18 mos the head is large and development is delayed at the 12 mo level
Summary
A repeat ultrasound at 7 mos showed increased echogenicity in the midline with normal ventricles, interpreted as blood in the third ventricle with calcification. His head circumference was at the 75th percentile and disproportionately large. CT showed a large midline area of decreased density extending into the lateral ventricles, consistent with a lipoma of the corpus callosum and calcifications. At 18 mos the head is large and development is delayed at the 12 mo level.
