摘要
We report a case of a 3-year-old girl with a 9-month history of focal neurologic finding and signs of increased intracranial pressure. Radiological imaging studies showed a minimally heterogeneous enhancing large tumor involving left parietal region and partly filling the left lateral ventricle. Microscopically, the tumor contained prominent small true rosettes set into areas of fibrillar neuropil-like matrix. Foci of cellular tumor with extensive apoptosis were present. The neuropil-like areas and true rosettes were positive for synaptophysin immunostain. The tumor was negative for GFAP and neurofilament protein immunostains. MIB-1 proliferation index was high focally approaching 80%.
