A case of surgically resected solitary parenchymal brain tumor in a 13-year-old girl,
who was treated 18 months ago with chemotherapy and radiotherapy for cervical vertebral
Ewing sarcoma is presented. The intracranial primitive neuroectodermal tumor was detected
after admission for severe headache. No other metastasis or recurrences were encountered
following 14 months after brain surgery. The authors discuss whether this parenchymal
brain tumor was a metastasis or a second primary Ewing sarcoma/primitive neuroectodermal
tumor.
