title: Metastatic Diffuse Intrinsic Pontine Glioma to the Peritoneal Cavity Via Ventriculoperitoneal Shunt: Case Report and Literature Review.
abstract: Extraneural metastatic disease resulting from a primary central nervous system neoplasm is a rare clinical finding in the pediatric population. We report a case of peritoneal glioblastoma carcinomatosis following placement of a ventriculoperitoneal shunt and chemoradiotherapy in a 6-year-old female patient who initially presented with diffuse intrinsic pontine glioma. This case demonstrates the importance of evaluation of extraspinal structures when imaging for extension of disease. Additionally, this report highlights the cross-sectional imaging characteristics of glioblastoma peritoneal carcinomatosis and presents additional information that will facilitate the timely diagnosis of extraneural metastases of primary high-grade glial neoplasms in the pediatric population.
