Radiotherapy induced intracranial growing teratoma syndrome in a pediatric germ cell tumor: a case report and literature review

Abstract

Case Presentation: We report a case of 4-year-old boy with three months history of headache and projectile vomiting which usually occurred at the early hours of the day. Computer tomographic (CT)-scan of the head showed lateral and third ventricles enlargement which signify hydrocephalus while magnetic resonance imaging (MRI) revealed an enhanced cystic mass around the pineal body. The patient was initially treated with radiotherapy and three months later his symptoms worsened. A follow-up MRI revealed aggressive recurrence of the tumor.
