@entity1 @entity455 @entity548 @entity76 @entity1296 @entity2477 @entity10
BACKGROUND: We report a case of progressive multiple @entity2477 . @entity1 AND METHOD: A 16-year-old @entity1 presented with a 2-month history of @entity10 and @entity1296 . Six years earlier, he underwent surgery for @entity76 and subsequent chemoradiotherapy according to the M-051 protocol of the Korean Society of Pediatric Neuro-Oncology. Follow-up brain magnetic resonance imaging (MRI) revealed a tiny @entity548 on the cerebellum 3 months after 23.4-Gy craniospinal and 32.4-Gy boost radiotherapy. RESULT: The multiple @entity548 had progressively developed on the whole brain without any symptoms for 6 years. On admission, MRI revealed a 1.5-cm enlarged mass with subacute @entity548 on the right frontal area. The mass was totally removed and diagnosed as @entity2477 . However, 5 months later, the @entity1 complained of a @entity10 . MRI revealed 1.4- and 0.7-cm enlarged masses on the left frontal and right temporal areas with internal @entity548 , respectively. The left frontal mass was totally removed, and the histopathological finding was suggestive of @entity2477 . CONCLUSION: This case showed early-developed multiple @entity548 after radiotherapy, which had been progressive and were associated with some symptomatic @entity2477 . Pediatric @entity1 with brain radiotherapy should undergo radiological check-up to identify @entity455 , especially symptomatic @entity1 .
