Rapid Recurrence of Pediatric Cerebellar Pilocytic Astrocytoma with High Ki-67 Index and KIAA1549-BRAF Fusion: A Case Report

2026-07-07

Abstract excerpt

<title>Abstract</title> <p>Pilocytic astrocytomas (PA) are typically slow-growing, WHO Grade 1 tumors with favorable long-term prognoses following surgical resection. However, rare cases exhibit aggressive clinical behavior. This case study describes an exceptionally rapid recurrence of a pediatric cerebellar PA in a 3-year-old female and discusses the implications of high Ki-67 proliferation indices and molecula...
