A rare case of multicystic disseminated astrocytoma with pilomyxoid characteristics in a 4-year-old child

Abstract

Pilomyxoid astrocytomas are a more aggressive variant of pilocytic astrocytoma. Over the last 14 years, there has been increasing evidence to suggest that these tumours are distinct pathological entities to pilocytic astrocytomas. Radiological features of these tumours are slowly emerging in the neuroradiological literature. We report a unique radiological appearance of a multicystic, disseminated astrocytoma with pilomyxoid characteristics presenting in a 4-year-old boy and highlight the importance of considering this diagnosis with similar imaging.
