Apoplexy of a collision tumour composed of subependymoma and cavernous-like malformation in the lateral ventricle: a case report

Abstract

Subependymomas are rare benign tumours arising from subependymal glial precursors that usually remain asymptomatic or may present due to obstruction of cerebrospinal fluid pathways. We describe the first report of intraventricular haemorrhage from subependymoma and cavernous-like malformation collision tumour in a 74-year-old male presented with an impaired level of consciousness.
