Symptomatic intraventricular xanthogranulomata. A report of 2 cases

Intraventricular xanthogranulomata may occasionally be seen as incidental findings at post-mortem. It is however, exceptionally rare for them to become symptomatic, but if they do, it is usually attributable to obstruction of the CSF pathways. Two further symptomatic cases are presented and the literature is reviewed. Treatment is surgical excision, but stereotactic biopsy should be avoided due to the often impenetrable nature of the capsule.
