Background: We investigated stroke in patients with either benign or malignant primary intracranial tumours to give insights into how malignant and non-malignant intracranial tumours affect stroke and to provide evidence for stroke guidelines for these patients.
Methods: We conducted a retrospective cohort study of patients with benign or malignant primary intracranial tumours admitted with stroke (2011-2022) to a single centre with regional stroke and neuro-oncology units. Data collected included: stroke aetiology, stroke timing relative to tumour diagnosis, pre-stroke disability, post-stroke disability, stroke recurrence and treatment.
