ABSTRACT
BACKGROUND: Polycythemia is a rare but important preventable cause of stroke with potential for recurrence when not identified and appropriately managed. CASE PRESENTATION: This is a case of a 55-year-old Ghanaian who presented to our tertiary facility after a 2-month delay with a history of sudden onset of right-sided hemiparesis and expressive aphasia. He had suffered a previous stroke with left hemiparesis 2 years previously where hypertension and polycythemia were identified and treatment initiated. However, patient defaulted treatment for 18 months prior to the onset of recurrent stroke. A cranial CT scan revealed chronic right and subacute left middle cerebral artery territorial infarcts. Presenting hematocrit was 71%. Treatments initiated included high dose hydroxyurea, venesections, and dual antiplatelet therapy of Aspirin and Clopidogrel. He has since been discharged and remains stable under follow-up with moderate functional deficits- Modified Rankin score of 3/6 and the hematocrit of 54% at 3 months postdischarge. CONCLUSIONS: Default of therapy for polycythemia is associated with a profound risk of recurrent strokes requiring patient education and support to prevent the devastating consequence of this modifiable but rare cause of stroke. This case report highlights the challenges of instituting secondary prevention for stroke in resource-limited settings.
