Introduction:
Ischemic stroke secondary to polycythemia is a rare but serious complication, particularly in young adults. Early recognition and intervention can lead to rapid neurological recovery.
Case Presentation:
A 21-year-old male from Western Uganda presented with sudden-onset right-sided hemiparesis and slurred speech. He had no prior history of thromboembolic events but reported chronic headaches and fatigue. Physical examination revealed facial asymmetry, right-sided weakness (power 3/5), and hyperviscosity signs. Laboratory tests confirmed polycythemia (Hb: 22 g/dL, Hct: 68%). Brain CT showed an acute left middle cerebral artery (MCA) infarct.
Management:
Emergency phlebotomy (500 mL) was performed, followed by hydration and low-dose aspirin. The patient showed significant improvement within 48 hours, with near-complete resolution of symptoms at one-week follow-up.
Conclusion:
Polycythemia-induced stroke, though rare, should be considered in young patients with unexplained thromboembolic events. Phlebotomy remains a rapid and effective treatment, especially in resource-limited settings.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
