Polycythemia Vera Presenting with Generalized Chorea: A Case Report and Review of the Literature / 대한내과학회지

ABSTRACT

Polycythemia vera (PV) is a myeloproliferative neoplasm characterized by erythrocytosis. Clinical symptoms can range in severity from headache and tinnitus to thrombohemorrhagic complications. Neurologic symptoms are common at the onset of polycythemia; however, chorea due to PV is a rare complication. We present the case of a 77-year-old female who was referred to our hospital because of choreic movement of the limbs, head and face. She was diagnosed with JAK2V617F mutation-positive PV. Her chorea was completely resolved by phlebotomy combined with hydroxyurea and aspirin.
