Chorea is a rare complication of polycythemia. We report the case of a 70 year-old woman whose polycythemia vera (PV), with Janus Kinase-2 (JAK2) mutation, presented as chorea. Chorea resolved quickly after hydroxyurea therapy.

Hematologic Follow‐up as Clue to Polycythemia Vera due to JAK2 Mutation Presenting as Late Onset Chorea

TLDR
The case of a 73-year old patient with a three-year history of acute-onset left-sided hemichorea following infarction of the right parietal cortex associated with Janus Kinase-2 (JAK2) V617F mutation linked to polycythemia vera (PV) is reported.

Irreversible chorea as the initial presentation of polycythemia rubra vera in an elderly woman

TLDR
A patient whose first clinical manifestation of the PRV was chorea though chorea as the first presentation of thePRV is rare (less than 5%).

Chorea, Pruritus and Polycythemia: Looking for Clues

TLDR
The case of a 75-year-old woman with involuntary movements of the mouth and face with subsequent involvement of the trunk and limbs who was admitted for investigation of the chorea is reported, illustrating the importance of considering PV in the differential diagnosis, since its treatment leads to chorea resolution, thus avoiding serious complications.

Different Magnetic Resonance Imaging Manifestations of Diabetic Chorea in a Case with Hyperglycemia and Another One with Hypoglycemia

TLDR
An 87-year-old woman with chronic kidney disease and was administered with sulphonylurea and dipeptidylpeptodase-4 inhibitor shows right side hemiballismus and head magnetic resonance imaging T1-weighted images revealed a high intensity area in the putamen and caudate nucleus.

Chorea and polycythaemia

TLDR
Two patients with chorea and polycythaemia vera are described and this rare association is reviewed and its pathophysiology discussed.

Chorea disclosing deterioration of polycythaemia vera

TLDR
A case of chorea in a patient previously diagnosed with polycythaemia vera is reported, considered that this was caused by inappropriate treatment with iron because the chorea was markedly reduced after the two first venesections and normalisation of the packed cell volume and haemoglobin parameters.

Hemichorea associated with polycythaemia vera

TLDR
A 66-year-old woman with acute onset hemichorea-ballism with no vascular pathology in the basal ganglia region is presented and a clear relationship was observed between the onset of chorea and worsening of haematological parameters in the patient.

Hemichorea in a patient with JAK2V617F blood cells.

TLDR
Chorea has been reported in patients with polycythemia vera (PV).

Neurologic complications of polycythemia.

TLDR
The neurologic signs and symptoms observed in 511 patients with polycythemia are reported and certain topics of concern are reviewed.

Reversible abnormal functional neuroimaging presentations in polycythemia vera with chorea

TLDR
It is hypothesized that the development of polycythemia chorea is associated with a reversible alteration in the corticobasal ganglia metabolism and disturbed dopaminergic function.

Chorea and polycythaemia.

TLDR
The cause of the choreatic syndrome in polycythaemia is presumably to be explained as a neostriatal hyperviscosity syndrome producing venous stasis, reduced brain blood flow and impaired tissular O2/glucose metabolism.

A case of late-onset chorea

TLDR
HRT-related chorea, possibly caused by a predisposition secondary to rheumatoid arthritis and small-vessel ischemic disease, or subclinical childhood rheumatic fever, is diagnosed.
