Polycythemia vera, a rare and poorly documented disease in cats, was diagnosed in a 4-year-old domestic shorthair cat admitted because of seizures. The diagnosis was made on the basis of high PCV, normal serum erythropoietin concentration (as determined by bioassay, using rabbit bone marrow cells),
A 1-year-old neutered male Labrador retriever mixed breed dog was referred for peracute onset of ataxia and seizures. Hematocrit at presentation was 84%. Magnetic resonance imaging of the brain revealed a lesion in the right caudate nucleus consistent with infarction. Postmortem findings were
Migraine-like cerebral transient ischemic attacks (MIAs) and ocular ischemic manifestations were the main presenting features in 10 JAK2(V617F)-positive patients studied, with essential thrombocythemia (ET) in 6 and polycythemia vera (PV) in 4. Symptoms varied and included cerebral ischemic attacks,
BACKGROUND
Cerebral arteriovenous malformations (AVM) usually present with headache, hemorrhage, or seizure. Erythropoietin (EPO) has demonstrated protective effects against ischemia within the CNS.
METHODS
The authors report a patient with a cerebral AVM and concurrent polycythemia associated with
Essential thrombocythemia is a clonal myeloproliferative disorder, characterized predominantly by a markedly elevated platelet count without known cause. We report a case that was recognized during investigation of a transient ischemic attack, and review the neurologic findings in 33 patients with
Two patients with cyanotic congenital heart disease (CHD) and erythremia were seen for abrupt onset of focal neurologic deficits and/or seizure without signs of infection or increased intracranial pressure. Clinical features and initial computed tomography (CT) in both cases suggested stroke.
