RESUMO
BACKGROUND: Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) present intricate challenges due to their diverse clinical manifestations and thrombotic complications. Thromboembolism (TE) incidence in newly diagnosed AML patients is noteworthy, with arterial TE linked to poorer overall survival. Ischemic strokes, although relatively low in prevalence, carry significant clinical implications. CASE DESCRIPTION: We report the case of an 84-year-old male with Type 2 Diabetes, Hypertension, and Chronic Kidney Disease, presenting with seizures, focal neurological deficits, and pancytopenia. An unexpected diagnosis of AML or MDS emerged during the investigation. Despite interventions, the patient's condition deteriorated, leading to a fatal outcome weeks later. CONCLUSION: This case underscores the intricate relationship between hematologic malignancies and ischemic stroke. The rarity of this complication emphasizes the importance of understanding the multifaceted mechanisms at play, including hyperleukocytosis, pro-inflammatory cytokine release, coagulation cascade activation, and direct interactions with endothelial cells. In our literature review, analysis of 15 cases, including ours, revealed a wide age range (3-87 years) and a gender bias towards females. AML diagnosis was predominant, with uniformly low platelet counts. Cortical infarctions, especially in the anterior circulation, were common. Hyperleukocytosis, disseminated intravascular coagulation (DIC), and fatal outcomes were observed in a subset of cases. Despite the grim statistics and often poor prognosis, the identification of specific risk factors, such as thrombocytopenia and cytogenetic abnormalities, offers avenues for targeted prevention and management.
