Abstract: Background Primary Immune Thrombocytopenia (ITP) is typically associated with bleeding risks due to thrombocytopenia. However, paradoxical thrombotic events such as stroke may occur in rare cases, posing a clinical dilemma in management. Case presentation We present the case of a 65-year-old male with a history of ITP and recurrent venous thromboembolism who experienced multiple ischemic strokes despite therapeutic anticoagulation. The initial presentation revealed subacute bilateral frontal infarcts while on Rivaroxaban, with extensive workup suggesting a cryptogenic stroke etiology. The patient was subsequently switched to Warfarin and treated for ITP with steroids and Rituximab, resulting in improved platelet counts. Eight months later, he suffered a pontine infarct despite therapeutic INR. His anticoagulation goal was adjusted, and he remained stroke-free on close follow-up. Discussion: This case highlights the underrecognized thrombotic risk in ITP patients and the challenges in balancing anticoagulation with bleeding risk. Mechanisms may include increased platelet microparticles and immune-mediated endothelial injury. The individualized INR target and ITP treatment strategy led to improved clinical outcomes. Conclusion ITP can predispose patients to thrombotic complications such as stroke, even in the setting of thrombocytopenia. Personalized anticoagulation goals and multidisciplinary care are critical for optimal management. Further studies are needed to establish standardized treatment guidelines for this unique patient population.
