Splenic Infarct as the Presenting Manifestation of Essential Thrombocythemia.

Essential thrombocythemia is a chronic myeloproliferative neoplasm characterized by thrombotic and hemorrhagic complications. Essential thrombocythemia can be considered a risk factor for thrombotic events. A 34-year-old female presented with sudden onset of abdominal pain from splenic infarction for which she underwent splenectomy. Bone marrow examination performed because of increasing thrombocytosis led to a diagnosis of essential thrombocythemia. Postoperatively, she was maintained on low-dose aspirin and doing well at follow-up. Our patient had an undiagnosed case of essential thrombocythemia and presented with symptoms related to splenic infarction. To the best of our knowledge, few cases of splenic infarction consequent to essential thrombocythemia have been reported.
