Department of Hematology, Kyoto City Hospital.

A 64-year-old man presented to the emergency department with sudden-onset upper abdominal pain and pain in the left chest area. His platelet count was 121.7×10/µl. Computed tomography (CT) showed bilateral adrenal swelling and inflammation of the adjacent tissue. Diffusion-weighted magnetic resonance imaging (MRI) showed hyperintensity in the bilateral adrenal glands. The patient was diagnosed with bilateral adrenal infarction. A bone marrow biopsy yielded a diagnosis of essential thrombocythemia, and a positive JAK2 V617F mutation was detected. He presented with recurrent adrenal infarction and developed aortic mural thrombosis and splenic infarction. We administered aspirin and performed cytoreductive therapy with hydroxyurea and anagrelide; however, the patient then went into heart failure resulting from coronary artery stenosis. We then added prasugrel to the list of medicines administered to manage his condition. Bilateral adrenal infarction is a very rare thrombotic event of essential thrombocythemia. CT and MRI were useful for making the diagnosis; however, we also had to rule out acute coronary syndrome or intestinal ischemia. Our patient presented with strong thrombotic diathesis, which prompted us to use dual antiplatelet therapy; however, further studies are needed to confirm the efficacy and safety of this treatment.
