Characteristic Findings of Honeycomb-Like Structures in Patients With Chronic Coronary Syndrome Complicated With Myeloproliferative Neoplasms

A 76-year-old woman with a history of essential thrombocythemia and a 64-year-old man with a history of polycythemia vera were both found to have coronary artery stenosis on coronary computed tomographic angiography. Intravascular imaging revealed a honeycomb-like structure with no lipid component, suggesting an organizing thrombus associated with myeloproliferative neoplasms.
