We describe the case of a 60-year-old man who presented at our hospital with abdominal pain and elevated hepatobiliary enzymes. Computed tomography showed portal thrombosis and cavernous transformation as well as increased wall thickness and a stricture in the biliary tract. At that time, the cause of the portal thrombosis was unknown. During follow-up, the blood cell counts (WBCs and platelets) were remarkably increased, and a test performed for the JAK2V617F mutation was positive. We diagnosed the patient with polycythemia vera. Our findings demonstrate that a patient presenting with portal thrombosis, portal biliopathy, and underlying myeloproliferative neoplasms should be carefully examined, even in the absence of the typical blood alterations.
