Cavernoma of the portal vein is defined as a formation of venous channels within or around a previously thrombosed portal vein. We experienced a 50-year-old @entity1 who presented a huge @entity99 with right upper quadrant dull @entity158 . Abdominal computed tomography showed a huge sponge-like @entity99 with cavernous transformation of portal vein along the common bile duct and common hepatic duct. She had increased hemoglobin/hematocrit (15.7 g/dL/49.1%) and red blood cell mass (35 mL/kg). Platelet count was 450,000/microL and white blood cell count was 13,500/microL. @entity1307 level was low normal range (10.2 mU/mL). Bone marrow biopsy showed a moderately @entity236 and overall cellularity was about 80-90%. Megakaryocytes were slightly increased in number with abnormal clusterings Myelopoiesis and erythropoiesis were also slightly increased with moderate to severe @entity82 . She was diagnosed as @entity6582 vera with cavernous transformation of portal vein. Repeated @entity715 occurred in the leg and the toe and was treated with angioplasty and thrombolytic therapy with phlebotomy.
