    Abstract:
    We report herein a case of a 68-year-old Japanese woman in whom calcification of the portal vein was recognized by plain abdominal X-ray radiograph and computed tomography (CT) scan when she presented with repeated thrombosis of the portal system. Following emergency small bowel resection for intestinal necrosis caused by superior mesenteric vein thrombosis, hematological studies revealed the association of dysplasminogenemia. A review of 21 cases of portal vein calcification reported between 1940 and 1990 revealed the average age to be 53.7 +/- 10.2 years and the male/female ratio 17:4. Although the majority of cases suffered from portal hypertension (81%), only 38% had any evidence of liver cirrhosis, while 52% had normal liver function, being comparable to idiopathic portal hypertension. The calcified lesions were located in the portal vein in 100% of cases, the splenic vein in 62%, the superior mesenteric vein in 33%, and the inferior mesenteric vein in 0%. The precise etiology of the calcification was not elucidated in any of the reviewed cases. The patient reported herein is the first reported case of portal vein calcification due to repeated thrombosis of the portal system caused by dysplasminogenemia, which could be accounted as a cause of idiopathic portal hypertension.
