Reported cases of calcification in the portal vein or its tributaries are few. Magovern and Muehsam1 in reporting a patient with extensive calcification in the portal and splenic veins noted that only 21 cases had been recorded in the past 50 years. The first case to be diagnosed roentgenographically and proved at surgery occurred in 1948.2 In the patient described by Magovern and Muehsam, diagnosis was made roentgenographically and confirmed later at autopsy. None of the patients have been subjected to portacaval anastomoses.
Because of the few cases available for analysis, it was thought worth while to report two cases encountered at the New York Hospital with calcification in the portal vein or tributaries. Both patients were subjected to surgery and have been followed postoperatively. It is hoped that when suitable numbers of cases are available for study, the possible explanation for this phenomenon may be reached.
