Fourteen @entity1 had mesenteric, portal, or @entity49 that was diagnosed primarily by contrast-enhanced CT. The group included five @entity1 with @entity1003 , three with @entity3123 , two with @entity82 and @entity101 , one with @entity788 , and one with @entity157 . In two @entity1 , no etiology was determined. In all cases, CT easily identified low-density @entity49 , which frequently involved more than one vein. In four @entity1 , all three splanchnic veins were involved; five @entity1 had occlusion of two veins. In five @entity1 , only one vein was involved. Additional CT findings included ascites, collateral veins, @entity382 , and @entity381 . No venous wall enhancement was found. CT also was helpful in defining the cause of @entity715 in six of 14 @entity1 . Mesenteric @entity4 and/or bowel wall thickening was not identified. None of the @entity1 had classic clinical evidence of @entity432 , and none died primarily of that disease. The major morbidity suffered by these @entity1 stemmed from complications of @entity432 , and nine @entity1 ultimately required sclerotherapy, splenectomy, and portal decompression. We conclude that CT is useful in the diagnosis of @entity49 . Our experience suggests that mesenteric, @entity49 may occur more commonly than has been previously thought and that the disease in many cases is not life threatening.
