Intrasplenic venous thrombosis: CT findings.
OBJECTIVE
To describe the CT findings of intrasplenic venous thrombosis in three cases.


METHODS
Three adult patients had abdominal CT indicative of short-segment thrombosis of an intrasplenic blood vessel. Two patients underwent splenectomy; thrombosis of a segmental splenic vein was confirmed histologically in both cases.


RESULTS
Segmental splenic vein thrombosis appeared on CT as a short, 1-2 cm, linear lucency surrounded by normal splenic parenchyma. The probable etiology of intrasplenic venous thrombosis was main splenic vein occlusion related to pancreatitis in two cases and splenic compression and inflammation by perisplenic abscess in the third case.


CONCLUSIONS
Thrombosis of segmental intrasplenic veins is detectable with CT and can be a secondary CT finding of main splenic vein thrombosis.
