Objective: To describe the CT findings of intrasplenic venous thrombos
is in three cases. Materials and Methods: Three adult patients had abd
ominal CT indicative of short-segment thrombosis of an intrasplenic bl
ood vessel. Two patients underwent splenectomy; thrombosis of a segmen
tal splenic vein was confirmed histologically in both cases. Results:
Segmental splenic vein thrombosis appeared on CT as a short, 1-2 cm, l
inear lucency surrounded by normal splenic parenchyma. The probable et
iology of intrasplenic venous thrombosis was main splenic vein occlusi
on related to pancreatitis in two cases and splenic compression and in
flammation by perisplenic abscess in the third case. Conclusion: Throm
bosis of segmental intrasplenic veins is detectable with CT and can be
a secondary CT finding of main splenic vein thrombosis.
