Abstract
Splenic infarction was recognized in 5 of 37 patients who had hepatic neoplasms and who were being examined after transcatheter hepatic arterial embolization by CT [computed tomography] during a follow-up study. CT images of the spleen showed multiple low density areas of a wedge or fused-wedge shape in most patients and of a rod or round shape in others. These low density areas decreased in size in time and in 2 patients they disappeared in 3 mo. Three of the 5 patients complained of a dull pain in the left upper quadrant that did not require any treatment. CT is effective in the diagnosis and assessment of splenic infarction. Awareness of this complication will help to avoid it when hepatic arterial embolization is being performed.
