Noninfectious gas accumulation in an infarcted spleen.
BACKGROUND
Intentional selective occlusion of the arterial blood supply to tumors of abdominal organs is a well established therapeutic procedure. Several reports described gas accumulation at the infarcted sites. These gas collections are usually nonsuppurative; however, the differential diagnosis should include abscess formation.


METHODS
We present a 59-year-old patient in whom the splenic artery was accidentally ligated during gastrectomy surgery, with resultant splenic infarction. Gas accumulation was diagnosed by sonography and CT studies. To the best of our knowledge this is the first report ever published in the English medical literature describing nonsuppurative gas formation within an abdominal organ, caused by accidental ligation of its main arterial supply during surgery.


CONCLUSIONS
Possible theories regarding this noninfectious gas accumulation are discussed and the differential diagnosis between abscess formation and noninfectious gas accumulation is emphasized. Establishing the correct diagnosis is of big clinical importance as the treatment of choice is completely different in each one of these entities although the imaging features, in ultrasound as well as in CT, are somewhat similar.
