title: Necrotic tumor simulating intraabdominal abscess: a case report.
abstract: The appearance of gas was observed within a lymphomatous mass at the time of therapy, simulating an abscess on computed tomography and abdominal radiography. There was no evidence that the tumor was infected. No fistula could be demonstrated between the mass and a hollow viscus, and phlegmonous necrosis of the tumor is suggested as an etiology.
