Abstract

Recently, three-dimensional computed tomography (3D-CT) and reconstruction by Synapse Vincent has been applied. The case was 73-year-old male with lower abdominal pain and fever. The images of 3D-CT with reconstruction suggested the presence of a sigmoid diverticulum penetrating the mesenterium and an abscess (60x50x40mm in large) in the sigmoid colon and mesocolon. Treatment consisted of laparoscopic drainage of the abscess and administration of ampicillin/sulbactam (ABPC/SBT). One month later, CT showed the shrink of the abscess. Laboratory tests over a 3-week period showed normalization of CRP (13.4 to 0.4 mg/dL) and white blood cell (WBC) counts (8000 to 5100 /μL).
