Fusobacterium necrophorum peritonitis and bacteremia mimicking intestinal necrosis, with hepatoportal venous gas and pneumatosis intestinalis.. A: Contrast-enhanced computed tomography images in the coronal plane revealing small intestinal wall thickening (circle), hepatoportal venous gas (orange arrow), pneumatosis intestinalis (yellow arrow), and ascites (white arrow).. B: Contrast-enhanced computed tomography images in the sagittal plane revealing free air (red arrow) and ascites (white arrow).. C: Laparotomy revealing no necrosis or perforation in the entire colon, small intestine, and gastroduodenum. A blood clot easily peeling off the intestinal wall was observed.. D: Gram staining of the opaque ascites showing a large number of neutrophils, gram-negative cocci, and short rods.

C-reactive protein level of 33.98 mg/dL. Contrast-enhanced computed tomography (CT) revealed HPVG, PI, mesenteric emphysema, free air, ascites, and small intestinal wall thickening (Fig. 1A, B). Although opaque ascites was found, there was no perforation or necrosis of the gastrointestinal tract (Fig. 1C). Gram staining of the opaque ascites showed a large number of neutrophils, gram-negative cocci, and short rods (Fig. 1D).
