Only a few reports have described radiological findings of parasite depicted by postmortem computed tomography (PMCT). We herein present a case in which the PMCT of a 29-year-old man revealed Taenia saginata, a species of tapeworms, inside the intestine. The image of the parasite appeared as a low-density linear or cystic pattern of gas bubbles located within the lumen of the small bowel. We named this finding as 'PseudoPneumatosis intestinalis' sign, since which mimicked the findings of Pneumatosis intestinalis in a clinical setting. In this report, we present the image and discuss the importance of the findings of parasites on PMCT performed before autopsy.
