The complete course of the tubular structure could not be identified (Fig. 1, Fig. 3) and the appendix was not initially visualized on the CT.
These (a) axial and (b) sagittal CT images with intravenous contrast demonstrate mesenteric stranding and edema with a thick walled blind ending tubular structure with wall enhancement (black arrow). The wall is discontiguous with adjacent extraluminal air (white arrow), consistent with Meckel's diverticulitis with perforation.

Additionally, the wall is discontiguous and punctate foci of air, which appear to be external to this structure, indicating perforation (Fig. 2a,b).
(a) These axial and (b) coronal CT images with intravenous contrast demonstrate air within the normal appendix (black arrow).

However, a rare Meckel's diverticulitis could have a similar appearance." Retrospective evaluation of the CT scan demonstrates the appendix is present in the right lower quadrant (Fig. 4a, b).
