(a) Non-enhanced CT scan (coronal plane) showing pneumoperitoneum (extradigestive gas) with locoregional fat stranding (yellow arrow) foreign body responsible for the digestive perforation (blue arrow). (b) Non-enhanced CT scan (sagittal plane) showing the foreign body responsible for perforation. We recognize the drug blister with its lidding seal of aluminum foil (blue arrow). (c) Non-enhanced CT scan (axial plane) showing the empty blister with its lidding seal of aluminum foil and figure. (d) Drug blister.

Peridigestive fat stranding was also observed (Figure 1(a)-(c)).
(a) Macroscopic view. We received a partial ileal resection. Macroscopically, we identified a perforation of ileum wall due to a foreign body, a blister. (b) Microscopic view (x0.6). Microscopically, ileum wall was one side ulcerated and the other perforated (arrows). It shows where the blister touched ileum wall. (c) Microscopic view (x2.6). Ileum wall shows necrosis and perforation (arrow).
