FIG1
Abdominal ultrasound was negative for any acute abdominal process; abdominal radiography showed air-filled bowel distention without pneumatosis (Figure 1), and Meckel's scan revealed no evidence of ectopic gastric mucosa.
Colonoscopy view of the rectosigmoid junction. The figure demonstrates the colonoscopy view of the rectosigmoid junction with exudated, friable, erythematous mucosa (enclosed within circles pointed by arrows) and superficial erosions with a decreased vascular pattern

FIG2
The colonoscopy with biopsy revealed an exudated, friable, erythematous mucosa at the rectosigmoid junction with superficial erosions and decreased vascular pattern (Figure 2) and erythematous and edematous mucosa at the transverse and descending colon (Figures 3, 4).
Colonoscopy view of the descending colon. The figure demonstrates the colonoscopy view of the descending colon with erythematous and edematous mucosa (enclosed within circles and evident in the right-upper and bottom-left images)

FIG5
The EGD revealed linear erythematous mucosa in the gastric body and the first portion of the duodenum with swollen mucosa (Figures 5, 6).
Endoscopic view of the first duodenal segment. The figure demonstrates the endoscopic view of the first duodenal segment showing swollen mucosa (arrows in the top-left and bottom-right images, circles in the top-right and bottom-left images)

FIG6
The EGD revealed linear erythematous mucosa in the gastric body and the first portion of the duodenum with swollen mucosa (Figures 5, 6).
Histopathology sample of the sigmoid colon. The figure shows the histopathologic sample of the sigmoid colon with evident mild acute colitis and acute neutrophilic crypt abscesses (indicated by arrows)

FIG7
The microscopic findings of both studies revealed mild acute-on-chronic gastritis with crypt abscesses, mild acute-on-chronic duodenitis with mild villous blunting, mild acute-on-chronic colitis in the transverse and descending colon, and mild acute colitis with acute neutrophilic crypt abscesses in the sigmoid and rectum (Figure 7).
