Infectious colitis due to Salmonella paratyphi B – Example
This 72-year-old female patient presents with a five-day history of bloody diarrhea associated with nausea and vomiting. After inpatient admission, she required parenteral fluid repletion and blood transfusions. Ultrasound revealed wall thickening along the entire length of the colon.
The terminal ileum was within normal limits on colonoscopic examination. The colon, however, was characterized by fairly uniform changes. The video begins in the transverse colon. The mucosa is erythematous, edematous, in some places covered with bloody deposits, with individual flat ulcerations and pronounced vascular changes with small, pale vessels.
Histology returned unremarkable mucosal findings from the terminal ileum and a mild erosive colitis. Stool culture was positive for Salmonella paratyphi B.
