Presentation
Fever, abdominal pain and diarrhea for few days. The pain was mainly epigastric, dull and aching in nature. Loose bowel motions about five times per day.
Patient Data
There is mural thickening and thumbprinting at the colonic hepatic flexure associated with fat stranding, mesenteric lymphadenopathy, and a small amount of free fluid, in keeping with colitis.
Case Discussion
Infectious colitis is the inflammation of the colon secondary to bacterial, viral, parasitic, or fungal infection. In this case the provisional causative organism was thought to be Clostridioides difficile but the stool analysis was negative for its toxin on serial samples. The laboratory work-up was positive for methicillin-resistant staphylococcus aureus (MRSA); the probable causative organism.
