Case Discussion

Very challenging clinical and radiological case with changing imaging features over a short period of time. It is remarkable and unusual to see a shifting pattern of colitis and enteritis over a 2-week timeframe, prompting consideration for uncommon diagnoses. 

This patient underwent extensive workup and was found to have EDG/colonoscopy biopsies with focally increased eosinophils, eosinophilia on bone marrow biopsy, and elevated eosinophils in the ascites. The patient rapidly improved after starting steroids, helping to confirm the diagnosis. 

The differential diagnosis for such a pattern of small bowel inflammation as seen on the last series also includes vasculitis (such as lupus), Crohn disease, and ACE-inhibitor-related angioedema.
