There is a wide variety of common and uncommon nonneoplastic conditions at abdominal radiology that can have imaging features concerning for malignancy. The radiologist should be aware of certain clinical clues, categories of disease, and imaging patterns that suggest a nonmalignant diagnosis, which will help avoid unnecessary anxiety and invasive procedures. There are four broad categories of disease to consider in the differential diagnosis: benign fibrosing disease, inflammatory or deposition disease, infection, and benign mass lesions, which are reviewed in the online presentation.
