Toxic gastrointestinal side effects of numerous prescribed medications are frequently discussed in clinical and pathology literature. Radiologic manifestations of drug-induced injury have also been described but are less frequently addressed, which may be due in part to a lack of knowledge of the patient’s medications and in part to the often subtle or nonspecific imaging findings. It is therefore important for radiologists in training and practicing radiologists to be familiar with complications in the gastrointestinal tract related to common medical therapies and how they may present on various imaging modalities. Incidence and mechanism of several common medication-induced injuries, as well as their imaging findings and disease processes that can have a similar imaging appearance, will be reviewed in the esophagus, stomach, small bowel, colon, liver and pancreas.

Cases will include, but are not limited to: Pill induced esophagitis NSAID related gastric ulcers and intestinal webs Bowel wall hematoma related to anticoagulation Chemotherapy related bowel pneumatosis and perforation Antibiotic related colitis Hepatic steatosis related to chemotherapy Sinusoidal obstructive syndrome related to antimetabolites Hepatic adenomas related to oral contraceptive pills Pancreatitis related to chemotherapy
