Autoimmune diseases involving the gastrointestinal tract: clinical patterns, imaging spectrum, and complications

The authors aim to elucidate the clinical patterns, imaging characteristics, and complications associated with autoimmune diseases that affect the gastrointestinal tract. They categorize these diseases into three groups based on their primary or secondary involvement of the GI system and emphasize the importance of integrating imaging findings with clinical and serologic data to improve diagnosis and management. This review highlights how advances in imaging can enhance understanding and recognition of these complex conditions.
