Autoimmunpankreatitis

Zusammenfassung

Seit den 1990er-Jahren ist die Autoimmunpankreatitis (AIP) als eigenständige Form der Pankreatitis bekannt, seit Kurzem ist sie als solche auch anerkannt. In diesem Beitrag liegt der Schwerpunkt auf der Diagnostik der Autoimmunpankreatitis und dabei insbesondere auf der Bildgebung, die dabei eine entscheidende Rolle spielt.

Abstract

Autoimmune pancreatitis is an independent form of pancreatitis that has been recognized for a short time. Imaging plays a crucial role in the diagnosis of AIP, but cannot define it alone. There are two types of AIP that cannot be differentiated purely in terms of image morphology. Imaging criteria for the presence of AIP are focal or diffuse enlargement of the pancreas with typical changes in the distribution of contrast medium and changes in the pancreatic duct. The main duct can have solitary or multiple strictures, although these are present without an upstream widening of the duct. The most important diagnostic tool is MRI with contrast medium and/or endosonography.
