In particular, AIP can present at CT scan, MRI or endoscopic ultrasound (EUS) as a focal mass, sometimes with no other specific peculiarities. Furthermore, current international guidelines1 2 consider EUS only as a way to obtain cyto-histological specimens to exclude malignancy, regardless to its diagnostic capacity based on morphologic aspects.For these reasons, we read with great interest the paper by Marya et al 3 about the possible role of a new EUS-convolutional neural network (EUS-CNN) model for the diagnosis of AIP. In this model, videos and pictures of EUS, accurately preselected by the endosonographers, were … ER -
