MRI findings of pancreatic intraductal oncocytic papillary neoplasm: three case reports and review of literature.

ABSTRACT:

Background

Pancreatic intraductal oncocytic papillary neoplasms (IOPNs) are uncommon precancerous lesions frequently mistaken for other tumors because of their similar imaging characteristics. The concept of IOPN was first proposed by Adsay et al. in 1996. Recently, an increasing number of reviews on IOPN have been published, however, literature focusing on its imaging features remains scarce. This study retrospectively analyzed the clinical, imaging, and pathological data of three patients with pathologically confirmed pancreatic IOPN, alongside a review of the latest findings in relevant literature.

Case presentation

We described three cases of IOPN in elderly patients, with a male-to-female ratio of 1:2. Among these cases, only one patient exhibited abdominal pain, while
