Pemigatinib is a fibroblast growth factor receptor inhibitor (FGFRi) approved for the treatment of patients with previously treated biliary tract cancer with FGFR2 fusion.

We herein report the case of a 54-year-old woman with unresectable cholangiocarcinoma-initiated pemigatinib after failure of gemcitabine plus S-1 (GS).

A 71-year-old man presented to our hospital because of abdominal bloating. Diagnoses of early-stage pancreatic body cancer with pancreatic duct rupture, pancreatic ascites, and formation of a pseudocyst were made on the basis of blood tests, multidetector dynamic computed tomography, endoscopic ultrasonography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography.

Methods: This study retrospectively analyzed 40 patients with localized AIP and 71 patients with PDAC who underwent abdominal MRI with DWI (b = 0 and 1000 s/mm). Their ADC values at the lesion sites and five MRI findings useful for diagnosing AIP were evaluated.
