We described pancreatic and extrapancreatic CT\/MRI findings and explored retrospective interpretive patterns, including unrecognized diffuse disease. Methods: This retrospective single-center study included 40 selected patients with archived definite\/probable JPS 2018 classifications. CT was available for 31 patients and MRI\/MRCP for 36. Two radiologists reviewed features independently and reached consensus; access to diagnostic information during these assessments could not be reconstructed. Six operated patients formed an illustrative case series reviewed post hoc with final diagnoses known. Results: Diffuse disease occurred in 28\/40 (70.0%), a capsule-like rim in 33\/40 (82.5%), homogeneous portal venous and\/or delayed enhancement in 40\/40, and qualitative diffusion restriction in 36\/36 MRI examinations. Extrapancreatic abnormalities compatible with IgG4-related involvement were recorded in 32\/40 patients (80.0%): biliary abnormalities in 30\/40 and renal abnormalities in 11\/40. Two extrapancreatic presentations initiated evaluation. Three of six operated patients had diffuse disease. The narratives illustrate biliary-dominant findings, temporal change, and discordant multimodality evidence. These are selected-cohort frequencies, not population prevalence or sensitivity estimates. Imaging also contributed to diagnostic adjudication, creating incorporation bias; malignant controls were absent. Conclusions: The findings describe an imaging spectrum and generate educational hypotheses. The diagnostic-role framework has not been validated as a diagnostic algorithm or shown to reduce misdiagnosis or unnecessary surgery. Independent comparative validation is required.<\/jats:p>","DOI":"10.3390\/diagnostics16193129","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T10:00:34Z","timestamp":1790589634000},"page":"3129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Extrapancreatic
