IPMN Hauptgangtyp

Intraductal

papillary mucinous neoplasm of the pancreas (IPMN): clinico-pathological correlations and surgical indications. Colangio-MRI: main duct IPMN involving the whole gland, three-dimensional and axial reconstruction.

Fibrous

dysplasia for radiologists: beyond ground glass bone matrix. Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in McCune-Albright syndrome (blue arrows). T2-weighted MRI (a), T1 contrast-enhanced MRI (b). Coronal maximum intensity projection from a 3D T2-weighted MRCP acquisition shows IPMNs (c). Please note, a fibrous dysplasia lesion in the left rib (green arrows)

Cystic

pancreatic lesions: MR imaging findings and management. Diffuse MD-IPMN. At MRCP (a), a diffuse enlargement of the MPD is appreciable through the gland with a grape-like dilatation of branch ducts (arrow) and without significant causes of obstruction nor calcifications both on T2w (b) and CT (c)

Cystic

pancreatic lesions: MR imaging findings and management. Segmental MD-IPMN. At MRCP (a), a segmental dilatation of the MPD is appreciable in the body of the pancreas. The MPD upstream shows signs of chronic obstructive pancreatitis (finger-like dilatation of branch ducts), but the thickness of the pancreatic gland is normal (b). After 20 months, the dilatation of the MPD upstream is no longer appreciable (c), due to atrophy of the pancreatic gland (d)

Cystic

pancreatic lesions: MR imaging findings and management. Evolution of a mixed MD-IPMN. At T2w (a) and MRCP (b), a dilatation of a branch duct in the tail of the pancreas with a slight enlargement of the MPD in the tail. After 5 years, a diffuse dilatation of the MPD is appreciable
