This is consistent with the increased horizontal momentum in the main duct affecting the branch duct and, thus, the diffuser inlet conditions.
Natural history of branch duct intraductal papillary-mucinous neoplasms of the pancreas without mural nodules: long-term follow-up results.
8 For IPMTs that originate in a branch duct, resection is recommended if the main duct is dilated.
The main duct flow that did not take the branch duct eventually exits into the ceiling plenum through a VAV unit.
44,52,53) Some authors believe the branch duct type is a biologically distinct entity, and therefore every attempt should be made during macroscopic examination to determine the distribution of the lesion, as discussed below (42,44,48,53-55) The adjacent pancreatic parenchyma is usually firm and pale white because of scarring and atrophies from chronic obstruction in main duct-type IPMNs, whereas it is generally normal in branch duct-type IPMNs.
There are 3 types of IPMT: A main duct form that causes diffuse or segmental dilatation of the main pancreatic duct; a branch duct form that causes cystic dilatation of the branch ducts; and a mixed form with elements of both types.

On the other hand, side branch IPMNs (also known as branch duct IPMNs) are less likely to be malignant and are often followed up on serial imaging.
Major and minor dimensions of the main duct are denoted as A and a, respectively, while the corresponding dimensions of the branch duct are denoted as C and c.
On the basis of the location, IPMNs are classified into three types: the branch duct type (small tumours, commonly adenomas, relatively low incidence of carcinoma); the main duct type (more proliferative, larger, complex tumours with atypia); and the mixed type, which includes features of both the above types (4).
Intraductal papillary mucinous neoplasm is an intraductal proliferation of mucinous epithelium that involves the main pancreatic duct (main duct type), the branch ducts (branch duct type), or both (combined type)4 and may lead to cystic dilatation of the pancreatic duct system.
