In another patient, CT, MRCP, and EUS showed a large solid tumor within the cystic lesion and stones within the dilated duct in the pancreas head/uncinated process, mimicking branch duct
type of IPMN with chronic pancreatitis (Fig.

(1,5) ERCP could be very helpful in differentiation of MCNs which usually do not communicate with pancreatic ducts versus psuedocysts or branch duct
IPMNs which communicate with pancreatic ducts.

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.
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).
The VAV unit can be moved to accommodate the various diffuser branch duct
lengths required in the experiment.
As a initially section of ventilation branch duct
, towards the main ventilation duct, the transitional section from the main duct to the ventilation branching duct, as one of the essential sections against the local resistance of ventilation equipment, can be taken.
Many times the problem is that the vent isn't insulated between the ceiling and the branch duct
that it's attached to.
"If they are confined to the branch duct
and are at least, in our estimation, less than 2 1/2 centimeters in diameter and purely cystic on the imaging procedure, we offer the patient follow-up," he explained.
