In centers of pancreas surgery, they account nowadays for approximately 25% of cases of resected pancreatic neoplasms . IPMN is an intraductal tumor whose papillary epithelial proliferation and mucin production leads to cystic dilatation of the involved ducts. IPMNs are therefore included among the cystic tumors of the pancreas .

They are most commonly seen in elderly patients. On imaging, particularly MRCP, they are characterized by single or multiple unilocular or septated pancreatic cystic lesions communicating with the pancreatic ducts. Background Several changes have been made to the revised 2017 international consensus guidelines for management of pancreatic intraductal papillary mucinous neoplasms (IPMNs). However, the diagnostic performance is yet to be verified.

Dr Mohamed Saber and Assoc Prof Frank Gaillard et al. Intraductal papillary mucinous neoplasms or tumors (IPMNs or IMPTs) are epithelial pancreatic cystic tumors of mucin-producing cells that arise from the pancreatic ducts. They are most commonly seen in elderly patients. On imaging, particularly MRCP, they are characterized by single or multiple unilocular or septated pancreatic cystic lesions communicating with the pancreatic ducts.

It can occur in both men and women older than 50. Depending on its location and other factors, IPMN may require surgical removal. Intraductal papillary mucinous neoplasms are tumors that grow within the pancreatic ducts (the pancreatic ducts are the "tubes" within the pancreas that are used to transport fluids to the bowel to help with digestion). Intraductal papillary mucinous neoplasms are also characterized by the production of thick fluid, or "mucin", by the tumor cells.

Relative indications for surgery in IPMN include a main pancreatic duct (MPD) Alireza] Umea Univ, Umea Ctr Funct Brain Imaging UFBI, Umea, Sweden.

As such IPMN is viewed as a precancerous condition. 2020-08-17 MRI of the pancreas with MRCP has emerged as a reliable tool for detecting and characterizing cystic pancreatic lesions. The superior soft-tissue and contrast resolution makes MRI a sensitive study for assessing the morphologic features of cystic lesions, including their communication with the main pancreatic duct [ 3 , 16 , 30 , 36 , 37 ].

We believe that the better performance of the MRI set for the diagnosis of IPMN was attributed to the greater predictability of the MRCP set regarding the ductal communication of the lesion with the main pancreatic duct compared to MDCT (P < 0.05). One of the most common incidentally detected pancreatic lesions is the intraductal papillary mucinous neoplasm (IPMN), which are dilated side branches of the pancreatic duct due to ductal cells producing too much mucin/fluid (hence the name and need for MRCP sequences to evaluate for communication with the main pancreatic duct).

MRI based on its superior contrast resolution for recognition of septum, nodules, and duct communication, can be a procedure of choice for evaluation of a pancreatic cyst, as has been suggested by a consensus of radiologists.

Accepted for publication Nov 19, 2015. pancreatic cysts are asymptomatic and the nonspecific nature of symptoms requires clinical discernment (Conditional recommendation, very low quality of evidence) 2. Magnetic resonance imaging (MRI) or magnetic resonance cholangiopancreatography (MRCP) are the tests of choice because of their non- invasiveness, lack of radiation, and Routine pancreatic juice sampling for cytological assessment under endoscopic retrograde pancreatography (ERP) for indolent BD-IPMN is not recommended in Fukuoka guidelines 2012, because ERP has a risk of lethal pancreatitis and sensitivity of pancreatic juice cytology to detect malignant IPMN is not so high, ranging from 10 % to50 % (3, 27, 32, 34).

Materials and Methods In this retrospective study, two radiologists analyzed the preoperative contrast-enhanced CT and MRI of patients with surgically resected pancreatic IPMNs from January 2007 to December 2017. The diagnostic performance of CT and MRI were analyzed by using receiver operating curve analysis.

Transabdominal ultrasound is usually limited for diagnosing IPMN. An intraductal papillary mucinous neoplasm (IPMN) is a growth in the main pancreatic duct or one of its side branches. IPMN may be precancerous or cancerous. It can occur in both men and women older than 50.

A combination of T2-HASTE and DWI has been shown to have similar accuracy to a comprehensive contrast-enhanced MRI protocol for the detection of pancreatic cancer.43 A recent study suggested that MRI with MRCP has a better diagnostic performance than endoscopic ultrasound (EUS) for differentiating malignant from benign pancreatic IPMN and MCN,44 but conclusive evidence is lacking.

It can occur in both men and women older than 50. Depending on its location and other factors, IPMN may require surgical removal.

Although it is unclear what proportion of these incidentally-discovered pancreatic cysts represents IPMN, surgical series have shown that most of the larger ones indeed are branch duct IPMN (BD-IPMN). 2018-05-01 Pancreatic divisum is one of the common congenital causes for CP for which the modality of choice is MRI. However, in advanced stages CT can recognise the changes due to pancreatic divisum. The inflammatory, fibrotic changes and the ductal changes are limited to the dorsal part of pancreas whereas the ventral pancreas appears normal (39).
