• Cystic lesions of the pancreas occur in 2.5% of the population (increasing prevalence with age) • Many of these lesions will represent pre-cancerous lesions: IPMN and MCN • IPMN represents a whole gland process with several genetic pathways to distinct forms of invasive cancer • Resection should be recommended when there is concern for high-grade dysplasia Main duct IPMN Large branch duct lesions with mural nodules The size of the IPMN and the diameter of the main pancreatic duct associated with incidence of IPMN-derived carcinoma (SHR 1.85; 95% confidence interval 1.38-2.48 for a 10-mm increase in the IPMN An MRCP is a non-invasive test that uses a strong magnetic field to view the liver, pancreas, gallbladder, and bile ducts. This test can show if the bile ducts are obstructed, such as by a suspected IPMN. Contrast dye, given either via a drink or an IV, may be used during this test to help enhance the images. Intraductal papillary mucinous neoplasms (IPMNs) are some tumor structures that are developed in ducts of pancreas composed of mucin-producing columnar cells . IPMNs are responsible for less than 1-2% (about 2.5% in some studies) [ 2 ] of all neoplasms of the pancreas and do not have any particular sign and symptoms [ 3 ] while some of them can present with jaundice and acute pancreatitis. Intraductal papillary mucinous neoplasm (IPMN) is the most frequently detected premalignant lesion that involves the main pancreatic duct (MPD), branch duct, or both.

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). MRI versus CT. CT will depict most pancreatic lesions, but is sometimes unable to depict the cystic component. MR with heavily weighted T2WI and MRCP will better demonstrate the cystic nature and the internal structure of the cyst and has the advantage of demonstrating the relationship of the cyst to the pancreatic duct as is seen in IPMN. MRI of the pancreas with MRCP has emerged as a reliable tool for detecting and characterizing cystic pancreatic lesions.

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 . Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct.IPMN tumors produce mucus, and this mucus can form pancreatic cysts. Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. 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 ].

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 ]. An MCN can form anywhere in the pancreas but more commonly it forms in the body or tail of the pancreas. As with an IPMN, MCNs have the potential to become cancerous. Diagnosis There are different types of scan that can detect or monitor an MCN or IPMN.

The poorly marginated, invasive nature of pancreatic ductal adenocarcinoma (PDA), the controversies regarding the clinical import of intraductal papillary mucinous neoplasms (IPMN), and the pitfalls introduced by tumor MRI are comparable in identifying malignant behaviour of cystic pancreatic lesions [5].

Majoriteten av patienter med sidogångs-IPMN ska följas tills de blir aktuella för kirurgi, men bara så länge patienten har ett funktionsstatus som tillåter operation (Del Chiaro et al., 2017; European Study Group on Cystic Tumours of the Pancreas, 2018). Some authors believe that MRI in combination with MRCP have the potential to be the first option for optimal management of BD-IPMN and more broadly all cases of IPMN . 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. MRI is usually of more diagnostic value than CT. MRI can show the cystic nature of a pancreatic fluid collection and its internal structure. The MRI shows a pancreatic fluid collection with dependent internal debris typical of walled off necrosis in necrotizing pancreatitis (7). MRI shows a lesion, which consists of multiple small cysts.

Sometimes an IPMN is found during imaging tests that are being done to look for another problem or condition and happen to include the pancreas. In some cases, people with an IPMN may develop acute pancreatitis, which prompts them to seek treatment. 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.
