neoplasm, solid and pseudopapillary neoplasm, and side-branch and main duct intraductal papillary mucinous neoplasm Highlight the demographics, pathologic appearance, and cyst aspiration profiles characteristic of each lesion Review the malignant potential and management of each lesion TABLE OF CONTENTS/OUTLINE 1. (Right) Coronal CECT demonstrates innumerable pancreatic cysts, compatible with multiple side branch IPMN. No suspicious individual cyst or solid mass was seen, but EUS findings were suspicious, and the patient was found to have invasive carcinoma at surgery. Nov 03, 2015 · Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a fascinating entity caused by proliferation of mucin-producing neoplastic epithelia and characterized by cystic or saccular dilation of the branch duct (BD-IPMN) and/or main duct (MD-IPMN) (1). IPMN indicates intraductal papillary mucinous neoplasm; MCN, mucinous cystic neoplasm; SCA, serous cystadenoma. A CCD was established for each patient, and the cyst was classified as malignant, benign mucinous, or benign nonmucinous using either the histologic diagnosis or a combination of 2 of 3 concordant characteristics: 1) EUS features, 2) cyst fluid CEA level, or 3) cytology (Table 2 ).
IPMN – Intraductal Tumors What is IPMN? IPMN, an acronym for Intraductal Papillary Mucinous Neoplasm, is a cause of pancreatitis in which there is a transformation of the cells that line the pancreatic duct into premalignant cells —cells that display characteristics that may develop into pancreatic cancer— that produce mucous and block off the pancreatic duct. Asymptomatic thin-walled unilocular cystic lesions smaller than 3 cm or side-branch intraductal papillary mucinous neoplasms should be followed up with CT or MRI at 6 and 12 months interval after detection. Mar 24, 2016 · Multiple MR images demonstrate a cystic lesion arising from the pancreatic neck, apparently communicating with the adjacent pancreatic duct, representing a sidebranch IPMN 16BMR8 For more, visit ... Because of the rapid growth of my IPMN, I checked with 3 different doctors, all of whom advised surgery. In Jan 2018, I had a whipple procedure, and I am now in my 5th week of recovery. The pathology report indicated that I do not have cancer, but the doctor felt that it was just a matter of time before my IPMN would become cancerous. Intraductal papillary mucinous tumor (IPMT) of the pancreas is characterized by the presence of mucin-producing tumor and cystic dilation of the branches of the pancreatic duct in the uncinate process (branch duct type), diffuse or segmental dilatation of the main pancreatic duct (main duct type), or dilatation of the main duct and the branch ducts (combined type) (, 1)–(, 3) (,,,, Fig 1). The dilated ducts often contain profuse mucin.
• Side branch IPMN typically hyperintense on T2WI and low signal on T1WI, and can appear unilocular, multicystic, tubular, or as grape-like cluster of cysts Presence of dilated adjacent main pancreatic duct concerning for main duct involvement – MRCP may be more accurate than CT for assessing main duct size and internal mural nodularity Nov 03, 2015 · Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a fascinating entity caused by proliferation of mucin-producing neoplastic epithelia and characterized by cystic or saccular dilation of the branch duct (BD-IPMN) and/or main duct (MD-IPMN) (1).
Sep 14, 2015 · The management of intraductal papillary mucinous neoplasms (IPMN) is presently evolving as a result of the improved understanding of the natural history and biological behavior of the different pancreatic cystic neoplasms; and better preoperative diagnosis of these neoplasms due to advancement in preoperative diagnostic tools.

Intraductal Papillary Mucinous Neoplasm-When to Resect? Joshua A. Waters, C. Schmidt. General Surgery; Research output: Contribution to journal › Article. Because of the rapid growth of my IPMN, I checked with 3 different doctors, all of whom advised surgery. In Jan 2018, I had a whipple procedure, and I am now in my 5th week of recovery. The pathology report indicated that I do not have cancer, but the doctor felt that it was just a matter of time before my IPMN would become cancerous.
Oct 13, 2018 · Intraductal Papillary Mucinous Neoplasm (IPMN) of Pancreas is an exocrine, cystic tumor that grows within the pancreatic duct. IPMN cells are characterized by the secretion of mucus, and are typically located in the head region of the pancreas Mar 31, 2016 · Evaluation of malignant intraductal papillary mucinous neoplasms of the pancreas on computed tomography and magnetic resonance imaging Nieun Seo 1 , Jae Ho Byun 2, * 1 Department of Radiology, Severance Hospital, Yonsei UniversityCollege of Medicine, Seoul, Korea For BD-IPMN, the affected branch ducts are cystically dilated and communicate with the main pancreatic duct. In some occasions, the cystic side branch ducts do not fill with contrast due to mucus plugging. In some cases, duodenoscopy during ERCP reveals a patulous duodenal papilla and mucin extrusion through the orifice. Asymptomatic thin-walled unilocular cystic lesions smaller than 3 cm or side-branch intraductal papillary mucinous neoplasms should be followed up with CT or MRI at 6 and 12 months interval after detection. IPMN is a grossly visible (≥1 cm), mucin-producing neoplasm that arises in the main pancreatic duct and/or its branches. Two different entities were initially identified: the “main-duct” IPMN and the “branch-duct” IPMN (1, 2). Main-duct IPMNs may be associated with contemporary involvement of the side branch ducts; as a Intraductal papillary mucinous neoplasm (IPMN) IPMNs are commonly encountered cystic lesions of the pancreas and can be classified based on involvement of the main duct and side branch. There is the main duct IPMN, side branch IPMN, and combined IPMN (involving both main duct and side branch).
Side-branch IPMN (SB-IPMN). Coronal MRCP shows a cystic dilatation of a side branch in the head of the pancreas, connected with the Wirsung duct Feb 11, 2010 · Side-branch intraductal papillary mucinous neoplasms (IPMN) of the pancreatic head/uncinate are an increasingly common indication for pancreaticoduodenectomy (PD). However, enucleation (EN) may be an alternative to PD in selected patients to improve outcomes and preserve pancreatic parenchyma. Hypothesis Malignant intraductal papillary mucinous neoplasms (IPMNs) can be predicted before surgery. Design Retrospective review of a prospectively collected database. Setting Academic, urban, tertiary care hospital. Patients Sixty-four consecutive patients with a pathological diagnosis of IPMN.
Jan 22, 2010 · Abstract Branch duct intraductal papillary-mucinous neoplasms of the pancreas (BD-IPMN) are being diagnosed with increasing frequency. Although BD-IPMN outcomes are generally good, pancreatic ductal adenocarcinoma (PDA) is found distant from the original BD-IPMN in about 3.3–9.2% of cases.
Main duct IPMN：segmental or diffuse dilation of main pancreatic duct (＞5mm),without a visible obstructing lesion or stenosis. Side branch IPMN：cysts measuring ＞5mm in diameter which communicate with the main pancreatic duct; often seen as grape like cluster of cysts. Most common location is head and neck; often multifocal.
Jun 26, 2013 · Purpose. The aim of our study was to follow the evolution over time of multifocal intraductal papillary mucinous neoplasms (IPMN) of the pancreatic duct side branches by means of magnetic resonance imaging (MRI).
Departments of 1 Radiology, 2 Surgery, and 3 Pathology, G.B. Rossi University Hospital, University of Verona. Verona, Italy. ABSTRACT. Context To present the case of an unusual presentation at imaging of a very small solid undifferentiated pancreatic adenocarcinoma which mimics a side-branch intraductal papillary mucinous neoplasm. In addition, MRI/MRCP is very sensitive for identifying whether a patient has single or multiple PCN, with the latter favouring a diagnosis of multifocal side-branch IPMN.25 33 36 37 Patients with PCN may require lifelong imaging follow-up.
Background & Aims: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas arising in branch ducts are thought to be less aggressive than their main-duct counterparts, and guidelines for their conservative management were recently proposed. Advances in Pancreatic Disease that impact Cytology •Neoadjuvant therapy for pancreatic cancer •Definitive diagnosis required •FNA specimen = only tumor available for that patient after treatment in some cases •Conservative management for most BD-IPMN •New PB terminology and integrated cytology reports support this effort
