Intraductal papillary mucinous tumors (IPMTs) are benign and malignant lesions that arise from the epithelial lining of main pancreatic duct and/or branch pancreatic ducts, with excessive mucin production (especially hyperplastic/adenomatous variety). Based on the degree of cytoarchitectural atypia on microscopic examination, IPMTs are classified a...

Context 1
... ultrasound may reveal one or multiple cystic pancreatic masses or ductal dilatations; however, echogenic mucin may make the tumor indis- tinguishable from the surrounding pancreatic parenchy- ma. Intraoperative sonography allows superior visuali- zation of the pancreaticobiliary system and facilities identification of cystic lesions and mural nodules [19] ( Figure 2). Endoscopic ultrasound (EUS) has a high sensitivi- ty and specificity for the detection of IPMTs, demons- trating a focal or diffuse dilatation of the main pancreas- tic duct, accompanied by mural nodules and pancreatic parenchyma atrophy [20,21] (Figure 3). ...

It has been reported that endoscopic retrograde cholangiopancreatography (ERCP) is of value in evaluating precise pancreatograms of the pancreatic duct (PD). Recently, institutions have tended to perform magnetic resonance cholangiopancreatography (MRCP) for the diagnosis of PD due to post-ERCP pancreatitis (PEP). In small pancreatic cancer (PC), i...

The technological progress within the range of methods of pancreas imaging and their more common accessibility selects a group of patients requiring a microscopic diagnosis. Percutaneous fine needle aspiration biopsy under the control of ultrasonography (PCFNA/USG) is the method commonly used in determining the character of a focal pancreatic lesion.
Aim of the Work
. An assessment of the accessibility of PCFNA biopsy in the assessment of solid and cystic changes in a pancreas and the correlation of the results of imaging examination, cytological smear and concentration of a serous marker CA19-9.
Material and Methodology
. In our material we analysed 43 cases of tumors of the pancreas among the patients who were at the average age of 59 ± 10.4 (14 women, 28 men) diagnosed by PCFNA biopsy.
Results
. In a group we are 23 cases of cancer, 12 cases of inflammation and 7 cases of cellular atypia for which 2 cases of IPMN were included. The sensitivity of the method was 92.5% but specificity was 68%. In our opinion PCFNA/USG is a method of the comparable sensitivity and specificity with fine needle aspiration biopsy with EUS control and its efficiency depends to a considerable degree on experience and interdisciplinary collaboration.
Cystic tumors of the pancreas are a subset of rare pancreatic tumors that vary from benign to malignant. Many have specific imaging findings that allow them to be differentiated from each other. This article aims to review the histopathologic and imaging findings of the relatively common lesions (serous microcystic adenoma, mucinous cystic tumor, intraductal papillary mucinous tumor, and solid pseudopapillary tumor) and uncommon lesions (cystic endocrine tumors, cystic metastases, cystic teratomas, and lymphangiomas) in this group.
