T he pathologic and radiologic features of ductectatic mucinous cystadenoma and cystaclenocarci nomaof the pancreashavebeenclarified [1â€"5]. These tumors originate from ductal epithelial cells within the pancreaticduct branches.This entity is characterized by a cystic dilatation of a branchof the pancreaticduct that often contains thick mucin, frequently locatedin the uncinate process of the pancreas [2]. Macroscopically, the lesion is covered with thin pancreatic paren chyma and consists of a conglomeration of com

“…CT scanning was performed in 69 patients with a single-detector row helical CT scanner (HiS- However, more recent studies have found that CT and MRI have diagnostic accuracies ranging from 27% to 96.8% in detecting pancreatic cystic neoplasms, which were lower than expected (13)(14)(15). Although imaging findings and differentiation of pancreatic cystic neoplasms have been reported in many studies, their accurate radiologic differentiation is still difficult due to their overlapping morphologies and their very small sizes for evaluation (12)(13)(14)(15)(16)(17)(18)(19)(20)(21).…”

Purpose:To evaluate the multiplicity and mean number of cystic lesions in patients with branch duct intraductal papillary mucinous neoplasms (BD-IPMNs), serous cystadenomas (SCAs), and mucinous cystic neoplasms (MCNs) of the pancreas. Materials and Methods: Two hundred and eighty-eight patients with pathologically proven cystic neoplasms of the pancreas underwent preoperative CT and/or MRI. These patients were divided into the following three groups: BD-IPMN, SCA, and MCN groups. Two radiologists retrospectively analyzed the CT and MRI examinations to determine the multiplicity (i.e., more than one lesion) and mean number of cystic lesions per patient. Among the three groups, statistical comparison of multiplicity of cystic lesions was performed. Results: The BD-IPMN group consisted of 155 patients with 176 BD-IPMNs, with multiplicity in 15 patients (9.7%) and a mean 1.14 BD-IPMNs per patient (range, 1-3). The SCA group consisted of 67 patients with 69 SCAs, with multiplicity in one patient (1.5%) and a mean 1.03 SCAs per patient (range, 1-3). The MCN group consisted of 67 patients with 67 MCNs, with no multiplicity. Multiple cystic lesions were significantly more common in the BD-IPMN group than in the SCA and MCN groups (p = 0.003). Conclusion: BD-IPMNs were more frequently associated with multiplicity of cystic lesions than SCAs or MCNs of the pancreas.

IPMNs are cystic tumors of the pancreas recently reported with increasing frequency [6,38,41,47,48] . They are macroscopically characterized by having an intraductal origin and growth [49] , with the production of dense mucin that fills the main pancreatic duct (the ductectatic mucin-hypersecreting variant) or with endoluminal papillary proliferation (the papillary-villous variant).…”

The introduction of contrast-enhanced ultrasonography (CEUS) has led to major improvements in the diagnostic capabilities of ultrasound (US). The innovative use of CEUS for study of the pancreas has created the need for a definition of the most frequent dynamic features of solid and cystic masses. CEUS is less expensive compared to computed tomography and magnetic resonance imaging and is able to significantly improve the accuracy of US, allowing better characterization and staging of pancreatic pathologies.
