The aim of this poster is to review the current literature on most common pancreatic cystic lesions (PCL). The topics addressed are theclassification, the diagnostic accuracy of the images modalities and the management algorithms.

PCLs are increasing in frequency, mainly due to imaging technical improvements. The reported prevalence rates for PCLs using magnetic resonance (MR) varies from 2% to 38% and using computed tomography (CT) has been estimated up 3% [1]. Furthermore, a prevalence of 45% was reported using magnetic resonance cholangiopancreatography (MRCP) [2]. The prevalence increases with age, varying from 8% in patients below 70 years-old to 35% in patients above 90 years-old [3]. PCL form a variegated group of lesions classified according to the arising tissue (epithelial...

The modalities of choice in characterization of PCLs are MDCT and/or MR-MRCP. The diagnostic accuracy reported in literature is 56-85% and 73-91%, respectively [18]. When compared, despite it has been demonstrated the higher ability of MR-MRCP to detect mural nodules (which represent a sign of malignity), ductal communication and wall thickening [1], CT and MRI have not shown significant difference in terms of diagnostic accuracy [2,19] (Fig.1, Fig.2). It is recommended to perform multiplanar reconstructions and curved reformations both in MDCT and MR-MRCP [18]. A...

Current imaging modalities allow differential diagnosis between benign and potential malignant/malignant lesions with high accuracy. It is already demonstrated in literature that in carefully selected patients imaging allows a non-operative management option [18] and therefore avoids the risk of morbidity and mortality associated with surgery, that are not negligible. Indeed, patients initially treated surgically the risk of morbidity reported in literature varies between 27.9% and 36% and the risk of mortality varies between 0 and 1% [24,25]. Gaujoux et al. highlighted also that the risk...
