“…MRCP is part of a standard protocol of MRI of the pancreas thanks to its fast and accurate visualization of the pancreatic duct and its alteration. MRCP is an important imaging tool to identify alterations of the pancreatic duct, from benign (e.g., chronic pancreatitis) (Figure 15) to border line (IPMN) (Figure 18) to malignant, which can show the presence of a pancreatic carcinoma even before it is visible on other sequences (Figure 21), and it is useful in the evaluation of cystic tumors of the pancreas [44].

MR is a powerful diagnostic tool in the diagnosis and management of most hepatic and pancreatic diseases. Thanks to its multiple sequences, the use of dedicated contrast media and special techniques, it allows a multiparametric approach able to provide both morphological and functional information for many pathological conditions. The knowledge of correct technique is fundamental in order to obtain a correct diagnosis. In this paper, different MR sequences will be illustrated in the evaluation of liver and pancreatic diseases, especially those sequences which provide information not otherwise obtainable with other imaging techniques. Practical MR protocols with the most common indications of MR in the study of the liver and pancreas are provided.

Pancreatic lesions are more commonly identified nowadays with the widespread use of imaging investigations. Pancreatic lesions are heterogeneous groups of pathologies with different behavior and prognosis. It is quite difficult to differentiate these lesions because of the shared clinical manifestation and the overlapping imaging features of these lesions. We report the case of a 38-year-old woman who presented with a complaint of a 3-month history of epigastric abdominal pain radiating to her back. She reported a gradual increase in the severity of the pain. She described it as sharp in quality and was exacerbated with food intake and was alleviated by oral paracetamol. There was no history of abdominal distension, weight loss, or change in appetite. Apart from asthma, she had no other comorbid conditions or previous surgeries. She was referred to have an abdominal computed tomography scan which showed a large lesion that appears to arise from the head of the pancreas and was cystic with no soft tissue component. The radiological impression was a lymphoepithelial cyst, duplication cyst, pseudocyst from previous acute pancreatitis, lymphangioma, or intraductal papillary mucinous neoplasm. The decision for open surgical removal was decided. The patient underwent laparotomy and the cystic lesion was identified as arising from the pancreatic head. Complete resection of the mass was carried out with no complications. Histopathological examination revealed cystic lesions with the presence of lymphoid cells aggregates peripherally. The lining of the channels was positive for CD31 and was negative for CD34. Such findings conferred the diagnosis of lymphangioma. Lymphangioma is a very rare tumor of the pancreas with non-specific clinical and imaging features. Complete surgical resection of the lesion is the treatment of choice and the prognosis of the tumor is favorable if the tumor was resected completely.

Pancreatic cystic lesions (PCLs) include a broad spectrum of entities, which greatly differ in their malignant potential and may provide a diagnostic challenge. PCLs can be categorised into: pseudocysts; common cystic neoplasms; uncommon cystic neoplasms and tumours with cystic degeneration. Large lesions are usually possible to differentiate, but small lesions’ characterisation is often not possible. This means that many pancreatic cysts remain undetermined and guidelines are needed for follow-up and management. It is important to make distinction between mucinous cystic neoplasms (MCN) and intraductal pancreatic mucinous neoplasms (IPMN), because all MCN should be resected whereas there is time for observation in specific cases of side branch IPMN. With regards to IPMN, guidelines have established features associated with increased risk of malignancy: the “worrisome” features and high-risk stigmata. It should be considered that the presence of an IPMN may portend an increased risk of invasive pancreatic cancer in a different site of the pancreas. The assessment of PCLs should provide imaging features such as cyst morphology or presence of duct communication, and clinical findings including cystic fluid analysis to improve diagnostic accuracy. Radiomics represents an emerging field of interest that could add some information in the future for the differential diagnosis and follow-up of these lesions. The aim of this study was to define a diagnostic approach to PCLs according to the latest guidelines; a review of the latest developments in radiomics regarding PCLs was also carried out.
