**2. Imagistic studies for metastatic pancreatic lesions diagnostic**

When it comes to the most efficient imagistic study in order to determine the existence of such lesions, computed tomography seems to play an important role, most commonly such lesions being diagnosed as singular, multinodular lesions or as a diffuse infiltration with hypervascular aspect [1]. However, in up to 10% of cases, metastatic lesions of the pancreas might not be seen at standard computed tomography (CT), a positron emission tomography/computed tomography (PET-CT) is being needed. In this case, a diffuse uptake revealed by PET-CT studies might be associated with benign conditions (such as Graves' disease or autoimmune thyroiditis), while focal uptake is rather significant for the presence of a malignant lesion. In such eventualities, a percutaneous biopsy is recommended in order to have a positive diagnostic of malignancy [6].
