Difficulty with diagnosis of malignant pancreatic neoplasms coexisting with chronic pancreatitis

Figure 1 Enhanced CT scan shows extensive heterogenous mass (arrow) occupying at para-pancreatic region to be involved with adjacent gastric wall and para-ampullary region. Pancreatic duct dilatation is suggested and superior mesenteric vein thrombosis cannot be ruled out (A). multiple heterogenous hepatic lesions are demonstrated (B).

Figure 2 Enhanced CT scan shows multiple, non-enhanced, pancreatic cystic mass (straight and curved arrows) with soft tissue part (A). multiple, hypodense, alveolar patches at bilateral basal lung parenchyma (straight and curved arrows) (B).
