Unicentric Castleman disease was misdiagnosed as pancreatic mass: A case report

Figure 2 The lesion was further evaluated by computed tomography and magnetic resonance imaging. A: Magnetic resonance imaging (MRI) showed a lesion of isointensity (white arrow) located above the pancreas body (stellate) which was clearly separated from the normal pancreas; B: Contrast-enhanced -MRI revealed that the edge was enhanced in the arterial phase, and the degree of internal enhancement in each phase was lower than that of the pancreatic parenchyma; C: Computed tomography (CT) showed a nodule of mixed density (white arrow) located above the pancreatic body, which was convex and shallowly lobulated, measuring approximately 37 mm 25 mm in maximum dimensions; D: Contrast-enhanced CT showed uneven progressive enhancement, and the degree of enhancement in each stage was lower than that of pancreatic parenchyma.
