Figure 1 Computed tomography and magnetic resonance imaging. A-D: Case 1; Plain computed tomography (CT) scan shows a round soft tissue shadow in the tail of pancreas with clear boundary and a diameter of 3 cm (orange arrow) (A); Contrast-enhanced CT of abdomen shows a persistent enhancement pattern within the tumor (orange arrow) (B); The T2-weighted image reveals uneven tumor signals, manifesting as a high signal at the edge and a low signal at the center (orange arrow) (C); Contrast-enhanced T1-weighted image clearly displays a mass, with an approximate dimension of 35 mm × 32 mm, that is prominently observable at the pancreatic tail (orange arrow). The solid part of the tumor exhibits enhancement and appears to possess a connection to the pancreatic duct (D); E-H: Case 2; Plain CT scan shows a nodular slightly higher density lesion in the pancreatic-duodenal space, with a clear boundary. The tumor diameter is approximately 3.5 cm (orange arrow) (E); Contrast-enhanced CT of abdomen shows an unevenly enhanced tumor with marked enhancement in the arterial phase, followed by a reduction in enhancement, and an indistinct boundary with the local part of the duodenum (orange arrow) (F); The T2-weighted image reveals that the majority of the tumor exhibits a high-intensity signal, whereas the central portion displays a low-intensity signal (orange arrow) (G); Contrast-enhanced T1-weighted image clearly shows significant edge enhancement (orange arrow) (H).
