Computed tomography combined with gastroscopy for assessment of pancreatic segmental portal hypertension

Figure 4 A 58-year-old man with a clinical history of IgG4-related hypophysitis (patient 2). A: Signs of IgG4-related disease, including “sausage-like” changes (orange arrow), were observed in the pancreas on plain computed tomography (CT); B: Pancreatic compression causing splenic vein stenosis (orange arrow) was observed on enhanced CT; C: Splenic portal vein dilation was observed (orange arrow); D: Tortuous venous clusters (orange arrows) were observed on enhanced CT; E: On gastroscopy, tortuous "earthworm-like" blood vessels in the fundus of the stomach were observed, along with the "red sign" (blue arrow).
