Multidetector computed tomography three-dimensional and multiplanar reconstruction diagnosis of a rare cause of gastrointestinal bleeding: A case report

Figure 4 Four-phase dynamic computed tomography features and identifying the bleeding in arterial-phase, portal-phase, equilibrium-phase, and delayed-phase scanning. A: The arterial-phase showed no abnormal signs of the blood vessel on computed tomography images; B: During the portal-phase, the testicular vein and the superior mesenteric vein gathered together with vascular dilatation, tortuosity, and active bleeding (orange circle); C: The equilibrium-phase also showed bleeding; and D: Delayed-phase scanning showed vascular mass enlargement.
