Retroperitoneal cavernous hemangioma resected by a pylorus preserving pancreaticoduodenectomy

Figure 1 12 cm × 9 cm tumor was detected by computed tomography and magnetic resonance imaging. A: Abdominal enhanced computed tomography in early phase showed tumor without marked contrast. The tumor had pushed the pancreas to the ventral side; B: T1-weighted image of magnetic resonance imaging showed low and relatively high intensity area inside the tumor; C: T2-weighted image showed high intensity area with a few part of intermediate signal intensity area. IVC: Inferior vena cava.
