Preoperative images: a Contrast-enhanced computed tomography (CT) reveals a 3.6 × 3.4 cm² intrapancreatic hypodense mass (white arrow) close to the splenic artery (SA). b CT shows dilation of the calcified SA (white arrow). c Magnetic resonance angiography shows a hematoma (white arrow) close to the protruding SA. d The proximal SA is divided into two lumens. e, f CT Angiography confirms isolated splenic artery dissection (SAD) with a typical “double-lumen” sign (white arrows). The SA was partially thrombosed in the proximal segment
