Brachiocephalic to left brachial vein thrombotic vasculitis accompanying mediastinal pancreatic fistula: A case report

Figure 1 Swelling and redness on the patient’s left arm.

Figure 2 Contrast-enhanced computed tomography image. A: Contrast-enhanced computed tomography image at the level of fluid collection around the head of the pancreas (arrow); B: Contrast-enhanced computed tomography image at the level of the mediastinal pseudopancreatic cyst (arrow); C: Contrast-enhanced computed tomography image at the level of brachiocephalic to brachial vein thrombotic vasculitis with contrast-enhancing vessel walls, suggesting inflammatory changes (arrow).

Figure 3 Contrast-enhanced axial computed tomography image showing the compressed brachiocephalic vein (arrow) with thrombosis between the sternal bone and brachial artery. No mediastinal pancreatic pseudocysts were seen around the structure.
