(A) Axial computed tomography in the arterial phase showed dilatation of splenic artery, aneurismal dilation of the splenic vein, and small intra-parenchymal splenic aneurysm. (B, C) Reformatted maximum intensity projection (MIP) and volume rendering techniques (VRT) images in the coronal plane showed tortuous dilated splenic artery and multiple aneurismal dilatation of the splenic vein.

CTA also showed an intrasplenic venous aneurysm, which was presumed to be the location of the fistula (Figure 1A-1C).
(A, B) Angiography showed a splenic arteriovenous fistula.

Subsequently, the patient had a cardiac CT, which showed a large mass arising from the inter-atrial septum and protruding towards the mitral valve, consistent with atrial myxoma (Figure 3A, 3B).
