Collateral circulation from superior vena cava (SVC) syndrome falsely suggests a liver "hot spot"

Collateral circulation from superior vena cava (SVC) syndrome falsely suggests a liver "hot spot"
(A) Contrast-enhanced axial CT image shows a dilated IM vein (arrow) connecting to the portal and hepatic venous circulation to eventually drain into the IVC. This process appears to form an enhancing liver "hot spot" that is actually draining venous blood from the obstructed SVC. Note also the dilated azygos and hemiazygos veins (arrowheads) that connect to the ascending lumbar veins and IVC.
(B) Axial image at the level of the liver shows segmental enhancement of parts of the right and left lobes due to collateral flow from the IM vein.
CT: computed tomography; IM: internal mammary; IVC: inferior vena cava.
