Demonstration of Superior Vena Caval Obstruction and “Hot Spot” on Liver Scan in a Case of Non-Hodgkinʼs Lymphoma

A case of total superior vena cava obstruction and “hot spot” in the liver demonstrated by a radiocolloid liver scan in a case of non-Hodgkinʼs lymphoma of the anterior mediastinum, is presented. The study showed total obstruction of the superior vena cava and the presence of collateral circulation. The patient received radiation therapy, and a subsequent radiocolloid study showed relief of the obstruction and disappearance of the “hot spot.”
