What are the scintigraphic features of superior vena caval obstruction due to substernal non-toxic goitre?
Radionuclide superior vena caval studies in patients with SVC syndrome due to substernal goitre demonstrate a characteristic thyroidal configuration.
May suggest scintigraphic utility in rare SVC syndrome from goitre; leaves open validation and specificity in larger cohorts.
Four men with clinical features of superior vena caval syndrome due to large substernal non-toxic multinodular goitre have undergone radionuclide superior vena caval studies. In all cases the dynamic scintigraphs showed a characteristic thyroidal configuration attributed to the definition of stretched thyroidal veins and their tributaries. Radiocontrast studies of two patients demonstrated the characteristic thyroid configuration. A radionuclide superior venacavogram taken post-thyroid lobectomy in one case showed the features had reverted to normal.

Sy et al. (1982) conducted a case report in Superior vena caval syndrome due to substernal non-toxic multinodular goitre (n=4). Radionuclide superior vena caval studies was evaluated on Scintigraphic features. Radionuclide superior vena caval studies in four men with superior vena caval syndrome due to substernal goitre showed a characteristic thyroidal configuration of stretched veins.
