title: Progression of mediastinal tuberculosis and superior vena caval obstruction demonstrated by gallium-67 citrate and radiocolloid liver scintigraphy.
abstract: Most causes of superior vena caval (SVC) obstruction are caused by malignant mediastinal neoplasms, especially bronchogenic carcinoma. Less frequently SVC obstruction results from a non-malignant lesion such as mediastinal goiter or tuberculosis. We present a case of mediastinal tuberculosis which progressively enlarged as shown in consecutive Ga-67 citrate studies. As a result, SVC obstruction developed, exhibited by radionuclide SV Cavagram, and demonstrated "hot" spots in the radiocolloid scans.
