  • Title: Angiographic and scintigraphic findings in fibrosing mediastinitis.
    Author: Moreno AJ, Weismann I, Billingsley JL, Lundy MN, Brown JM, Graham GD, Brown TJ.
    Journal: Clin Nucl Med; 1983 Apr; 8(4):167-9. PubMed ID: 6221853.
    Abstract:
    The clinical and morphologic findings in the case of a 47-year-old man with fibrosing mediastinitis, most probably due to histoplasmosis, are described. Radionuclide angiography demonstrated obstruction of the superior vena cava with collateral vascularization. Computed tomography demonstrated a large calcific mass interposed between the pulmonary artery and superior vena cava suggesting potential pulmonary vasculature involvement. For this reason, pulmonary scintigraphy was performed which showed right lung perfusion and ventilation defects. Radionuclide angiography and pulmonary scintigraphy complement each other in determining the extent of vascular involvement with fibrosing mediastinitis. However, contrast venography is necessary to correctly delineate the anatomy of the obstructed superior vena cava and its collaterals.
