Bilateral Breast Enlargement: An Unusual Presentation of Superior Vena Cava Obstruction in a Hemodialysis Patient with Fibrosing Mediastinitis.

67-year-old woman with end-stage renal disease presented with profound edema of both breasts. The presence of a patent hemodialysis basilic transposition fistula and superior vena cava obstruction (SVC), due to fibrosing mediastinitis, was demonstrated by the use of fistulography. Endovascular treatment with a balloon and stent caused immediate resolution of the breast edema. [ABSTRACT FROM AUTHOR]
