Superior vena cava syndrome arising from a solitary metastasis to an indwelling catheter

We report the case of a 51-year-old woman with a past history of acute myeloid leukaemia and a malignant fibrous histiocytoma who presented with superior vena cava syndrome (SVCS) secondary to an isolated metastasis that originated from her indwelling central venous catheter. This is the first documented case of a solitary sarcomatous metastasis to a catheter. We discuss the clinical evaluation, radiographic findings, and the current literature.
