title: Follicular carcinoma of the thyroid appearing as an intraluminal superior vena cava tumor.
abstract: Follicular carcinoma of the thyroid has the propensity for microscopic angioinvasion. Tumor extension into the great veins has been previously reported primarily as a postmortem finding. Most patients have a long history of a substernal goiter and appear initially with superior vena cava syndrome. We studied a case of intraluminal invasion of the superior vena cava by a follicular carcinoma of the thyroid, without superior vena cava syndrome. To our knowledge, this is the second reported case of a patient treated successfully by surgery.
