some of them with intra cardiac extension and their differential diagnosis. Recognize filling defects that affect the inferior vena cava. Emphasize the importance of a correct diagnosis for staging and surgical intervention planning.
Tumors that arise from the inferior vena cava are extremely rare,
with metastatic involvement being the most frequent.
the most common tumors are leiomyosarcoma and leiomyoma (75% and 15% of tumors arising from large veins,
Malignant involvement is more often attributable to direct endovascular extension and/or intraluminal thromboembolization.
Cardiac extension is a characteristic that changes staging,
treatment and prognosis. Wesuggest the following approach to...
Findings and procedure details
We described four Fundación Clínica Shaio cases,
all evaluated with volumetric acquisitions in multiplanar images,
using a MDCT (320 channels) after the injection of 75 cc of iodinated nonionic contrast media. We found two cases of clear cell renal cell carcinoma,
a leiomyosarcoma arising from the abdomen and a leiomyoma arising from the vessel wall,
all cases were biopsy proven. CASE 1: Leiomyosarcoma 47 years old male with two month history of epigastric pain and weight loss. Fig 8 and 9....

the radiologist should be able to differentiate between a tumor thrombus and a bland thrombus,
suggest the extension,
and determinate the primary or secondary origin of the lesion if it is possible as this information has a direct impact on staging and management.
