Testicular tumors manifested as inferior vena cava thromboses. Case reports

Four cases of asymptomatic testicular tumors with inferior vena cava (IVC) involvement are reported. All patients were referred to our hospital with non-specific abdominal pain and abdominal US revealed an inferior vena cava thrombosis. CT showed an IVC thrombus extending from the first to second lumbar vertebrae and also retroperitoneal lymphadenopathy in 3 patients. Scrotal US demonstrated intratesticular tumors. IVC thrombosis may result from asymptomatic intratesticular tumors (single or multiple). Because of that, scrotal US is of paramount importance as a routine screening test in patients who radiographically demonstrate caval thrombosis.
