Left internal jugular vein thrombosis due to a lung tumor.

Abstract

Deep vein thrombosis is a common disease among Caucasians but is rare in Asia. Venous thrombosis may be fatal, for example by a pulmonary embolism and right or left atrial thrombosis. Alternatively, deep vein thrombosis may follow a benign pattern such as femoral and popliteal vein thrombosis. Theories abound regarding the causes of deep vein thrombosis, with the most common theories being long-term stasis and lack of exercise. Internal jugular vein thrombosis is a rare but potentially fatal disease with various causes. In the pre-antibiotics era, this disease was frequently associated with deep neck infection. Recently however, local trauma, central catheterization, and repeated intravenous injections with drugs have become the leading causes of thrombosis. Spontaneous internal jugular vein thrombosis may occur in connection with a neoplasm, termed Trousseau's syndrome. This investigation reports a case of lung cancer associated with internal jugular vein thrombosis.
