This was his first CT angiography examination. Currently, he is asymptomatic and is being treated with oral anticoagulants and compression stockings.Images in a 19-year-old man presenting with recurrent bilateral lower-extremity deep venous thrombosis and symptoms of lower-extremity venous insufficiency related to congenital absence of the inferior vena cava. (A) Coronal volume-rendered abdominal CT angiogram shows the cutaneous collateral vessels. (B) Coronal volume-rendered abdominal CT angiogram reconstructions of the paraspinal collateral vessels show absence of the entire inferior vena cava with pelvic (arrows) and retroperitoneal (arrowhead) collateral vessels.Download as PowerPointOpen in Image Viewer The IVC develops between the 6th and 8th week of embryonic life through a series of sequential anastomoses and regression of multiple embryonic veins, including the vitelline vein and the paired posterior cardinal, subcardinal, and supracardinal veins (1,2). Congenital absence of the IVC has an unknown incidence and unclear cause because it is difficult to identify a single embryonic event, but complete failure of embryonic vein development and sequela of intrauterine or perinatal venous thrombosis with atrophy have been suggested as possible causes of this issue (1–3). Furthermore, lower-extremity venous return in these patients occurs by means of enlarged collateral vessels that drain into the ascending lumbar veins and then to the azygos and hemiazygos system. These collateral vessels may simulate paraspinal masses (3). Affected patients may experience symptoms of lower-extremity venous insufficiency or idiopathic deep venous thrombosis (1–3).Disclosures of conflicts of interest: L.d.P.G.d.F.
