Abstract
BackgroundAneurysms of the deep lower limbs veins are extremely rare. Diagnosis of such conditions may be confusing and suggest the presence of a neoplastic lesion.Case presentationWe herein report a case of a 68-year-old woman who was admitted with a large vein tumour revealed by sonography and computed tomography. A direct phlebography revealed a large venous aneurysm of the right common iliac vein with an adhering thrombus and a large collateral circulation. Anticoagulant treatment and compression with an elastic stocking were initiated because the patient refused surgical treatment. A 2-year follow-up showed no aneurysm growth or thromboembolic complications.ConclusionsWe show herein that conservative management can be effective and safe in cases of this rare condition.

The definition of venous aneurysm is difficult to establish
Summary
Superficial vein aneurysms may be misdiagnosed as inguinal hernias [1]. Venous aneurysms are associated with deep vein thrombosis and pulmonary embolism. On radiologic examination (for example, ultrasound and computed tomography), deep vein aneurysms may be misdiagnosed as neoplastic tumours in the abdominal cavity. An arterial and venous Doppler ultrasound was performed that indicated proper arterial flow and no deep vein thrombosis in the lower limbs. The Doppler ultrasound was followed by a direct phlebography that revealed a large venous aneurysm of the right common iliac vein with an adhering thrombus and a large collateral circulation (Fig. 4). She received anticoagulant treatment for 2 years, and no thromboembolic complications or aneurysm growth has been noted far
