Intravascular Lipoma of the External Iliac Vein and Common Femoral Vein

Femoral sheath lipoma causing venous obstruction syndrome

“…They may either cause obstruction by direct extrinsic compression 1,4 or they originate from the vessel wall and cause intraluminal flow impedance. 3,5 In our case, the lipoma was contained within the fairly nonexpandable femoral sheath and, therefore, produced a significant compression effect to venous flow in the common femoral vein resulting in leg swelling.…”

Intravascular lipoma from iliofemoral tract

“…This is the second case affecting iliac vein reported in the literature. Our review found two cases of intravascular lipoma arising from the wall of the left common femoral vein [2,3] and an only case from the wall of right external iliac vein [4]. Other primary tumors originating from vein walls are also rare; these include leiomyomas and leiomyosarcomas [7], hemangiomas [8] and angiosarcomas [9].…”

“…A computerized search was made in Medline matching the keywords ''intravascular neoplasm, veins, femoral vein, iliac vein'' and ''lipoma''. Lipomas arising within vein are rare and usually have been described in association with the involvement of inferior vena cava except that three cases [2][3][4]. Intravascular lipoma involving the superior vena cava is very rare [5,6].…”

Extraluminal lipoma with common femoral vein obstruction: A cause of chronic venous insufficiency

“…Intravascular lesions are found in the inferior vena cava, external iliac, CFV, brachiocephalic vein, and the heart. [7][8][9] There are only three cases of extravascular lipomas causing venous compression and presenting with venous thrombosis. Rubegni et al 10 report a recurrent superficial thrombophlebitis involving the left thoracoepigastric vein attributed to a benign abdominal lipoma in a 48-year-old woman without any other risk factor for thrombosis.…”

“…[4][5][6] Venous wall lipomas are rare and have been described in the inferior vena cava, the superior vena cava, the common femoral vein (CFV), and the brachiocephalic veins. [7][8][9] We report an extravascular lipoma compressing the common femoral vein found in a patient presenting with CVI.…”
