A pulsatile mass that extended to the proximal femur was found in the right of the groin on physical examination. There was no sign of limb-threatening ischaemia. Blood urea nitrogen was 54 mg/dL and glucose was 168 mg/dL. The patient had unstable cardiac function. Superficial ultrasound showed an approximately 9 cm hypodense cystic lesion. Colour Doppler ultrasound (figure 1) showed that the lesion was connected to the deep femoral artery. Thrombosis was seen in the aneurysm. Additionally, deep vein thrombosis was found in the right superficial femoral vein extending to the knee. There was no flow on Power Doppler examination. Atherosclerotic intimal hyperplasia and enlargement were seen in the orifice of the superficial femoral artery. Contrast-enhanced MR angiography (figure 2) revealed a 10 cm giant aneurysm that was connected to the deep femoral artery (DFA) in the right of the groin. A 5.5 cm thrombosis was seen on the anterior wall of the aneurysm. The patient underwent conventional angiography for treatment. On angiography (figure 3), a giant aneurysm originating in the DFA was seen. Vascular continuity was established on the distal portion of the aneurysm. The distal embolisation was executed with a peripheral microcatheter. Proximal embolisation was attempted with microcatheter retraction. Peripheral coils were placed on the neck of the aneurysm. Subsequently, no blood filling was seen in the lumen of the aneurysm (figure 4). Aneurysms of the DFA are rare clinical entities. They occur in elderly men. Patients with aneurysms present with ischaemic symptoms. Usually, patients with aneurysms have peripheral atherosclerotic disease. Distal venous stasis and thrombosis related to local venous compressions are other possible complications. In our patient, thrombosis was found in the superficial femoral vein. Ultrasound, CT-MR and conventional angiography may be useful for
