RESUMO
The diagnosis of vascularitis should be proposed when a concentric and regular thickening of the wall of the aorta or one of its branches is observed or when there is late enhancement of the arterial wall, on sites which are usually free from atheromatous lesions and in a young patient. The radiologist must be aware of the associated clinical signs: oral and genital ulcerative lesions in the Behçet syndrome; finger necrosis in a young male smoker in Buerger disease; hip and shoulder arthropathy and headache in a 70 Year old female and Horton disease; pulseless upper limbs and inflammatory syndrome in a young adult for the Takayasu arteritis. The diagnosis of popliteal entrapment or adventitial cyst should be proposed in young patients without atheromatous lesions.

The present case illustrates the value of multidetector CT scan and cardiac MRI for the diagnosis of a hydatid cyst of the interventricular septum of the heart. These new modalities can help both for surgery planning and follow-up.

Follow-up color duplex sonography after arterial surgery or angioplasty for lower limb arterial disease evaluates the outcome of the procedure and searches for lesions compromising patency. The various types of lesions are described. After surgical bypass, lesions include stenosis, anastomotic abnormality (enlargement, false-aneurysm), arterio-venous fistula, intrinsic bypass abnormalities, and collections. After endoluminal treatment, the main lesions include residual stenosis, restenosis, and in-stent hyperplasia. Local complications related to arterial puncture are described. The frequency and the type of lesions encountered depend on the interval between the date of the revascularization and the follow-up examination.
