Takayasu's arteritis (TA) is a chronic inflammatory arteritis, preferentially affecting the major arteries such as the aorta and its main branches. Its course may be biphasic, with an early systemic phase characterised by non-specific inflammatory features and a later stage with occlusive lesion of the affected vessels. We reported 3 patients with TA, who presented very varied symptoms. These cases emphasise the importance of ultrasound image, which can help to establish the diagnosis at very early stage of vasculitis and improve prognosis.
