The present paper reports the case of a young woman who experienced an ischemic stroke due to the spontaneous dissection and occlusion of both internal carotid arteries, with recanalisation one year after the event. It is underlined that this form is not clinically different from the unilateral form, and that it is often associated with a favourable prognosis. In addition to the characteristic angiographic findings, the paper also highlights the importance of the combined use of MR, MR angiography and echo-Doppler imaging during diagnosis and follow up.
