Les anévrismes chroniques rompus contenus représentent une entité extrêmement rare, qui peut faire suite à une rupture d'anévrisme. En effet, la complication la plus à craindre de l'anévrisme est la rupture, qui est souvent mortelle. Toutefois exceptionnellement, il se formera un hématome suite à la rupture, lequel sera contenu par les structures anatomiques avoisinantes; ce qui permettra en outre d'arrêter la fuite. Contrairement à la rupture classique, les signes de choc hémorragique seront absents; remplacés par une simple douleur modérée, et des signes souvent atypiques tels que la lyse du rachis dorsal par l'hématome constitué, découverte à l'imagerie dans notre cas. La connaissance de cette entité est importante, car la rupture chronique nécessite une prise en charge chirurgicale; du fait du risque de rupture ultérieure de l'hématome.
Introduction: An aneurysm is defined as a focal dilatation of a blood vessel involving all three layers of the vessel wall. Behçet's disease is responsible for inflammation of the pulmonary arteries and may conduce to an aneurysm. Fifteen percent of patients with Behçet's disease suffer from vascular involvement that includes pulmonary arteries, peripheral and central veins, peripheral and large arteries. The most common manifestation is the deep venous thrombosis (DVT) around 87%; on the other hand the involvement of the pulmonary arteries reaches 10% of the patients. Case Report: We expose the case of a 31-year-old man, who consulted in emergency for hemoptysis that led to the performance of bronchoscopy and a bronchoalveolar lavage. To enrich the case, a thoracic computed tomography (CT) with and without enhancement and a magnetic resonance imaging (MRI) were conducted. The MRI demonstrated bilateral pseudoaneurysms of the pulmonary artery. The treatment was based on corticotherapy and hemostatic. No complications were noted in follow-up exams.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
