Abstract

Spontaneous intra-aneurysmal thrombosis occurs in approximately 50% of giant intracranial aneurysms. The incidence of this process is associated to location, size, and origin, and the natural history of spontaneous thrombosis occurrence in non-giant aneurysms is rare and still unclear. We describe two non-giant middle cerebral artery (MCA) aneurysms that spontaneously thrombosed and comment the aspects of the literature.

Resumo

Trombose intra-aneurismática espontânea ocorre em aproximadamente 50% dos aneurismas intracranianos gigantes. A incidência é associada a localização, tamanho e origem, e a história natural da ocorrência de trombose espontânea em aneurismas não gigantes é rara e ainda indefinida. Descrevemos dois aneurismas de artéria cerebral média com trombose espontânea e comentamos os aspectos da literatura.
