RESUMO
La hemorragia subaracnoidea perimesencefálica se refiere a la presencia de sangre alrededor del mesencéfalo y angiografía normal, cumpliendo con criterios clínicos y radiológicos bien establecidos. A diferencia de la hemorragia subaracnoidea de causa aneurismática, presenta un buen pronóstico, siendo la recuperación, en la mayoría de los casos, completa y satisfactoria. Por otra parte, entre el 2 y el 5% de la población desarrollará un aneurisma intracraneal en el curso de la vida, la mayoría de ellos asintomáticos, siendo posible encontrar un aneurisma incidental en pacientes que han sufrido una hemorragia perimesencefálica. La importancia de un diagnóstico adecuado regirá la conducta a seguir planteando un reto para los equipos de tratamiento vascular, debiendo analizar pormenorizadamente los hallazgos e individualizando las decisiones terapéuticas (AU)
A perimesencephalic subarachnoid hemorrhage refers to the presence of bleeding around the midbrain with a normal angiography, meeting the well established clinical criteria and radiological criteria. Unlike the aneurysmal subarachnoid hemorrhage, it has a good prognosis, the recovery in most cases being complete and satisfactory. On the other hand, between 2 and 5% of the population will develop an intracranial aneurysm in the course of their life, most of them asymptomatic, with the likelihood of finding an incidental aneurysm in patients who have suffered a perimesencephalic hemorrhage. The importance of a proper diagnosis governs the course to follow, being a challenge for vascular treatment teams who must analyse the findings in detail and individualize treatment decisions (AU)
