title: [De novo distal superior cerebellar artery aneurysm after embolization of a ruptured aneurysm at the bifurcation of the contralateral basilar and superior cerebellar arteries].
abstract: The formation of de novo aneurysms in the posterior fossa after successful treatment of a previous aneurysm in the same fossa is rare. Here we describe a case of a de novo generated aneurysm at the distal superior cerebellar artery(SCA)7 years after the successful obliteration of an aneurysm at the contralateral basilar artery(BA)-SCA bifurcation. The treatment of the original posterior fossa aneurysm may lead to hemodynamic changes that may contribute to the formation of a de novo aneurysm at another vulnerable point in the posterior fossa circulation. We conclude that a close surveillance is required after the initial treatment of posterior fossa aneurysms in order to detect the possible formation of de novo aneurysms.
