Santos, GLima, TPereira, SMacahdo, E2014-01-092014-01-092013J Neuroimaging. 2013;23(1):115-7.http://hdl.handle.net/10400.4/1629Traumatic intracranial aneurysms are rare lesions, accounting for less than 1% of all intracranial aneurysms. Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm after a gunshot wound, and discuss potential pitfalls found during diagnostic work-up.engLesões CerebraisAngiografia CerebralAneurisma IntracranianoFerimentos por Arma de Fogojournal article
