Alejandro Cherro Chief of the Department of Hemodynamics, Clínica Adventista Belgrano, Buenos Aires City, Argentina Extracranial internal carotid artery aneurysms are rare and usually asymptomatic, and their diagnosis can be incidental. We present the case of a young patient with an aneurysm in the cervical segment of the right internal carotid artery (C1 segment), which caused persistent headache. Treatment consisted in an endovascular approach with coil embolization and a closed-cell stent (WALLSTENTTM). Complete aneurysm exclusion was successfully achieved without complications. This case highlights the role of endovascular treatment as an effective and minimally invasive option for this rare pathology. : internal carotid artery aneurysm, saccular aneurysm, embolization, endovascular treatment http://www.raci.com.ar/contenido/art.php?recordID=Mjk0Mg== http://recursos.meducatium.com.ar/contenido/articulos/37200650067_2942/pdf/37200650067.pdf
