ABSTRACT

The intracraneal saccular aneurisms constitute a problem of health and a frequent finding in the autopsies reaching 5% in some series. Nevertheless, the frequency of broken aneurysms is lower of 0,01%. Therefore, a great part of the aneurysms are asymptomatic or produce symptoms by other mechanisms, specially by compression. The area more affected by these injuries is the arteries that make up the polygon of Willis, in tight relation with the visual routes. Our clinical case is a 49-year old patient with good health background that began with progressive loss of the visual acuity of the right eye without other symptoms. On the physical examination right papillary is confirmed with signs of atrophy of the optical nerve and right papillary of the temporary field of the left eye. In the image studies found were not confirmed in the cranial tomography, nor in the Turkish chair. The Magnetic Resonance (RMN) demonstrates the presence of bilateral supraclinoid arterial expansions that can affect the right optical nerve. The exploration of the visual routes is an examination of great value for the diagnosis of neurological affections. The magnetic resonance should be the choice method of election when a compressive injury of the visual routes is suspected, specially around optical quiasma.
