Abstract.

The aim of the study is to demonstrate a rare case of congenital basilar artery fenestration using neuroimaging methods.A 58-year-old man with an isolated lesion of the right n. oculomotorius was examined with brain MRI/MRA and multimodal neurosonography. A typical fenestration was detected on MRA in the proximal portion of the basilar artery immediately after the fusion of the vertebral arteries. It was correlated with ultrasound pattern – a parallel blood flow image and retrograde flow velocity curves were obtained from the fenestrated segments of a. basilaris. Imaging (MRI/MPA and ultrasonic) methods are useful for noninvasive diagnosis of basilar artery fenestration, which in the past was proved only by conventional cerebral angiography
or autopsy.
