BACKGROUND AND PURPOSE:
Charcot-Bouchard aneurysms (CBAs) are tiny aneurysms arising from small perforating arteries. Despite the potentially catastrophic consequences of rupture of these aneurysms, the existence and prevalence of CBAs are controversial. The literature in this area is sparse with most previous studies based on radiologic case reports of single hemorrhage or histopathologic analysis. 7T MRI provides higher spatial resolution than 3T MRI, which enables imaging of the small perfora…
