【Abstract】 Objective To analyze the incidence of intracranial unruptured aneurysms in patients with intracranial artery stenosis, clinical features, and investigate the risk factors for unruptured intracranial aneurysms. Methods Medical records from all patients performed with digital subtraction angiography (DSA) who had been treated at Peking University Third Hospital, China, from January 2012 to December 2015 were retrospectively reviewed to identify cases coexistence with cerebral artery stenosis and unruptured intracranial aneurysm. Results Of 273 patients with cerebral artery stenosis (≥50%), intracranial unruptured aneurysms was observed in 17 cases (6.23%) from age of 45 to 78, among them 8 (47.06%) were female and 9 (52.94%) were male. The incidence of unruptured intracranial aneurysm in male patients was 4.17% (9/216), and that of female was 14.4% (8/57). There was statistically significant difference between the male and female incidence of intracranial aneurysm ( P
