AB  - BACKGROUND: Fetal-type posterior cerebral arteries (F-PCAs) might result in 
      alterations in hemodynamic flow patterns and may predispose an individual to an 
      increased risk of posterior communicating artery aneurysms (PCoAAs). OBJECTIVE: 
      To determine the association between PCoAAs and the presence of ipsilateral 
      F-PCAs. METHODS: We retrospectively reviewed the radiographic findings from 185 
      patients harboring 199 PCoAAs that were treated at our institution between 2005 
      and 2015. Our study population consisted of 4 cohorts: (A) patients with 171 
      internal carotid arteries (ICAs) harboring unilateral PCoAAs; (B) 171 unaffected 
      ICAs in the same patients from the first group; (C) 28 ICAs of 14 patients with 
      bilateral PCoAAs; and (D) 180 ICAs of 90 patients with aneurysms in other 
      locations. We then determined the presence of ipsilateral F-PCAs and recorded all 
      aneurysm characteristics. RESULTS: Group A had the highest prevalence of F-PCAs 
      (42%) compared to 19% in group B, 3% in group C, and 14% in group D (odds ratio 
      A : B = 3.041; A : C = 19.626; and A : D = 4.308; P < .001). PCoAAs were 
      associated with larger diameters of the posterior communicating arteries (median 
      value 1.05 vs 0.86 mm; P = .001). The presence of F-PCAs was associated with 
      larger sizes of the aneurysm necks (median value 3.3 vs 3.0 mm; P = .02). 
      CONCLUSION: PCoAAs were associated with a higher prevalence of ipsilateral 
      F-PCAs. This variant was associated with larger sizes of the aneurysm necks but 
      was not associated with the sizes of the aneurysm domes or with their rupture 
      statuses.
