Dear Sir,

Compliance with ethical standards 

I read with great interest the recent online-first article titled “Fetal posterior cerebral artery duplication, true fetal posterior cerebral artery variation and trifurcation anterior cerebral artery association” by Kaplanoglu et al. [1] published in Surgical and Radiologic Anatomy (E-pub ahead of print, https:​ //doi.org/10.1007/s00276​ -020-02523-​ 6). The fetal posterior cerebral artery duplication has been called “hyperplastic anterior choroidal artery”, its prevalence was reported as 2.3% on catheter angiography [2] and 0.55% on magnetic resonance (MR) angiography [4]. This discrepancy between the prevalence of catheter and MR angiography studies may be due to the low spatial resolution of MR angiography. The authors stated that trifurcation of the anterior cerebral artery (ACA) is a rare variation. Using MR angiography, however, we previously reported that the prevalence of the triplicated ACA as 3.0%, not rare [3]. In addition, there is simple erratum, “vein” is “artery” on the first line of the Discussion.

Conflict of interest  The author declares that I have no conflict of interest.
