Double origin and early bifurcation of the anterior inferior cerebellar artery diagnosed by CT angiography.
Due to the technical improvements, anatomical variations of the small arteries, those were previously reported on cadaveric series, can also be evaluated on CT angiography. Absence of the anterior inferior cerebellar artery (AICA) is the most common variation of the AICA. Duplication and fenestration of the AICA can be rarely seen. In this report, two new variations, early bifurcation and double origin of the AICA, were described on CT angiography.
