    Anteroposterior left (left) and right (right) ICA angiograms following injections demonstrating the aberrant left A1 segment arising from the paraclinoidal right ICA. Note the small infundibulum arising from the proximal left A1 segment. A2 = left and right A2 segment of the ACA; LA1 = left A1 segment of the ACA; LICA = left ICA; LMCA = left MCA; MCA = middle cerebral artery; RA1 = right A1 segment of the ACA; RICA = right ICA.
