BackgroundArteries that anastomose with the posterior inferior cerebellar artery (PICA) can harbor aneurysms.Case DescriptionWe present a case of a patient who suffered a subarachnoid hemorrhage as a result from an aneurysm on the left lateral spinal artery (LSA) that anastomosed to the PICA. The aneurysm was treated surgically, and the flow between the LSA and PICA was disrupted. The activated anastomotic network created a new anastomosis between the LSA and PICA, which was seen at 6 months' follow-up.ConclusionsCareful follow-up is warranted in patients who have an activated anastomotic network because they can potentially develop aneurysms on newly created anastomoses.Copyright © 2018 Elsevier Inc.
