what does findings consistent with developmental anatomic variants involving the anterior and posterior circulation including hypoplastic A1 segment of right ACA with A2 segment supplied by the left ACA, hypoplastic P1 segment of the right PCA with the right P2 segment supplied by a patent right posterior communicating artery, and hypoplastic right PICA mean in MRA of brain?
His am Chat Doctor. I have read your query. These are blood vessels to the brain. There is a reduction in the caliber of blood vessels mentioned in the report. That is what it is supposed to mean. You need not worry, it's often a normal variant, and you are getting blood supply from other sources. Best of luck,
