title: Evolving basilar artery stenosis with watershed ischemia.
abstract: Basilar artery stenosis where flow restriction constitutes the main pathomechanism are exceptional. Here, we report a case where the lesion progression was characterized by watershed infarct between the anterior inferior-superior cerebellar arteries and deep pontine arteries, indicating a significant hemodynamic impairment.
