    Background And AimShort-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and autonomic symptoms (SUNA) are trigeminal autonomic cephalalgias (TACs). The study explores the potential association between SUNCT/SUNA-like headaches and lateral pontine infarctions.MethodsCase series and systematic review.ResultsWe present three cases diagnosed with SUNCT following lateral pontine infarction on magnetic resonance imaging (MRI), along with a review of these cases and 10 others from the literature.Discussion And ConclusionThis review suggests a connection between SUNCT/SUNA-like symptoms and lateral pontine infarctions. The section also delves into the anatomy and pathophysiology of these symptoms, proposing a mechanism involving neural pathway remodelling in the lateral brainstem.© 2024 European Pain Federation ‐ EFIC ®.
