Abstract

Background and Aim: Short-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. Methods: Case series and systematic review. Results: We 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 Conclusion: This 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.
