Onion Skin Pattern of Facial Sensory Loss in Central Pontine Hemorrhage

Year: 2025

Type: article

Abstract: Results: We report a case of central pontine hemorrhage presenting with pinpoint pupils and a unique “onion-skin” pattern of facial sensory loss. Conclusions: This distribution of sensory loss reflects selective rostral involvement of the spinal trigeminal nucleus, in contrast to the segmental distribution seen with trigeminal nerve involvement. These findings may serve as a localizing sign of pontine pathology on clinical examination.
