Primary brainstem hemorrhage manifests rapidly and is linked to poor prognosis, boasting a high fatality rate. It is an acute and lethal neurological disorder. With a hemorrhage volume exceeding 5 mL, the mortality rate reaches around 90 %, and it nears 100 % with a volume surpassing 10 mL [1]. The risk of brain hemorrhage consistently rises with increasing age. However, it frequently occurs in middle-aged patients, with the highest incidence observed among individuals aged 40 to 60 [2]. The brainstem, being relatively small and situated beneath the cerebellum and below the cerebrum, governs vital functions such as regulation of circulation, respiration, and digestion, serving as a paramount life center.
