Tóm tắt

OBJECTIVE: Cavernous malformations of the brainstem (BSCM) often cause severe morbidity and mortality. Literature is limited for the optimal surgical approach. Our objective is to demonstrate successful use of the posterior median sulcus to access BSCM. METHODS: We present the case of a 20-year-old woman with an exophytic cavernous malformation of the brainstem showing signs of acute bleeding. The lesion, located near the ventricle surface, was successfully excised with entry through the posterior median sulcus. RESULTS: The patient sustained a mild post-operative weakness but no bulbar symptoms. Complete resection was confirmed on MRI. CONCLUSIONS: The posterior median sulcus is a safe route for exophytic lesions of the medulla.
