Clazosentan-induced reversible focal brain edema in basal ganglia following aneurysmal subarachnoid hemorrhage treatment: illustrative case

Clazosentan can cause reversible localized vasogenic brain edema in the basal ganglia following subarachnoid hemorrhage treatment. This rare but significant complication underscores the importance of careful neurological monitoring and timely imaging in patients receiving clazosentan. Further research is required to understand the risk factors and mechanisms underlying this phenomenon. https://thejns.org/doi/10.3171/CASE24567.
