Gamma-knife radiosurgery (GKS) has become an important treatment modality for meningioma. Recently, however, it has become known that GKS may occasionally be associated with cyst formation following treatment. The present report describes 2 cases of cyst formation associated with meningioma after treatment. From our experience with these 2 cases, we suggest raising awareness of the possible development of cyst after GKS and remind clinicians that a sophisticated decision-making process should be implemented when planning GKS for meningioma.
