Case Reports
Laser-interstitial thermal therapy for refractory cerebral edema from post-radiosurgery metastasis.
Stereotactic radiosurgery is often an effective tool for the treatment of brain metastases. A complication of radiosurgical treatment for brain metastasis can be persistent cerebral edema. Treatments of this refractory cerebral edema include observation, corticosteroids, and surgical resection of the edema-inducing mass. Laser-interstitial thermal therapy is a minimally invasive technique for ablating intracranial lesions. It may provide a treatment option for metastases after radiosurgery causing refractory cerebral edema. ⋯ Laser-interstitial thermal therapy may be a treatment option for refractory cerebral edema after stereotactic radiosurgery to a metastasis. This therapy may be of particular use in deep-seated lesions refractory to corticosteroid therapy.
