Clinical Relapse Observed in Human MS Patient After Gamma Knife Radiosurgery

In a single case report, a human patient with multiple sclerosis (MS) experienced clinical relapse following gamma knife radiosurgery (GKRS) for meningioma. MRI scans revealed new gadolinium-enhancing lesions in both cerebral hemispheres seven months after the procedure, with additional lesions observed one month later, correlating with the relapse.

Why it matters

This case illustrates a potential association between GKRS and MS relapse, highlighting a possible consideration for treatment evaluations in patients with MS undergoing similar procedures.

What this does not prove

The findings are based on a single patient case report, which limits their generalizability and does not establish causation.

Next milestone

No next milestone was established from the available source.
