Early-onset Symptomatic Radiation Necrosis After Stereotactic Radiosurgery in the Setting of COVID-19 Infection

Radiation necrosis (RN) is the primary dose-limiting treatment-related toxicity following stereotactic radiosurgery (SRS) and occurs in approximately 5-10% of patients with brain metastasis, [1] but is rarely described in patients with benign tumors given the lower doses prescribed for treatment. Several factors have been associated with risk of RN including multiple dose-volume metrics, prior radiotherapy, time from treatment, concurrent systemic therapies, certain regions of the brain parenchyma, histology of the tumor, etc.
