Successful use of frameless stereotactic radiosurgery for treatment of recurrent brain metastases in an 18-month-old child

Abstract

There are very few reported cases of stereotactic radiosurgery (SRS) delivered in children under 3 years of age. We report an 18-month-old boy with metastatic recurrence of undifferentiated round cell sarcoma to the brain which was treated with chemotherapy, resection and robotic frameless SRS. Frameless SRS was delivered without technical difficulties, acute adverse events, or clinical sequelae 1.5 months post-radiation. Longer term follow-up will be needed to evaluate local tumor control and effects on neurocognitive development, endocrine function and growth. This report adds to the literature of the few reported cases of successfully attempted SRS in very young children.
