Background:
Cerebral radiation necrosis (RN) is an uncommon sequela that occurs in up to 25% of irradiated patients. This can occur 6 months to several years after therapy and create symptoms of headaches, focal neurological deficits, seizures, or behavioral changes. Management can involve corticosteroids, antiplatelet drugs, surgery, and hyperbaric oxygen therapy (HBOT). Currently, there is a paucity of literature investigating these therapies for routine use in the pediatric population.
Observations:
A 5-year-old male with a right frontal atypical teratoid rhabdoid tumor previously underwent craniotomy for tumor resection, followed by chemotherapy, radiation, and autologous stem cell transplant therapy. Progressive radiographic changes surrounding the resection cavity were noted on routine surveillance imaging 20 months after the initial craniotomy and 11 months after the completion of radiation therapy. A biopsy ultimately confirmed RN. Due to the patient's previous complications with steroid use, the patient underwent HBOT. This achieved a significant improvement in clinical and radiographic sequelae of RN.
Lessons:
HBOT was utilized successfully for the management of this patient's RN. HBOT should be considered for pediatric patients with cerebral RN as a potential treatment strategy. https://thejns.org/doi/10.3171/CASE24460.
