| Summary: | Craniopharyngiomas can invade surrounding structures, including the optic chiasm and hypothalamus. In such cases, subtotal resection is often preferred to limit perioperative morbidity and mortality; however, subtotal resection is associated with high rates of recurrence. Recurrent craniopharyngioma is typically treated with another subtotal resection and adjuvant radiotherapy. We present a case of a patient found to have a large craniopharyngioma compressing the optic chiasm, hypothalamus and left cavernous sinus. She underwent surgical debulking but developed recurrence shortly thereafter. Subsequently, she underwent a second debulking surgery, followed by fractionated stereotactic radiotherapy (SRT). Results show that she exhibited an impressive response to SRT with further tumor shrinkage, while remaining clinically well. This case demonstrates the efficacy of SRT in salvage of recurrent craniopharyngioma.
