This case report highlights the use of stereotactic radiosurgery (SRS) as a potential treatment alternative for acinic cell carcinomas (AcCCs) located at the skull base, a region where traditional surgery poses significant risks due to proximity to critical structures. The subject, a 71-year-old male with a history of AcCC, experienced tumor recurrence at the skull base 23 years after initial resection. Following endoscopic surgery, he underwent SRS targeting multiple tumor locations with a prescribed dose of 20 Gy. This approach led to a remarkable 12-year survival without sequela, suggesting that SRS can offer effective local control, preserve function, and extend survival in skull base AcCC cases. This case underscores the need for further research to establish the efficacy of SRS for AcCCs, especially given their propensity for recurrence and metastasis.
