The treatment of brainstem cavernoma includes neurosurgery and stereotactic radiosurgery (SRS). We reported two cases with brainstem cavernoma treated with linear accelerator (LlNAC) cone-based stereotactic radiosurgery.CASE 1: A 44 year-old female patient survived from brainstem cavernoma with bleeding into right pons. She recovered her neurological function gradually in months. Another growing cavernoma at left pons was noted by magnetic resonance imaging (MRI) of brain. It was treated with cone-based stereotactic radiosurgery. The prescribed radiation dose was 14 Gy in two fractions. No new neurological deficit was noted after radiosurgery. On the regular follow-up of brain MRI, the cavernoma over left pons remitted gradually, and no cerebral edema related to radiosurgery was observed.CASE 2: A 43 year-old male patient with history of left orbital cavernoma status post operation and radiation therapy in 1997 had a 0.7 cm cavernoma at left ambient cistern of the 4th ventricle roof. Cone-based stereotactic radiosurgery was performed. The prescribed radiation dose was 18 Gy in two fractions. On the regular follow-up brain MRI the cavernoma demonstrated very good treatment response.
