A 48-year-old woman presented with a left cerebellopontine angle mass. Over 93-month period, the patient underwent seven surgeries, two radiosurgeries, and one external beam radiotherapy. The tumor was histologically benign at first operation, but exhibited unusually aggressive behavior after failed radiosurgery demonstrated clinical characteristics of malignancy such as spinal metastasis. gamma knife (GKR) for recurrence despite being located in resectable region. did not respond. Six months sixth surgery, progressive lower extremity paraparesis sensory disturbance below T11 dermatome. Magnetic resonance imaging revealed multiple intradural mass lesions T2, T11-T12, L2 levels. She died 4 diagnosis metastases. Retrospectively, we speculate that if is region Simpson grade I or II resection possible, direct surgery may be safer option than GKR.
