Radiosurgical treatment of brain tumors is sometimes considered to be free from significant acute complications or adverse effects. A rare case of fatal intratumoral hemorrhage immediately after gamma knife radiosurgery (GKR) for brain metastasis is reported. A 46-year-old woman with lung cancer complicated by systemic dissemination experienced an acute episode of headache, speech disturbances, and right-side hemiparesis. She had no history of arterial hypertension or coagulation disorders. CT and MRI disclosed multiple brain metastases. The largest tumor, which was located in the left frontal lobe and caused a significant mass effect, was removed microsurgically without any complications. GKR for nine residual metastases was done on the fourth postoperative day. The marginal dose, which corresponded to the 50% prescription isodose line, constituted 20 Gy. No complications were noticed during frame fixation, treatment itself, or frame removal. Fifteen minutes after the end of the GKR session the patient acutely fell into a deep coma. Urgent CT disclosed a massive hemorrhage in the left cerebellar hemisphere in the vicinity of the radiosurgically treated lesion. The patient died 4 days later and autopsy confirmed the presence of intratumoral hemorrhage. In conclusion, GKR for metastatic brain tumors should not be considered as a risk-free procedure and, while extremely rare, even fatal complications can occur after treatment.

Optimal management of cavernous sinus hemangiomas remains unclear. Total microsurgical removal of these neoplasms may be extremely difficult due to their rich vascularization. Three cases of cavernous sinus hemangioma treated with low-dose Gamma Knife radiosurgery are presented. Marginal dose varied from 10 to 13 Gy. Treatment planning and radiation dosimetry were done with a goal of conformal and selective coverage of the lesion with 50% prescription isodose line using multiisocenter technique. In all cases significant shrinkage of the neoplasm was marked at 3 months after treatment. Mean volume reduction at 12 months after radiosurgery was 60% (range: 45-75%). In all patients the shrinkage of the neoplasm was accompanied by notable improvement of the preexistent oculomotor nerve palsy. No radiosurgery-related complications were met during follow-up. In conclusion, low-dose Gamma Knife radiosurgery seems to be very effective for management of cavernous sinus hemangiomas, and can be considered as a treatment modality of choice for these lesions.
