Between May 1992 and February 1994, 213 lesions in 183 consective patients were treated with Gamma Knife radiosurgery at Severance Hospital, Yonsei University, Seoul, Korea. During this period, we experienced 2 deaths, 1 directly and another indirectly related to irradiation. Nonfatal complications included 1 tumor bleeding, and 4 ventriculoperitoneal shunts had to be inserted due to aggravation of preexisting hydrocephalus. Radiation-induced imaging changes developed in 23.6% of the cases followed up for more than 6 months. Among 24 lesions of 8 cavernous hemangiomas, all 4 cases with lesions larger than 1.5 cm3 developed imaging changes.
