[Alcohol injections for the treatment of recurrent intracerebral gliomas].

Seventeen patients with recurrent intracerebral gliomas were given alcohol injection percutaneously guided by ultrasonography. These patients suffered from supratentorial tumors and were operated on previously. The fluid of cystic lesions of 13 patients was aspirated and absolate alcohol was injected for 5-8 times. The cystic cavities soon disappeared followed by symptoms of intracerebral hypertension. Biopsies from different parts of tumor cavity showed that tumor cells were degenerated and necrotized. There was no curable effect on larger solid neoplasm and deep sited solid tumor. We conclude that percutaneous alcohol injection is effective in the treatment of recurrent gliomas.
