Intraoperative radiation therapy (IOR) is an ideal means of exterminating residual tumor after surgical resection. In this study, the clinical results of IOR using a Scanditronix Microtron MM-22 were evaluated in 14 patients with malignant glioma, five of whom had recurrent tumors. Between July, 1985 and October, 1986, 11 patients with glioblastoma multiforme (GB) were irradiated 18 times (mean, 1.6 times/case), and three with astrocytoma (Kernohan grade III) underwent IOR once each. The target-absorbed dose at 1 to 2 cm deeper than the tumor resection surface was 15 to 50 Gy. During irradiation, a cotton bolus was placed in the dead space after over 91% of the tumor had been resected. As a rule, external irradiation therapy was also given postoperatively at a dose of 30 to 52 Gy. One patient died of pneumonia and disseminated intravascular coagulation syndrome 1 month postoperatively. The 1- and 2-year survival rates of the remaining 13 patients were 84.6% and 61.5%, respectively; among the 10 with GB, they were 80% and 50%. Generally, the smaller the tumor size, the better the results. There were no adverse effects, despite the dose 15 to 50 Gy applied temporally to the tumor bed. IOR was especially effective against small, localized tumors, but was not always beneficial in cases of large tumors, particularly those with a contralateral focus. The improved survival rate in this series demonstrates that IOR is significantly effective in the "induction of remission" following surgical excision of malignant gliomas.

A case of cryptococcosis simulating brain tumor was reviewed. A 66-year-old female was admitted to our hospital with chief complaint of vertigo, gait disturbance and dysarthria. These symptoms started about one year before admission and worsened. Vomiting and urinary incontinence appeared. Neurological examination revealed left cerebellar ataxia and dysarthria. In plain CT (computerized tomography) irregular ill-defined low density area was noted in the cerebellar vermis and bilateral cerebellar hemispheres. And slight ventricular dilatation was found. Irregular shape of ring-like enhancement corresponding to capsule and patchy or mottled enhancement inside the tumor were seen. Suboccipital craniectomy was performed and yellowish necrotic tumor with hard capsule was removed. Histological diagnosis was not neoplasm or tuberculoma. Postoperatively liver function progressively worsened. She died due to disseminated intravascular coagulation. Autopsy revealed typical liver cirrhosis without malignant change. 3.0 X 2.5 cm sized, slightly hard, yellowish lesion was found on upper part of cerebellar hemispheres. This had extremely necrotic tissue and a great number of cryptococcus neoformans were found. And other intracranial lesion was not confirmed. Finding of pulmonary cryptococcosis was not gained. Our case is very rare because of solitary cerebellar abscess and absence of meningitic episode or pulmonary cryptococcosis. There are three types of inflammation in cerebral cryptococcosis. The commonest manifestation is the meningitic type, the second mode is granulomatous lesion and the third and the least presentation is intracranial abscess formation. CT reveals various findings according to clinical stage. CT findings are those of meningitis, meningoencephalitis, granuloma and abscess. Cryptococcal granuloma or abscess often simulates brain abscess, glioma and metastatic brain tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

To study the morphological changes of anti-Fas antibody-mediated apoptosis in living U251-SP human glioma cells, we employed video-enhanced contrast differential interference contrast (VEC-DIC) microscopy. In our previous study, we investigated the susceptibility of human glioma cell lines to anti-Fas Immunoglobulin M (IgM) antibody. U251-SP cells express Fas antigen on their surface. The cells exposed to anti-Fas antibody underwent apoptotic cell death, as reported previously. In this study, morphological changes of apoptosis characterized by bleb formation, shrinkage of cells, and nuclear condensation were observed under VEC-DIC microscopy in U251-SP human glioma cells treated with anti-Fas antibody. These results demonstrate the usefulness of VEC-DIC microscopy to study the process of apoptotic cell death.
