A case of gliomatosis cerebri which clinically presented with a syndrome of intracranial hypertension (ICH), involvement of bilateral sixth cranial nerves, and oppressive holocranial headache of one week of evolution. Cranial MR and CT were performed demonstrating diffuse hypodense cortical-subcortical lesions on tomography and in T1 sequences and hyperdense lesions in T2 sequences with irregular contrast enhancement. Intracranial pressure was measured by ventricular catheter with the appearance of high, maintained pressure waves (Lundberg A waves). Ventricular LCR study and cerebral angiography did not provide additional data. Meningeal and cerebral biopsies showed infiltration by pleomorphous glioma leading to the diagnosis of gliomatosis cerebri. The patient was treated with steroids, hyperosmolar agents, external LCR derivation and tumoral radiotherapy. Nonetheless, the patient dies at six months of initiation of the symptoms. Gliomatosis cerebri should be taken into account in the differential diagnosis of clinical pictures presenting with ICH.

A 25-year-old man with a history of childhood cerebellar glioma treated by surgical removal, radiotherapy and a ventriculoperitoneal (VP) shunt presented with a 5 month history of frontal headaches. Imaging revealed a mass surrounding his shunt, which was surgically removed, with the shunt left in situ. Histopathological examination revealed an atypical and invasive meningioma. A similar case of a meningioma related to a shunt appears in the literature, again in the context of radiotherapy following removal of a previous neoplasm. Copyright 1999 Harcourt Publishers Ltd.

We present the case history of a 23-year-old man who underwent frontal craniotomy followed by radiotherapy for a Grade III anaplastic glioma. Magnetic resonance imaging (MRI) at the 3-month follow-up showed significant tumour response. He became unwell some weeks after the MRI with an upper respiratory tract infection, severe headache and mild right-sided weakness. A computed tomographic (CT) scan showed a very large volume of intracranial gas, thought to have entered via a defect in the frontal air sinus after craniotomy and brought to light by blowing his nose. Intracranial air is frequently present after craniotomy, but it is normally absorbed within 34 weeks. The presence of pneumocephalus on a delayed postoperative CT scan should raise the possibility of a cerebrospinal fluid (CSF) fistula, or infection with a gas-forming organism. Many CSF fistulae require surgical closure in order to prevent potentially life-threatening central nervous system infection and tension pneumocephalitis. Immediate neurosurgical review is advisable.

After adoptive transfer of pre-activated lymphocytes into the operation cavity of glioma patients, tumor regression and improved survival have been reported in some patients. Results were most impressive when bispecific antibodies with tumor x CD3 specificity were also applied. In this study, we attempted to avoid time-consuming pre-activation procedures for adoptively transferred cells by using a combination of bispecific antibodies directed to the EGF receptor (EGFR) on tumor cells and to CD3 and CD28 on T cells. Eleven patients with high-grade malignant glioma received 3 injections of 2 bispecific antibody fragments (EGFR x CD3 and EGFR x CD28) together with freshly isolated autologous lymphocytes via an Ommaya reservoir. Intracavitary fluid aspirated during immunotherapy was examined for markers of T-cell activation. Increased levels of soluble IL-2 receptor and TNF-alpha were detected in the intracavitary fluid of all patients tested. Two of the 11 treated patients experienced a beneficial response to therapy as defined by a transient contrast enhancement in subsequent MRI scans and prolonged survival. Side effects were transient and consisted of fever, nausea, headache and aggravation of pre-existing neurologic deficits. These adverse effects were most likely due to the antibody construct containing anti-CD3 specificity. Two patients developed cerebral edema and required steroid treatment.

An autopsy case of a patient with diffuse brainstem glioma associated with Laurence-Moon-(Bardet-)Biedl syndrome is described. The subject was a 25-year-old woman who had been suffering from mental retardation, pigmented retinopathy, obesity, hexadactyly, amenorrhea and renal cysts. She developed dizziness, headache and consequent consciousness disturbance. Magnetic resonance images disclosed marked swelling of the pons without contrast enhancement. By means of combined chemotherapy and radiation, she survived for 15 months. Histopathological diagnosis for postmortem specimens obtained from the brainstem was glioblastoma multiforme. No pathogenetic association between the syndrome and brainstem gliomas is known, and the literature contains no cases of patients with this coincidence.

With the exception of patients with neurofibromatosis type II, pediatric extraparenchymal cerebellopontine angle (CPA) tumors of any sort are extremely rare. Most gliomas encountered in the CPA in either children or adults involve the CPA as exophytic extensions of primary brain stem and/or cerebellar tumors. We encountered an unusual case of a giant CPA pilocytic astrocytoma arising from the proximal trigeminal nerve, completely separate from the brain stem. A nine-year-old girl with no evidence for any neurocutaneous syndrome, presented with headaches, mild obstructive hydrocephalus, trigeminal hypesthesia and a subtle peripheral facial paresis. Pre-operative neuroimaging suggested a petroclival meningioma. The tumor was completely resected via a right pre-sigmoid, retro-labyrinthine, subtemporal, transtentorial ('petrosal') approach, using intraoperative neurophysiological monitoring, with minimal morbidity. This appears to be the first reported case of a pediatric primary CPA glioma and the seventh reported case of primary CPA glioma, overall. It represents the second reported case of a primary CPA pilocytic astrocytoma. Given the findings in this case and the six other cases of primary CPA gliomas reported in the literature, as well as the results of histological studies of normal cranial nerves, we hypothesize that the point of origin of these rare and unusual tumors is the root entry zone of the involved cranial nerves. The differential diagnosis of primary CPA tumors should be expanded to include cranial nerve root entry zone primary CPA gliomas.

Gliomatosis cerebri (GC) is a rare disease loosely defined as a diffusely infiltrating glioma involving extensive areas of the brain. The prognosis is poor and no definite treatment has proven effective for GC. Little information exists regarding the role of radiation therapy (RT) for GC, but some researchers have suggested that it is a good choice of treatment from their limited experience. In this report, we present a case with imaging and histological diagnosis of GC and demonstrate the treatment results of RT. The patient was a 39-year-old woman with progressive symptoms of dizziness, unsteady gait, headache, vomiting, and consciousness disturbance for 6 months. She received a series of radiographic examinations and surgical interventions for diagnosis. The definite diagnosis of GC was made by a combination of magnetic resonance imaging (MRI) findings and histological examinations. Forty Gray (Gy) of whole brain irradiation followed by 14 Gy reduced-field boosts were given to her. The MRI, following treatment, showed regressive changes, and clinical symptoms were slightly improved. The patient survived 19 months after the diagnosis, which is longer than the average survival time of patients without treatment.

Glioma is one of the most common brain tumors but the outcome of treatment is still uncertain. The author conducted this study to find the prognostic factors affecting the outcome. The medical records of 41 patients, diagnosed as having glioma, admitted to the Neurosurgery Division, Prasat Neurological Hospital, between January 1998 and December 1999 were retrospectively reviewed. Gender, age, history of smoking and alcohol drinking, symptoms and signs, CT and MRI findings, underlying pathology, locations of lesions, treatments and outcomes were analysed. There were 20 males and 21 females with ages ranging from 2 to 75 years. The mean age was 39.78 +/- 19.81 years old. The three most common presenting symptoms were headache, motor weakness, and seizures. The predominant location of the tumors was in the cerebral hemisphere. Most low grade astrocytoma show low/iso-density with slight contrast enhanced in CT scan. The patients were divided into two groups according to the outcome, improved and dead. Gender, age, history of smoking and alcohol drinking, location of tumors did not have any effect on the outcome. The factors affecting the outcome of treatment were histological subtypes and types of treatment. There was a statistically significantly better outcome in low grade astrocytoma and tumor removal with irradiation. The overall mortality was 21.95 per cent after two years.

Brain tumours should be considered when patients present with headache with diurnal variation, seizures, or progressive neurological symptoms. Spinal cord compression by tumour is a medical emergency. Prognosis for patients with glioma is better in those with tumours of low grade, and in patients younger than 50 years and with higher functional levels. Surgery, radiotherapy and chemotherapy can improve survival for patients. Anticancer therapies can have neurotoxic side effects.

In contrast to childhood brainstem gliomas, adult brainstem gliomas are rare and poorly understood. The charts of 48 adults suffering from brainstem glioma were reviewed in order to determine prognostic factors, evaluate the effect of treatment and propose a classification of these tumours. Mean age at onset was 34 years (range 16-70 years). The main presenting symptoms were gait disturbance (61%), headache (44%), weakness of the limbs (42%) and diplopia (40%). Four patterns were identified on MRI, representing non-enhancing, diffusely infiltrative tumours (50%), contrast-enhancing localized masses (31%), isolated tectal tumours (8%) and other patterns (11%). Treatment consisted of partial resection (8%), radiotherapy (94%) and chemotherapy (56%). Overall median survival was 5.4 years. On univariate analysis, the following favourable prognostic factors were identified (P< 0.01): age of onset <40 years, duration of symptoms before diagnosis >3 months, Karnofski performance status >70, low-grade histology, absence of contrast enhancement and 'necrosis' on MRI. On multivariate analysis, the duration of symptoms, the appearance of 'necrosis' on MRI and the histological grade of the tumour remained significant and independent prognostic factors (P< 0.05). Eighty-five percent of the tumours could be classified into one of the following three groups on the basis of clinical, radiological and histological features. (i) Diffuse intrinsic low-grade gliomas (46%) usually occurred in young adults with a long clinical history before diagnosis and a diffusely enlarged brainstem on MRI that did not show contrast enhancement. These patients were improved by radiotherapy in 62% of cases and had a long survival time (median 7.3 years). Anaplastic transformation (appearance of contrast enhancement, 27%) and relentless growth without other changes (23%) were the main causes of death. (ii) Malignant gliomas (31%) occurred in elderly patients with a short clinical history. Contrast enhancement and necrosis were the rule on MRI. These tumours were highly resistant to treatment and the patients had a median survival time of 11.2 months. (iii) Focal tectal gliomas (8%) occurred in young patients and were often revealed by isolated hydrocephalus. The course was indolent and the projected median survival period exceeded 10 years. In conclusion, adult brainstem gliomas are different from the childhood forms and resemble supratentorial gliomas in adults. Low-grade tumours have a clinicoradiological pattern that is so characteristic that the need for a potentially harmful biopsy is debatable. The optimum timing of treatment for supratentorial low-grade tumours remains unclear. In high-grade gliomas, the prognosis remains extremely poor despite aggressive treatment with radiotherapy and chemotherapy.
