Six children with a history of isolated facial nerve dysfunction or dizziness and nausea were treated for brain-stem glioma between 1984 and 1992. Computerized tomography and/or magnetic resonance (MR) imaging showed a focal, uniformly enhancing mass involving the facial nerve nucleus of the pons. All patients underwent biopsy; the histological diagnosis was juvenile pilocytic astrocytoma in five cases. In the remaining case the biopsy was nondiagnostic, although the surgeon believed that the lesion was a glioma. Postoperatively, five patients underwent conventional focal megavoltage radiation therapy (180 to 200 cGy/day) over a period of 5 1/2 weeks to a total dose of approximately 5400 cGy. One child's family refused radiation therapy; she remained well and stable for 4 years, despite persistent facial weakness, and was eventually lost to follow-up review. Four irradiation-treated patients had complete resolution of their tumors on MR images and have had no evidence of neuropsychological or neuroendocrinological deficits during 4 1/2 to 8 years of follow-up evaluation. Patients whose neuroradiological studies show a lesion resembling those in this series should undergo biopsy and, if the histology of a low-grade tumor (in particular, a juvenile pilocytic astrocytoma) is confirmed, should then receive focal radiation therapy with conventional megavoltage dosages.

A 15-year-old boy had onset of unilateral facial weakness. A few days later, he experienced mild vertigo, double vision, and headache. Examination confirmed a peripheral right seventh nerve weakness in addition to an internuclear ophthalmoplegia. The neurologic features suggested a pontine glioma. A T2-weighted MRI scan revealed demyelinating lesions in the pons and in several areas of the cerebrum, including the periventricular region. Subsequent history revealed that he had been diagnosed with Lyme arthritis 7 years earlier while living in Connecticut. The radiographic studies favored a diagnosis of multiple sclerosis. However, studies of blood and cerebrospinal fluid established a diagnosis of Lyme neuroborreliosis.

The purpose of the study was to assess health-related quality of life (HQL) in patients with high-grade malignant glioma of the brain. The EORTC core Quality of Life Questionnaire (QLQ-C30) and a Brain Cancer Module (BCM20) were administered at baseline and several weeks later (follow-up) to 105 patients with either recently-diagnosed (n = 41) or recurrent (n = 64) malignant glioma. In addition, the attending neurologists completed a standard neurological examination, a modified Barthel Activities of Daily Living Index (BADLI) and the Karnofsky Performance Scale (KPS). In a preliminary step, the QLQ-C30 was found to have acceptable reliability (internal consistency and test-retest reliability). Newly-diagnosed patients and those with a KPS of 80-100 had significantly better physical, role and cognitive functioning and global quality of life with less fatigue, visual disorder, motor dysfunction, communication deficit, weakness of both legs and trouble controlling the bladder than did those with recurrent disease and those with a KPS of 50-70. Similarly, those capable of independent activities of daily living, as reported on the BADLI, had higher functioning scores and less fatigue than did those who were not independent. Patients with dysphasia, mental confusion or motor deficit on neurological examination reported significantly lower levels of physical, role, cognitive, emotional and social functioning and global quality of life than did patients not having these difficulties. They also had significantly more symptoms. In patients with deteriorating neurological status between baseline and follow-up, there was a marked decline in cognitive, physical, role, emotional and social functioning and global quality of life and an increase in fatigue. Thus, there are significant differences in HQL between patients with newly-diagnosed and recurrent brain cancer and between patients with differing KPS and BADLI scores. In addition, the HQL scores provide details not provided by the KPS and the BADLI. Deterioration in neurological function is accompanied by significant deterioration in a range of HQL domains and in global quality of life.

We reviewed the clinical records of 149 patients with pathologically proved cauda equina lesions in order to define the relative frequency and clinical presentations of the various diagnoses. The most common pathology was ependymomas (47 patients) followed in frequency by nerve sheath tumors (35 patients), metastases (27 patients), nonependymal glial neoplasms (six patients), meningiomas (six patients), lipomas (five patients), paragangliomas (five patients) and various other diagnoses (19 patients). Mean patient age at presentation for the various lesions included: metastases (51.5 years), nerve sheath tumors (49.7 years), nonependymal glial tumors (46.5 years), paragangliomas (41.2 years), ependymomas (38.3 years), meningiomas (34.7 years), and lipomas (18.4 years). ANOVA showed that the relationship between age and diagnosis for these groups to be statistically significant at a high level (P = 0.002). Low back pain was the most common symptom and occurred in 44 patients. Other symptoms included unilateral lower extremity pain or tenderness (24 patients), bilateral lower extremity pain or tenderness (16 patients), and bilateral lower extremity weakness (16 patients). No relationship between pathologic diagnosis and specific symptoms was found.

Interferons alpha and beta have been reported to cause tumor regression in a small proportion of patients with recurrent glioma. Eflornithine, an irreversible inhibitor of ornithine decarboxylase, reduces cellular polyamine levels and has also been reported to cause tumor regression in patients with recurrent anaplastic astrocytoma and glioblastoma multiforme. In vitro evidence suggests that interferon and eflornithine are synergistic. In this phase II trial, we investigated the combination of recombinant alpha interferon (36 x 10(6) units/m2 subcutaneously days 3 to 7) and eflornithine (2.25 g/m2 QID PO days 1 to 7) repeated every 28 days. All 29 patients entered in the study were evaluable for toxicity and efficacy. Toxicity consisted primarily of fever, chills, myalgia, weakness and fatigue as well as cortical dysfunction including somnolence, confusion, and exacerbation of underlying neurologic deficits. One patient died from cerebral herniation attributable to interferon. None of the patients experienced objective tumor regression. Seven patients (24%) were stable for more than six months, but the disease stability could also be explained by indolent underlying disease or inability to distinguish recurrent tumor from delayed radiation effects. Intermittent high-dose recombinant interferon alpha plus eflornithine demonstrated no definite antitumor effects in this trial.

The toxicity and therapeutic effect of the ventriculolumber perfusion of 3-[(4-amino-2-methyl-5-pyrimidinyl)methyl-1-1(2-chloroethyl)-1-nitros our ea hydrochloride (ACNU) against subarachnoid dissemination of gliomas were studied. Twenty-one patients (6 patients with anaplastic glioma, 7 with glioblastoma and 8 with medulloblastoma or PNET) received ventriculolumber perfusion of ACNU when they were diagnosed as having subarachnoid dissemination. The course of perfusion and cumulative dose of ACNU was 10 times and 95 mg on average, respectively. Most of the patients received systemic chemotherapy in combination with perfusion therapy and some patients with radiotherapy. Response rate was 17% and median survival time after the diagnosis of dissemination was 12 months for anaplastic gliomas, 29% and 12 months for glioblastoma, and 88% and over 25 months for medulloblastoma and PNET. The ventriculolumber perfusion of ACNU was performed for prophylactic purpose in 7 patients with high risk at the early postoperative period in combination with conventional adjuvant therapy. The course of perfusion and cumulative dose of ACNU was 2.3 times and 21 mg on average, respectively. One patient developed subarachnoid dissemination and died 22 months after surgery. Other 6 patients survived without dissemination on median over 29 months after surgery. Side effects encountered were headache in 4 patients, nausea and vomiting in 5, a convulsion in 2, right facial weakness in 1, fecal incontinence in 3 and meningitis in 2. They were all temporary except for facial weakness occurred in one patient. These data suggest that the ventriculolumber perfusion of ACNU is a safe and useful in the treatment and prophylaxis against the subarachnoid dissemination of gliomas.

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.

A 49-year-old woman with 6 months history of body weight loss, muscle weakness, and dysarthria, was found with respiratory arrest and resuscitated in the morning of January 1999. An MRI brain scan revealed diffuse swelling and T2/FLAIR high signal intensity with mild Gadolinium enhancement in the lower pons and medulla oblongata. Although the histological diagnosis could not be obtained, glioma (astrocytoma) was suspected. In the morning of July 3rd she presented sweating and cyanosis. Her arterial oxygen saturation was 18%. When we asked her to breathe more, she kept breathing and oxygen saturation was normalized. However, she could not breathe at all when she fell asleep without stimulation. She was kept under respiratory support for 2 months. Her symptoms improved with fluctuating course after 70 Gy of radiation therapy. Ondine curse is one type of sleep apnea syndrome, defined as the selective disturbance of autonomous breathing. Surgical operation and stroke are the reported causes of this syndrome. Brainstem tumor is relatively common cause for children's Ondine curse. On the other hand, it rarely causes adult's Ondine curse as a main symptom.

Sometimes, the clinical presentation of a brain tumour mimics that of stroke or vice versa, as exemplified in the following three patients. In a 73-year-old patient the initial clinical picture was compatible with a brachial plexus lesion, as the weakness in his right hand appeared to have a traumatic, and not a central nervous system related, cause. When he experienced a focal seizure, the CT scan of the brain revealed a lesion in the motor cortex. This was presumed to be an infarction due to the lack of mass effect and the absence of contrast enhancement. Shortly afterwards the patient deteriorated and a follow-up scan revealed a large contrast-enhancing lesion. During surgery this proved to be a glioblastoma multiforme. A 76-year-old man was suffering from a progressive neurological deficit. An MRI scan of the brain revealed a contrast-enhancing lesion and a chest X-ray revealed an asymptomatic lung tumour; the diagnosis 'brain metastasis' was made. The surgeon removed the lung tumour, which proved to be a carcinoma. Later, when the patient was referred to the neurosurgeon for extirpation of the presumed brain metastasis, the MRI scan revealed that the lesion had decreased in size and no longer exhibited contrast enhancement. The metastasis proved to be an infarction. A 53-year-old man presented with sudden loss of consciousness due to a haemorrhage in the occipital lobe. An angiogram did not reveal a vascular malformation and during surgery no abnormal tissue was seen. The patient almost made a complete recovery. However, several months later he developed an elevated intracranial pressure due to a large occipital high-grade glioma, which had caused the original haemorrhage.

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.
