The radiological characteristics of intraventricular tumors were studied with special reference to differential diagnosis from paraventricular tumors by careful analysis of seven cases intraventricular tumors and five cases paraventricular tumors. As, in the radiological term, intraventricular tumors have been dividied into two groups according to their location by Bernasconi et al., seven cases intraventricular tumors reported in this paper were also divided into two groups; 1) 2 cases ependymom occupying the frontal horn and the body of lateral ventricle, 2) 4 cases meningioma and one plexus papilloma occupying the trigone and the adjucent regions. In case of tumors belonged to group 1, the filling defect showing the circumference of tumors and the associated unilateral hydrocephalus were characteristic findings on the ventriculogram, while the depression of ventricular wall was observed in paraventricular tumors. Angiographic characteristics in group 1 tumors were the splay of subependymal veins of the medial group from those of lateral group and the increased density of deep veins due to raised circulation, and these findings demonstrated in all cases of ependymoma reported here. On the other hand, in all meningiomas belonged to group 2, the hypertrophia of choridal arteries was noticed in the angiogram. Moreover, the anterior choroidal artery was shown to be divided into two branches at its plexal segments, and the tumor stain at the trigone always lied between these two branches. We named this dissociation of these two plexal branches due to tumor as "flare sing". This is considered to be specific finding for a trigone meningioma, and this "flare sing" was observed in all of our 4 cases meningioma. In two cases out of four, the inferior ventricular vein was displaced anteriorly delineating the anterior margin of the tumor. This again is considered as a sign indicating the tumor occupying the trigone and adjacent regions.

We describe an unusual case of a giant pericallosal artery aneurysm, producing psychomotor depression from mass effect, associated with a smaller aneurysm of the anterior communicating artery, a dural arteriovenous fistula, and a meningioma. Magnetic resonance imaging (MRI) and cerebral angiography demonstrated the giant aneurysm and the meningioma. Cerebral angiography provided a detailed appreciation of the cerebral circulation, including both aneurysms, the dural arteriovenous fistula, and the potential collateral supply to the involved anterior cerebral distribution. The anterior communicating artery aneurysm was successfully clipped as was the distal anterior cerebral branch supplying the giant aneurysm before its resection. The patient made a full recovery but with persisting, slight dysphasia. We conclude that computed tomography, cerebral angiography, and MRI are of specific value in the assessment of giant aneurysms, but only angiography can provide detailed characterization of the aneurysm and demonstrate other possible cerebrovascular pathology such as multiple aneurysms and arteriovenous fistulas.

RU-486 or mifepristone is best known as an antiprogestin and an abortifacient, but it has broad medical applicability. The drug is also a potent blocker of corticosteroid receptors, and it has shown promise in the treatment of breast cancer, inoperable meningioma, and cushing's disease. Cushing's is a model for the symptomatology of aging which may involve enhanced response to corticosteroid. RU-486 has reversed the osteoporosis, thinning of skin, muscle atrophy, obesity, adult onset diabetes, depression, hypertension, and immunosuppression associated with this disease. RU-486 may be of value in aiding cervical dilation, lactation, and the treatment of endometriosis. In addition, breast, bowel, kidney tumors, hepatomas, endometrial cancer, and fibrosarcomas can show corticosteroid dependency, suggesting that RU-486 may have clinical value against inoperable tumors. In a preliminary 1987 phase I study, in estrogen-positive, chemotherapy-refractory breast cancer patients in Montpelier, France, Ru-486 produced objective tumor regression (6 of 22) that was prolonged (3 months) in 4 patients. Clinical relief of bone pain was observed in 7 of 23 patients with a decline in carcinoembryonic antigen (CEA) tumor makers in 8 patients. Growing in vitro data also show that RU-486 can directly inhibit breast cancer cell proliferation. RU-486 has application for HIV infection, based on data that there is a serum factor in AIDS patients that enhances corticosteroid lympholysis. IN addition, the immune restorative action of RU-486 suggests that it could counteract the immunosuppression seen in aging, in cancer, or in viral or stress-related disease, which has recently focused clinical attention on its potential in the treatment of senile dementia and depression. Scientific conferences and workshops are needed to alert scientists, physicians, and the public to the potential medical benefits of this drug.

Three cases in which the signs and symptoms of Chiari I malformation were induced and worsened after the occurrence of supratentorial mass lesions are reported. The symptoms improved markedly after removal of the supratentorial lesions in these cases. In the first case, a meningioma in the right parietal region coexisted with Chiari I malformation. Although the cerebellar ataxia and nystagmus disappeared after tumor removal, decompressive surgery for the malformation was performed because of upper cervical nerve symptoms and the patient recovered completely. In the second case, the symptoms first occurred after a car accident, and a computed tomographic scan revealed not only a subdural hematoma, but also tonsillar herniation due to Chiari I malformation. After evacuation of the hematoma and decompressive surgery on the craniospinal junction, the symptoms disappeared. In the third case, the symptoms of malformation developed gradually with depression and gait disturbance. A meningioma in the left frontal region coexisted with Chiari I malformation. Although the symptoms improved remarkably after tumor removal, decompressive surgery on the craniospinal junction was performed because of upper cervical nerve symptoms, and the patient recovered completely. These clinical findings indicate that a supratentorial mass lesion may provoke the symptoms of Chiari I malformation in the aged.

A 73-year-old man committed suicide by placing a plastic bag over his head. At autopsy, a large meningioma of the frontal lobe of the brain was found. It is believed that the tumor contributed to death by its direct effect on the brain, causing depression. This article illustrates a relationship between disease, depression, and suicide and offers a brief review of the literature concerning this relationship.

A neurological outpatient department studied 323 consecutive referrals for suspected dementia: 135 (41.8%) were not demented. Of the patients 12.1% had diffuse cognitive disorder; 10.2% circumscribed memory disorder; 0.9% other circumscribed cognitive disorder, 14.2% psychiatric disorder, and 4.3% were judged to be normal. Of the nondemented, 44.1% had a potentially treatable cause for their cognitive symptoms; in 27.4% it was depression. The total of demented patients was 188 (58.2%): 38.8% had primary degenerative dementia; 37.2% vascular dementia including combined degenerative and vascular dementia; and 23.4% had a specific cause. Patients with specific cause were significantly younger than those with other causes of dementia. A potentially treatable cause was found in 10.7% of all demented patients, the most common being metabolic disorders, meningioma, hydrocephalus, subdural haematoma, and depressive pseudodementia.

Dementias which are either reversible or avoidable are discussed in the light of the literature. The frequency is between 6 and 32%. The most important etiological groups are immunological vasculopathies, hyperlipidemia, some types of encephalitis and, mainly, progressive dementia of the insane, benign tumors and in particular meningioma, low pressure hydrocephalus, intoxications due to drugs, industrial products and alcohol, metabolic disturbances, encephalopathy in dialysed patients, ileo-jejunal-bypass encephalopathy and encephalopathy due to neoplasms. Dementias are also seen in endocrinological disturbances and particularly in hypothyroidism. Vitamin B12 and folate deficiency, as well as epilepsy, may be causes of dementia. Depression may mimic a state of dementia. Some features of reversible dementias are listed, including in particular the somewhat more rapid onset, the younger age of patients, and accompanying neurological symptoms such as headache, gait disturbances, ataxia, polyneuropathy, myoclonus or epileptic fits.

Cell-mediated immunity was evaluated in 28 patients with malignant glioma, using in vivo and in vitro tests of lymphocyte function. The results were compared to those found in patients with carcinomatosis (11 subjects), benign brain tumours (9), other neurological disorders (20) and normal, healthy controls (21). Significant impairments of delayed hypersensitivity responses to common antigens was found in patients with malignant glioma and in those with generalised malignancy. A less significant depression of lymphocyte responses was also detected in patients with meningioma. The impairment in cell-mediated immunity was shown not be due to a serum blocking factor. Our data indicate that there is defective T cell function in patients with glioma, similar to that reported in cases with malignancies outside the central nervous system. This impaired immunity may have clinical significance.

The aims of this prospective study were to investigate levels of anxiety and depression in patients with a solitary intracranial neoplasm before and after surgery, and to determine if relationships exist between high levels of anxiety or depression and the hemispheric location of the tumour, the tumour type or patient gender. Patients aged between 17 and 79 years with a solitary intracranial neoplasm completed the Hospital Anxiety and Depression Scale (HAD) before and after biopsy or resective tumour surgery. A control group of non-brain-damaged subjects also completed the HAD before and after lumbar spinal surgery. Of the 109 patients with a brain tumour 30 and 16% demonstrated the likely presence of anxiety and depression, respectively, according to HAD scoring criteria. A greater proportion of females with a left hemisphere tumour reported higher levels of emotional disturbance than any other group of patients; relationships between dysphasia and levels of anxiety or depression were not significant. Patients with a meningioma had higher levels of anxiety and depression as measured by the HAD than those with any other tumour types. Levels of both anxiety and depression were significantly lower after tumour surgery according to the HAD. There were no significant differences in HAD scores between (a) left and right hemispheric tumour groups, and (b) the tumour and control (n = 20) groups. This study has found that anxiety and depression as measured by the HAD are relatively uncommon in patients with an intracranial neoplasm, and that levels of mood disturbance do not differ significantly from those in patients undergoing lumbar spinal surgery. Levels of anxiety and depression become lower after surgery in patients with a brain tumour. Patterns of anxiety and depression in patients with a brain tumour appear to differ from those reported in stroke.

The frequency of mood disorder was studied in a cohort of patients with treated intracranial glioma or meningioma, where psychological morbidity was related to physical and neuropsychological functioning and to the patients' knowledge of their disease. Forty patients were assessed on a range of physical, psychological and neuropsychological measures, with additional interview of a relative to obtain supplementary information regarding each patients' knowledge of their disease. Two (5%) of the 40 patients had clinically significant levels of anxiety, six (15%) clinically significant levels of depression and 92% full or intermediate knowledge about their prognosis. Psychological morbidity was associated with high levels of physical disability and also with cognitive dysfunction, but was not related to the grade of the patient's tumour or the extent to which the patient was aware of the nature of his or her disease. A proportion of patients with intracranial tumours suffer levels of psychological distress sufficient to warrant psychological and/or pharmacological intervention.
