[Acute spontaneous subdural haematoma of arterial origin].

INTRODUCTION: An acute subdural hematoma is often regarded as a complication of head trauma. Occasionally subdural bleeding from the rupture of a cerebral aneurysm or an arteriovenous malformations is described. Spontaneous subdural hematoma is, however, very rare and it commonly has an arterial origin and their aetiology is still a matter of controversy. OBJECTIVE: The purpose of this paper is to present eight cases of spontaneous subdural hematoma seen at our department during the last 19 years. The etiological possibilities of spontaneous subdural hematoma are discussed. PATIENTS AND METHODS: We analyzed 8 cases of acute spontaneous subdural hematoma among a total number of 321 patients with subdural hematoma is presented. RESULTS: There were six males and 2 females with a mean age of 52 years (range 20-66). All patients developed progressive neurological deficits, until become comatose. All eight patients were operated on and surgical mortality was 25%. CONCLUSIONS: Spontaneous subdural hematoma is a rare condition and the prognosis is mainly dependent on the pre-operative neurological state regardless of its origin or cause.

[De novo arachnoid cyst treated with a cystoperitoneal shunt].

INTRODUCTION: Arachnoid cysts (AC) are benign pathological structures that are typically found during childhood, and represent approximately 1% of all intracranial lesions. Unlike cases of secondary cysts with a known causation, which can be attributed to inflammatory processes or traumatic brain injuries, the causation of the primary cysts is unknown. In the cases reported to date, the cysts present from the first imaging study conducted, which is why they are considered to be of a prenatal origin. CASE REPORT: A boy who, at the age of 5 months, is found to have an AC of considerable dimensions that did not appear in a transfontanellar echographic study carried out for other reasons at the age of 2 months. CONCLUSION: The importance of this case lies in the fact that it has been possible to show the appearance of a cyst after birth in a sequence of images in the case of a pathology which, according to all the theories and tests, is considered to have a congenital causation.

[Multiple intracranial meningiomas].

AIMS: Multiple meningiomas is a condition in which the patient had more than one meningioma in several intracranial locations in the same patient without signs of neurofibromatosis. The incidence of multiple intracranial meningiomas varies from 1 to 10% in different series. In this article we report our experience with the diagnosis and treatment of multiple meningioma. PATIENTS AND METHODS: The authors report 13 cases of multiple intracranial meningioma, consecutively operated on at our hospital between 1983-2003. All the patients were studied with CT and the last 10 with MRI. In 8 patients all of the tumours were found at the first admission. In the other five the diagnosis was not established until years after removal of the first meningioma. All the patients showed no manifestations of von Recklinghausen disease. RESULTS: The overall average age at diagnosis was 53.3 years: 7 were females and 6 males. The predominant site for the meningioma was the parasagittal and falcine region, followed by the cerebral convexity. Thirty-two meningiomas were treated with surgical extirpation and in four cases the treatment was radiotherapy. CONCLUSIONS: Multiple meningiomas are not a specific disease entity and have no distinctive clinical, pathological or surgical features. Despite the multiplicity of sites, multiple meningiomas do not differ in prognosis from benign solitary meningiomas.

[Atypical and malignant intracranial meningiomas].

INTRODUCTION: Meningiomas are one of the most common tumours of the central nervous system, with an incidence of 15% to 20% of all primary brain tumours. Meningiomas are generally slowly growing, benign tumours attached to the dura-mater and composed of neoplastic meningothelial cells. Most of meningiomas are benign and can be graded into WHO grade I. However certain histological subtypes are associated with a poor clinical outcome and correspond to WHO grades II and III. OBJECTIVE: To review the epidemiology, clinical, surgical, and histological aspects of multiple intracranial meningiomas. PATIENTS AND METHODS: The authors report 12 cases of malignant intracranial meningioma, consecutively operated on at our hospital between 1985-2002. All the patients were studied with CT and the last 9 with MRI. All patients showed no manifestations of von Recklinghausen disease. RESULTS: The age at diagnosis ranged from 39 to 87 (mean 64.3 years). There were 6 males and 6 females. The predominant site for the meningioma was the parasagittal region (5 cases), followed by the cerebral convexity (3 cases). All meningiomas were treated with surgical extirpation and in 8 cases the treatment was radiotherapy. The more common histological subtype was atypical meningiomas (5 cases). The median time survival was 48 months (range 16-168). CONCLUSIONS: Malignant meningiomas constitute 1% to 10% of all meningiomas. They affect men and women almost equally, in contrast, benign meningiomas are more commonly found in women. Complete surgical resection and administration of adjuvant irradiation following initial resection is crucial to long term control.
