    Notes: Abstract 52 patients with non-acoustic neurinoma tumors of the cerebellopontine angle undergoing surgery over a 16 year period (1974–1989) are analyzed with regard to epidemiologic factors, presenting symptoms, neurological findings, diagnostic procedures, surgical approaches, recurrences, and longterm survival rates. Meningiomas (20 cases) and epidermoid tumors (16 cases) outnumber the rare tumors which exhibit wide histological variation. Trigeminal neuralgia was found as a significantly frequent sign of epidermoids. Total removal was possible in nine meningiomas (45%), fourteen epidermoid tumors (87.5%) and 11 (69%) mostly malignant rare tumors. There were many longterm survivors in meningioma and epidermoid groups with a median follow-up period of 4.1 years. The results are compared to those reported in the literature and a brief review of reported rare tumors of the angle is presented.

    Notes: Abstract Symptomatic intracranial hemorrhage (ICH) in term infants is not common, but when it occurs it is usually secondary to trauma, coagulation disorders and/or hypoxia. The possibility of a structural cause for an infantile ICH is unfortunately not seriously considered until very late. In this paper we report the cases of five full-term infants, each of whom developed ICH secondary to a structural lesion during the 1st year of life. Three presented during the newborn period. A congenital saccular aneurysm of the middle cerebral artery in an 8-month old male infant; a posterior fossa arteriovenous malformation in a 2-week old female neonate; a deep parietal cavernous angioma in a 6.5-month-old male infant; a temporoparietal low-grade astrocytoma in a 12-day old male neonate and a temporoparietal desmoplastic ganglioglioma in a 9-day-old male neonate were the structural lesions that were causative for hemorrhage. In all cases but one, the diagnosis was reached by computerized tomography and/or magnetic resonance imaging. All infants underwent surgery for the removal of the hematoma and of the lesion causative for the bleed. All are alive at 19, 3, 11.5, 10, and 5 years, respectively. We discuss the diagnosis of ICH with special emphasis on contemporary imaging modalities and stress the benefits of aggressive and timely surgical treatment. We then consider a concise analysis of the world literature on the occurrence of structural causes of ICH during infancy.

    Has modern management improved the outcome of infants with intracranial tumours? (1990)

    Notes: Abstract Records of 92 children were reviewed who, in the first 18 months of life had an intracranial tumour, and who were registered with the Manchester Children's Tumour Registry during the 34-year period from 1953 to 1987. The incidence of intracranial tumour was 1 in 25000 live births, and 85% of the tumours were malignant. The introduction of computed tomography (CT) in the region in 1976 improved the diagnostic accuracy and led to early diagnosis. This also coincided with refined radiotherapy and improved chemotherapy. The surgical attitude became more aggressive, and with early treatment, mortality was reduced, though the 1-month operative mortality still remains high at 15%. All survivors were available for follow-up. All children with axial tumours died within 9 years. Long-term follow-up did not suggest significant improvement in the overall survival or in the quality of life, though there was a significant improvement in the 5-year survival rate with modern management.

    Notes: Abstract An unusual case of primary extranodal Burkitt's-type lymphoma of the frontal base dura and adjacent bone with intradural invasion is reported in a 5-year-old child who presented with unilateral loss of vision in the left eye. Tissue diagnosis was obtained through a craniotomy and the patient received radiotherapy plus intravenous and intrathecal chemotherapy. The tumor regression and improvement in vision was well documented by means of CT and visual evoked potential studies (VEP). A review of the literature on this exceptionally rare tumor is presented.

    Management of brain abscess in children: review of 130 cases over a period of 21 years (1992)

    Notes: Abstract The data on 130 children with brain abscesses treated over 21 years (1970–1990) were analyzed retrospectively. The whole group included four infants. Chronic ear infection and cyanotic congenital heart disease were the most common predisposing factors. In infants, meningitis and/or ventriculitis were dominant in the etiopathogenesis. Cases were evaluated according to the treatment received and also according to time periods. More than half of the patients (n=74) in this series were treated by primary or secondary excision. Computed tomography (CT) facilitated the diagnosis and helped the planning of treatment. Aspiration gained increasing credit after the advent of CT. Microorganisms could be identified in 54% of the cultured specimens. Staphylococci, streptococci and Proteus were the dominating microorganisms. Penicillin and chloramphenicol have long been the mainstay of antimicrobial therapy but have recently been replaced by third-generation cephalosporins and sulbactam-ampicillin combinations. Overall mortality was 15.5% but showed a decline from 30% in the pre-CT era to 6% in the last 5 years and to zero in the last three. Neither the location nor associated heart disease contributed to the mortality, but mortality among infants was as high as 50%.

    Intracranial plasma cell granuloma (2000)

    Notes: Abstract Plasma cell granulomas (PCGs) are benign, inflammatory masses of unknown etiology composed of polyclonal mature plasma and lymphoid cells. The lung is their most common location, and occurrence within the cranial cavity is extremely rare. We report the case of an 11-year-old girl who presented with seizures and was diagnosed as having a dural-based right frontal tumor that extended toward the sagittal sinus and the falx. The lesion was totally excised, together with the abnormal dura. A limited cortical excision was also performed using electrocorticographic guidance. Histopathologic diagnosis of intracranial plasma cell granuloma was reached after extensive immunohistochemical tests and electron microscopy. This is the third case of PCG with description of changes in the neighboring cerebral tissue. Although PCGs are well-circumscribed lesions, lymphoplasmocytic inflammation, neuronal loss, and reactive gliosis occur within the adjacent cortex. Disturbed cortical lamination, as we have observed, appears to be a histological finding that has not been described previously.
