Hirnabsze� durch fehlerhafte Crutchfield-Zange
1973
Mitteilung uber einen Fall von Hirnabszes nach Anwendung der Crutch-field-Zange. Ursache: Fehlende Kropfung am Dorn der Zange, der so den gesamten Schadelknochen und die Dura mater durchdringen konnte. Unerlaslich ist eine ausreichende Kropfung am Ansatzdorn der Zange und die Anlage des Bohrlochs parietal, nicht, wie vielfach durchgefuhrt, in der dunneren Temporalschuppe.
Nocardiose cérébrale et pulmonaire à Nocardia abscessus chez un patient algérien immunocompétent
2018
International audience; Nocardial brain abscess is often occurring in immunocompromised patients. It is uncommon in immunocompetent individuals. Here, the authors describe a case of cerebral and pulmonary nocardiosis mimicking a metastatic tumor in an apparently health 40-year-old Algerian male. The patient presented multiple brain abscess revealed by inaugural epileptic seizure. He was afebrile and presented with left hemiparesis. Staging imaging showed a nodular lung lesion in the apical segment of the right lower lobe. The patient underwent double craniotomy for resection of the lesion. Culture of the resected specimen isolated Nocardia abscessus. The patient was initially started on int…
CT and MR Imaging of Non-neoplastic Intracranial Masses
1989
Many intracranial mass lesions of non-neoplastic origin present CT and MR features similar or identical to those of true neoplasms. In many cases a definitive diagnosis cannot be made from imaging findings alone, and misinterpretation is possible even when the history and clinical findings are considered. Yet an accurate preoperative diagnosis is an essential prerequisite for selecting candidates for a neurosurgical operation and planning the procedure. In some cases the full range of neuroradiologic techniques may have to be applied and evaluated in the context of clinical findings before the physician can accurately classify the disease and draw appropriate therapeutic conclusions.
Isolation of Abiotrophia adiacens from a brain abscess which developed in a patient after neurosurgery.
1999
ABSTRACT We report the case of a patient who developed a large brain abscess after neurosurgery. Cerebrospinal fluid from the abscess drainage yielded Abiotrophia adiacens -specific PCR products and microorganisms that were identified by conventional microbiological methods and by 16S ribosomal DNA analysis as Abiotrophia adiacens , which was formerly classified as a member of nutritionally variant streptococci.
Computed Tomography in Nonneoplastic Space-Occupying Intracranial Lesions
1981
A number of nonneoplastic intracranial space-occupying lesions may resemble neoplasms in the CT scan, and definitive diagnosis is not possible with CT studies alone in many cases. Misinterpretations are possible, even when all clinical data are considered in the interpretation of the CT scan. However, the most accurate possiblepreoperative diagnosis is a prerequisite for decisions on therapeutic strategy and surgical approach. Therefore some cases may require the full range of conventional neuroradiological techniques and careful consideration of clinical findings for correct interpretation of the CT scan with its consequences for therapy. Table 6 summarizes the most common alternatives in …

However, data are lacking on the epidemiology globally. We perfor…
Evolution of brain abscess in cats formation of capsule and resolution of brain edema
1980
Brain abscess evolution was studied in an experimental model in the cat correlating the computed tomographic scan appearance with intracranial pressure, brain edema and histopathological findings. Brain inflammation was produced by direct inoculation of Staphylococcus aureus into the white matter. Abscesses developed in all animals. The ring enhancement around the necrotic focus seen at an early stage after contrast-medium injection cannot be equated with capsule formation as long as the abscess diameter increased. Parallel to the acute stage of abscess, the intraventricular pressure increased due to the rising mass effect and the spreading edma. The morphological investigations revealed on…

Fluency and rule breaking behaviour in the frontal cortex
2020
Design (DF) and phonemic fluency tests (FAS; D-KEFS, 2001) are commonly used to investigate voluntary generation. Despite this, several important issues remain poorly investigated. In a sizeable sample of patients with focal left or right frontal lesion we established that voluntary generation performance cannot be accounted for by fluid intelligence. For DF we found patients performed significantly worse than healthy controls (HC) only on the switch condition. However, no significant difference between left and right frontal patients was found. In contrast, left frontal patients were significantly impaired when compared with HC and right frontal patients on FAS. These lateralization findin…
