Systematic Analysis of Publication Bias in Neurosurgery Meta-Analyses.

Background: Statistically significant positive results are more likely to be published than negative or insignificant outcomes. This phenomenon, also termed publication bias, can skew the interpretation of meta-analyses. The widespread presence of publication bias in the biomedical literature has led to the development of various statistical approaches, such as the visual inspection of funnel plots, Begg test, and Egger test, to assess and account for it.

Trigonal cavernous angiomas: report of three cases and review of literature.

Background: Intraventricular cavernous angiomas are very rare. Only few cases of trigonal angiomas have been reported.

Case Description: We report three cases of trigonal cavernous angiomas who presented with raised intracranial pressure or seizures and who underwent total excision with a good recovery.

Chronic subdural haematoma associated with nontraumatic CSF rhinorrhea: a management challenge.

We report an unusual case of chronic subdural haematoma (CSH) associated with cerebrospinal fluid (CSF) rhinorrhoea emphasizing the importance of managing both conditions simultaneously. A 59- year-old man presented with watery discharge from the right nostril, of 2 months duration. MRI of the brain showed a CSH in the left fronto-parietal region with significant mass effect.

Necrobiotic xanthogranuloma with cutaneous and cerebral manifestations. Case report and review of the literature.

Necrobiotic xanthogranuloma (NXG) is a rare inflammatory histiocytic disease of the skin. Xanthogranuloma of the central nervous system is rare and few cases have been reported. To the authors' knowledge, there has been no previously reported case of NXG in which an intracranial lesion was found.

Rate of resolution of histologically verified intracranial tuberculomas.

Objective: The goal of this study was to determine the rate of radiological resolution of histopathologically proven tuberculomas treated with antituberculous therapy (ATT). The effects of the size of the tuberculomas, the number of tuberculomas, and the addition of corticosteroid therapy on the rate of resolution of the tuberculomas were also studied.

Methods: Twenty-eight patients (age range, 5-48 yr; 14 male and 14 female patients) with histologically proven intracranial tuberculomas were prospectively monitored with contrast-enhanced computed tomographic scans.
