Brain stem epidermoid cysts are extremely rare lesions. Only nine cases have been reported. Management of the epidermoid cyst is decompression of cyst contents and removal of cyst capsule. But in some cases resection of the cyst may result in a poor outcome because of cyst wall adhesion into the brain stem.
A rare case of meningioma of the fourth ventricle is reported. A review of the literature revealed only 24 reported cases of this type of tumor.
Experience is the important point in reduction of the complications and in the effectiveness of the surgical procedure in pituitary surgery. Endoscopic pituitary surgery differs from microscopic surgery, since it requires a steep learning curve for endoscopic skills. In this article, we evaluate our learning curve in two groups, as early and late… (More)
We have evaluated the influence of fluorescein-guided resection on gross total resection (GTR) and survival in a series of patients with GBM. Group 1 consisted of 47 patients given fluorescein and group 2 comprised 33 patients, on whom fluorescein was not used. Median survival time was 43.9 weeks in the patients given fluorescein and was 41.8 weeks in the… (More)
The endoscopic transsphenoidal approach has been reported in the literature as a useful tool to treat sellar and parasellar lesions. The endoscope permits a panoramic view instead of the narrow microscopic view, and it allows the inspection and removal of the lesions of sellar, parasellar, and suprasellar compartments by angled-lens endoscopes. On the basis… (More)
Current literature reveals different opinions about the effectiveness of endoscopic third ventriculostomy in the treatment of hydrocephalus in children less than 2 years of age. Performing a retrospective evaluation of our own experience in this age group, we aimed to contribute to the growing data on the controversial issues related to this procedure in… (More)
Aneurysm of an azygos anterior cerebral artery is rare. Two cases are presented. In case 2, the coexistence of arachnoid cyst with this aneurysm is reported. Literature is reviewed.
INTRODUCTION The management of epidural hematoma is classified into surgical or conservative treatment according to clinical and radiologic parameters. In the recent years, the number of paper suggesting conservative management has been increasing. The experimental works that have been performed are based on especially the effects of epidural hematomas.… (More)
OBJECT In this report, the authors describe their experience with surgical access to the cavernous sinus via a fully transnasal endoscopic approach in 20 cases. Clinical and endocrinological follow-up are discussed. METHODS The authors used an endoscopic transsphenoidal approach in 192 patients with pituitary adenomas between September 1997 and January… (More)
BACKGROUND Visual field analyses reflect the degree of the compression to the optic nerve that results the structural damage of the nerve. These structural damages can be evaluated by diffusion tensor imaging (DTI), which assesses the structural integrity of white matter tracts. Thus, we evaluated the quantitative assessment of early visual recovery in… (More)
