Analysis of the Cranial Aperture of the Optic Canal in Patients with Chiari Type-I Malformation.

Aim: To examine the morphological properties of the cranial aperture of the optic canal (CAOC) in patients with a Chiari type-I malformation (CIM).

Material And Methods: Radiological images of 40 patients with CIM (24 females/16 males, mean age: 20.75 ± 14.

Assessment of the Anterior Clinoid Process and Optic Strut in Chiari Malformation Type I: A Computed Tomography Study.

 This study aimed to evaluate morphological features of the anterior clinoid process (ACP) and the optic strut (OS) in Chiari malformation Type I (CM-I).  The study universe consisted of computed tomography images of 41 CM-I patients and 45 normal subjects. Comparison of the parameters for CM-I and the control group was performed with the Student's -test.

Analysis of the Prechiasmatic Sulcus in Chiari Malformation Type I.

Objective: To assess morphologic features of the prechiasmatic sulcus (PS) in Chiari malformation type I (CM-I).

Methods: Computed tomography images were obtained in patients with CM-1 (mean age: 21.26 ± 16.

Structure of corona radiata and tapetum fibers in ventricular surgery.

In this study the three-dimensional anatomy of the corona radiata and tapetum via the fiber dissection and diffusion tensor imaging of the brain for ventricular surgery was demonstrated. Ten formalin-fixed cerebral hemispheres were dissected for corona radiata and tapetum via Klingler's fiber dissection method under an operating microscope. The corona radiata and tapetum were dissected through lateral and medial surfaces of the cerebral hemisphere, respectively.

The Effect of Levetiracetam on Closure of the Midline in Early Chicken Embryos.

Aim: Genetic predisposition and some environmental factors play an important role in the development of neural tube defects. Levetiracetam is a new drug that has been approved in the treatment of partial seizures. We aimed in this study to determine the effect of levetiracetam on chick embryos.

Fragmentation to epidural space: first documented complication of Gelstix(TM.).

The knowledge of minimal invasive spinal surgery has increased greatly in recent years. A current issue is the hydrogel implant inserted through nucleus pulposus. In this paper we present a case in which the hydrogel implant was found to be fragmented into the spinal canal at follow up.

High dose cotinine may induce neural tube defects in a chick embryo model.

Aim: Nicotine is a well-known agent among 4000 chemicals in cigarettes. About 70 to 80% of nicotine is converted to cotinine, a major metabolite. The aim of the present study is to investigate the effect of cotinine on neural tube development in a chick embryo model.

MR imaging of multiple sclerosis simulating brain tumor.

Multiple sclerosis (MS) may sometimes present as a mass lesion that is clinically and radiologically indistinguishable from brain tumor. The initial recognition of such cases is essential to avoid a surgical intervention and supplementary treatment. Sometimes areas adjacent to a tumor may present similar histopathological features with non-neoplastic demyelinating lesions.
