INTRODUCTION Tethered spinal cord is defined as a condition in which the conus medullaris ends at a level below the L1-2 intervertebral space. The spinal cord is considered to be tethered when there is a thick filum terminale or low-lying conus medullaris. It has also been reported that a normal level of the conus medullaris and normal thickness of the(More)
We retrospectively reviewed 77 patients with a tethered spinal cord syndrome to evaluate the results of neurosurgical treatment. The patients were divided into two groups: in group 1 there were 17 patients with primary tethered cord who had normal level conus medullaris (NLCM) and normal thickness filum terminale (NTFT) with urinary incontinence, and group(More)
The paralysis associated with lumbosacral meningomyelocele has been attributed both to myelodysplasia and to degeneration of the exposed neural tissue. Surgically created dysraphism shows that exposure of an intact spinal cord in a genetically normal animal results in degeneration of the normal nervous tissue and subsequent paralysis. Our objective was to(More)
Connective tissue defects may play a significant role in the development of intracranial aneurysms (IAs). Multiorgan connective tissue disorders may, therefore, indicate a risk of IA development. We investigated biomarkers of connective tissue disease in patients with IAs. A series of 62 patients with IAs was studied by physical examination,(More)
OBJECT This paper reports four tethered cord cases who initially applied with lumbar disk disease symptoms. MATERIALS AND METHODS All of them were investigated by magnetic resonance imaging (MRI) and somatosensory evoked potential (SSPE). In two patients, MRI revealed thick and fatty filum terminale, while in remaining two, the filum terminale appeared as(More)
OBJECTIVE Our objective was to investigate the relation between the embryological development and neural tissue maturation at the site where the neural plate failed to form a neural tube. MATERIAL AND METHODS Samples from 15 aborted human fetuses with neural tube defects (NTD). All of the fetuses were between 20 and 25 gestational weeks old. Indicators of(More)
A case of meningioma without dural attachment within the fourth ventricle associated with Sturge-Weber disease is reported. Review of the literature revealed that meningiomas arising from the choroid plexus of the fourth ventricle and lying totally within the fourth ventricle are very rare. Coexistence of Sturge-Weber disease with meningioma of the fourth(More)
OBJECTIVES To investigate acute changes of systemic parameters following experimental subarachnoid hemorrhage (SAH) and cerebral vasospasm conditions created by intracisternal injection of fresh autologous blood in a rabbit model. METHODS The study was carried out at the Neurosurgery Clinic, Izmir Training and Research Hospital, Izmir, Turkey between(More)
A child (8 years old) with a gigantic mass of intracranial hydatid cysts (95x90x75 mm) is presented. The first manifestation was difficulty in walking, which was followed by symptoms of raised intracranial pressure. A craniotomy was performed, and more than 25 hydatid cysts were removed. The literature is reviewed and the incidence of gigantic mass of(More)
In this paper, two cases with mature teratoma of the lateral ventricle are presented. Teratomas are rare intracranial tumours and the most common location is in the midline pineal region. Lateral ventricle as the site of location is very rare. Between the years 1975 and 1996, 120 cases were operated on for lateral ventricle tumours at the University of(More)
