Decompressive surgery or craniectomy (DC) is a treatment option, which should be considered when the intracranial pressure (ICP) cannot be treated by conservative methods. The purpose of this study was to evaluate the benefits of decompressive craniectomy in patients with intractable posttraumatic intracranial hypertension and to evaluate the patient(More)
BACKGROUND Intraventricular hemorrhage and posthemorrhagic hydrocephalus are common causes of neonatal morbidity and mortality among preterm and low-birth weight infants (PT-LBWIs). Clinical management of posthemorrhagic hydrocephalus (PHH) is difficult and not well standardized. In this study, we aimed to determine the incidence of hydrocephalus after(More)
We retrospectively evaluated computed tomography angiography (CTA) and perfusion imaging (CTP) of patients with aneurysmal subarachnoid hemorrhage (SAH) for any correlation between degree of vasospasm and perfusion deficit. Sequentially performed CTP and CTA of 41 patients at least at the third day of postbleeding were reviewed for vasospasm and perfusion(More)
AIM Debate continues as to whether decompressive craniectomy (DC) is an effective treatment for severe traumatic brain injury (STBI). DC is mostly used as a second tier treatment option. The aim of this study was determined whether early bilateral DC is effective as a first tier treatment option in patients with STBI. MATERIAL AND METHODS The study(More)
Background. The incidence of chronic hydrocephalus requiring shunt placement is a well-known and common complication of aneurysmal subarachnoid hemorrhage (aSAH). It was suggested that fenestration of the lamina terminalis (LT) during microsurgery for aSAH may be associated with a reduced rate of shunt-dependent chronic hydrocephalus (SDCH). We analyzed(More)
BACKGROUND This study aimed to compare serum and cerebrospinal fluid (CSF) S-100b protein levels after a severe head injury. The changes in serum S-100b and CSF S-100b concentrations were investigated as indicators of brain damage for patients suffering from severe head injuries. METHODS The sample included 48 patients with Glasgow Coma Scale scores of 8(More)
Intradural spinal lipomas of thoracic cord are quite rare. It is known that lipomas are hamartomas, which change their size with alterations of body fat. An 18-year-old male patient, with a thoracic intradural lipoma showing spontaneous decrease in the size of a residual lipoma and tethering of the cord 4 years after surgery, is presented in this report.
OBJECTIVE AND IMPORTANCE A rare case of bilateral cerebellopontine angle (CPA) arachnoid cysts (ACs), accompanied by cerebellar tonsillar displacement toward the foramen magnum, is presented. CLINICAL PRESENTATION A 45-year-old woman presented with progressive dysphagia, vertigo, and truncal ataxia. Magnetic resonance imaging revealed bilateral CPA ACs(More)
Central neurocytoma is a rare neuroectodermal tumor generally found in young adults. It mainly originates from lateral ventricles. Extraventricular location of this kind of tumor, especially spinal cord involvement, is extremely rare. This article is the ninth case of central neurocytoma derived from the spinal region, and includes a review of the(More)
