Unilateral Blindness After Posterior Cervical Spinal Surgery: A Case Report
The purpose of this study is to report the case of a patient who developed an unusual combination of central retinal artery occlusion with ophthalmoplegia after spinal surgery. A 69-year-old man underwent a cervical spinal fusion surgery in the prone position. He could not open his right eye in the recovery room due to ocular swelling. Upon ophthalmological examination, we determined that he had a central retinal artery occlusion with total ophthalmoplegia. Despite medical treatment, optic atrophy was present at the follow-up examinations. Ptosis and the afferent pupillary defect disappeared, and ocular motility was recove...

Traumatic Lumbosacral Root Avulsion Mimicking Epidural Hematoma: A Case Report
In this report, we describe a case of a traumatic lumbosacral nerve root avulsion without bony spinal injury mimicking epidural hematoma. Because of the difficulty of evaluation at the initial stages of injury, surgeons need to be able to differentiate between root avulsion injury and epidural hematoma, because both cerebral spinal fluid and hematoma can be present in the injury area.

Skull Base Chondroma: A Case Report and Review of Literatures
We report a case of a 60-year-old woman who had an 8-year-old history of nonsignificant incentive dizziness and headache and a 3-month-old history of paroxysmal numbness on the left face and in the right toe. Magnetic resonance imaging of the head revealed a nonenhanced tumor occupying the left side of cavernous sinus. A cerebrovascular digital subtraction angiography revealed that the tumor was wrapped and supplied with blood by a bulky abnormal vessel branching out from the posterior cerebral artery; the pathologic diagnosis was chondroma. At present, the most effective treatment is to resect the tumor as completely as p...

Idiopathic Lumbosacral Plexopathy Mimicking Nerve Sheath Tumor
The lumbosacral plexus is composed of ventral primary rami of the lumbar and sacral roots and supplies the lower extremity. Idiopathic lumbosacral plexopathy is a rare clinical entity. The underlying etiology and pathology is not clearly known. Clinical findings are asymmetrical leg pain and sensory symptoms followed by weakness and atrophy in the subsequent weeks or months. Electrophysiologic investigation and magnetic resonance imaging provide valuable information in the diagnostic work-up. A thorough understanding of the anatomy and a comprehensive differential diagnostic approach is crucial in the evaluation lumbosacra...

Morphometric Analysis of the Influence of Zinc on the Vasospastic Femoral Artery in Rats
Aim: Cerebral vasospasm is one of the most prominent causes of morbidity and mortality after subarachnoid hemorrhage. It is well known that free radicals and lipid peroxidation exist among the theories of vasoconstriction in the etiopathogenesis of cerebral vasospasm. Zinc is responsible for the activity of superoxide dismutase enzyme and may prevent or minimize the vasoconstriction that is caused by free oxygen radicals. Many studies have been conducted with antioxidant agents, but we have not found any investigation for the prevention of cerebral vasospasm with zinc by increasing the enzyme activity. Materials and Method...

Surgical Treatment of Symptomatic Chiari I Malformation: A Consecutive Case Series From a Developing Country
Conclusions: CM I should be considered in the list of differentials in patients with nonspecific headaches and neck pains. Timely surgical intervention for symptomatic CM I patients can lead to significant clinical improvement. However, the extent of decompression, the need for duraplasty, and the choice of graft material lack general consensus. In CM I patients with associated scoliosis and syringomyelia, decompressive surgery may halt further progression of the spinal abnormalities. (Source: Neurosurgery Quarterly)

New Methods of Subdural Hematoma Volume Estimates
Subdural hematoma is one of the common intracranial hematomas. Hematoma morphology presents a crescent shape. Most usually, the Dorian formula is used to estimate the volume, but the error is large. The aim of this paper was to better measure the volume of spherical segment to derive on improved formula for calculating the subdural hematoma volume. It uses hematoma volume measured by a computer software as a more accurate standard. We make the calculation values of the hematoma volume to compare with Dorian formula separately. Finally, studying a new method, which is more simple and accurate for subdural hematoma volume es...

Endoscopic Removal of Third Ventricular Colloid Cyst: Experience of 90 Cases
Conclusions: Being a burr hole technique, endoscopy offers a real safe and effective minimally invasive tool for treating third ventricular colloids. It offers superior illumination, greater magnification, and enhanced visualizations of the ventricular anatomy. There is no doubt that the mortality, morbidity, and operative costs are less with endoscopy when compared with other combating therapeutic modalities. In our opinion, if the endless argument considering the point of tumor recurrence is brought apart, endoscopy should be the first-line treatment for third ventricular colloid cysts.

Pedicle Screw Fixation at the Level of the Fracture: The Postoperative Kyphosis Rate and Replacement of the Fractured Body
The tendency to use internal fixation with surgery to remove penetrating fragments in the spinal canal even in the absence of neurological deficits has increased. All 3 methods of posterior, anterior, and combination fixations are used, and yet the optimal management of thoracolumbar fractures is controversial. There is a lack of comprehensive review comparing the 2 methods of embedded systems in fractured vertebrae (segmented) and nonembedded pedicular screws in fractured vertebrae (nonsegmented). Twenty adult patients with vertebral fracture were evaluated in this randomized clinical trial. Patients underwent radiologic ...
