Managing such lesions remains an arguable neurosurgical challenge. The study aimed to discuss the management of MPEs by evaluating the long-term surgical outcomes of consecutively treated MPEs in different 3 neurosurgical centers.

Surgical Outcome of Spinal Subdural Abscesses: A Report of Four Consecutive Patients and Brief Review of the Literature.

Background And Study Aims:  Spinal subdural abscesses (SSAs) are rare and have a poor prognosis, especially when they are diagnosed late. In the literature, most cases of SSAs have been reported as case reports and small case series. In this study, we aimed to evaluate the surgical outcomes of four consecutive SSA patients.

Long-term surgical outcome of Chiari type-I malformation-related syringomyelia: an experience of tertiary referral hospital.

Objective: Syringomyelia is a common condition seen in patients with Chiari type-I malformation (CM1). The purpose of this retrospective study was to evaluate the long-term clinical and radiological outcomes of posterior fossa decompression with duraplasty (PFDD) with coagulation of tonsillar ectopia in consecutive surgically treated adult patients with CM1-related syringomyelia (CRS).

Methods: Over 9 years' duration (1993-2001), medical charts of diagnosed patient with CM1 at our neurosurgical center were reviewed retrospectively.

Clinical and radiological evaluation of treated Chiari I adult patients: retrospective study from two neurosurgical centers.

Chiari malformation type I (CM1) is a common neurosurgical disorder. It often causes debilitation in the affected patients. CM1 is a herniation of the caudal cerebellum into the spinal canal.

Radiologic-Histopathologic Correlation of Adult Spinal Tumors: A Retrospective Study.

Aim: Preoperatively performed magnetic resonance images (MRIs) are essential before treating spinal tumors surgically. This study aims to investigate the compatibility of MRI preliminary diagnosis and proven histopathologic diagnosis of consecutively operated 96 spinal tumors.

Material And Methods: Medical records were retrospectively reviewed for all spinal tumors operated at our institute during a period of 6 years.

Pediatric Spinal Ependymomas.

BACKGROUND The aim of this study was to assess the clinical and radiological outcomes of surgical treatment for primary spinal ependymoma in children. MATERIAL AND METHODS Medical records of 46 primary spinal ependymoma patients who underwent surgery in BRSHH hospital during a 12-year period from 2004 to 2015 were retrospectively reviewed. All pediatric patients (patient age <18 years) were selected as the core sample used for this study.

Primary Ewing Sarcoma of Frontotemporal Bone in Geriatric Patient.

Background: Ewing sarcoma is a rare primary malignant bone tumor, which mainly affects children and adolescents. Calvarial bone involvement and its appearance in elderly patients are extremely rare.

Case Description: We presented a 68-year-old female patient with headache and right frontotemporal swelling.

Clinical outcomes of multiple aneurysms microsurgical clipping: Evaluation of 90 patients.

Background: The incidence of multiple intracranial aneurysms (MIAs) among patients who are diagnosed with aneurysm is 15-45% in the literature. Treatment options depend on the patient's status, age, aneurysm location and neurosurgeon's experience. In this study outcomes of micro-surgically clipped 90 patients have been evaluated.

Anterior cervical fusion with interbody cage containing beta-tricalcium phosphate: Clinical and radiological results.

Aim: Beta tricalcium phosphate (beta-TCP) is an osteoconductive, resorbable material. Its clinical effectiveness has been proved in many indications. This study was clinical and radiographic study report obtained in patients undergoing anterior cervical discectomy and fusion ACDF in which PEEK cages were filled beta-TCP in an injectable form.

Primary Intracranial Germinomas: Retrospective Analysis of Five Cases.

Aim: Primary intracranial germinomas (PIGs) are rare malignant brain tumors that represent approximately 0.2% to 1.7% of all primary intracranial tumors.

Long-term Surgical Outcomes of Spinal Schwannomas: Retrospective Analysis of 49 Consecutive Cases.

Aim: Spinal schwannomas (SS) represent the most common intradural extramedullary lesions, accounting for approximately 24% of all nerve sheath tumors in adults. Schwannomas have infrequent, but existent possibility of malignancy. In this study, long-term outcomes of 49 consecutive SS have been presented.

Management of Tethered Cord Syndrome in Adults: Experience of 23 Cases.

Aim: Tethered cord syndrome (TCS) is rarely diagnosed in adults. It is a complex clinicopathological entity that remains poorly understood. In this study, clinical outcomes of 23 consecutive congenital TCSs diagnosed in adults have been evaluated to establish a standard approach to treat congenital TCS diagnosed in adults.

Measuring serum matrix metalloproteinase-9 levels in peripheral blood after subarachnoid hemorrhage to predict cerebral vasospasm.

Purpose: We aimed to investigate serum levels of matrix metalloproteinase-9 in both subarachnoid hemorrhage and control groups for prediction of cerebral vasospasm in this study.

Methods: Venous serum matrix metalloproteinase-9 levels were prospectively measured four times (days 1, 3, 7, and 14) for 34 consecutive patients with subarachnoidal hemorrhage (n = 27) and for elective aneurysm clipping (control, n = 7).

Results: Vasospasm developed in 11/34 (32.

Solitary osteochondroma arising from cervical spina bifida occulta.

Solitary osteochondromas are common benign long bone tumors originating from cartilage. They may produce a wide variety of symptoms and complications depending on their spinal location. These may include compressive myelopathy, nerve root compression, pathologic fracture and malignant degeneration, or in some cases only pain.
