Giant Invasive Intradural Extramedullary Lumbar Schwannoma: A Case Report and Literature Review.

Schwannomas are benign nerve sheath tumors that arise from Schwann cells, which are responsible for producing the myelin sheath that surrounds nerves. They are typically slow-growing and can occur in various locations in the body, including the lumbar region of the spine. We present a case of giant invasive intradural extramedullary schwannoma managed with posterior lumbar interbody fusion (PLIF) and laminectomy with excellent results.

Development of a 3D Printed Brain Model with Vasculature for Neurosurgical Procedure Visualisation and Training.

Background: Simulation-based techniques using three-dimensional models are gaining popularity in neurosurgical training. Most pre-existing models are expensive, so we felt a need to develop a real-life model using 3D printing technology to train in endoscopic third ventriculostomy.

Methods: The brain model was made using a 3D-printed resin mold from patient-specific MRI data.

Thoracic Percutaneous Vertebroplasty for the Treatment of Vertebral Hemangioma in a Patient With Forestier's Disease: A Case Report.

Percutaneous vertebroplasty consists of an injection of polymethylmethacrylate in the vertebral body, with the aim of reinforcing the bone structure, preventing vertebral collapse, and achieving analgesic and antitumor effects. It is used in the treatment of patients with aggressive vertebral hemangiomas, as well as compression fractures of traumatic etiology and pathological fractures. Forestier's disease is also known as senile ankylosing hyperostosis of the spine.

Degenerative Grade 3 Spondylolisthesis Management: A Case Report and Literature Review.

Degenerative spine disorders are very common in the aging population. Degenerative spondylolisthesis is a relatively uncommon cause of chronic back pain in these patients. We present a case of high-grade spondylolisthesis managed with posterior lumbar interbody fusion (PLIF) and reduction of the listhesis with excellent results.

Three-Dimensional Plastic Modeling on Bone Frames for Cost-Effective Neuroanatomy Teaching.

Cadaveric models remain an essential part of medical training across all specialties. Due to their scarcity, high costs, and possible health hazards, there is a need for more accessible and affordable alternatives, especially in low-resource settings. We introduce cost-effective and easily replicable three-dimensional (3D) printed models to help democratize access to hands-on neuroanatomy education.

Surgical Management of Lumbar Hardware Failure Due to Recurrent Postoperative Spondylodiscitis: Case Report.

Spondylodiscitis is a rare bacterial infection of the vertebrae and intervertebral discs that causes inflammation and follows a destructive course. When conservative management fails, surgical management requires immediate debridement of the infective focus, with decompression and stabilization through a ventral approach. The most frequently involved locations are the lumbar spine (58%), thoracic (30%), and cervical (11%) regions.

Microsurgical Wiltse Paraspinal Approach Using a Low-Budget Exoscope.

Access to microneurosurgical care in low- and middle-income countries remains limited mainly due to a lack of equipment. High purchasing and maintenance costs hinder the use of operating microscopes in low-resource facilities. The authors present an improved version of their previously introduced low-cost exoscope to achieve high magnification and illumination in low-resource environments.

Basal cisternostomy for traumatic brain injury: A case report of unexpected good recovery.

In subarachnoid hemorrhage following traumatic brain injury (TBI), the high intracisternal pressure drives the cerebrospinal fluid into the brain parenchyma, causing cerebral edema. Basal cisternostomy involves opening the basal cisterns to atmospheric pressure and draining cerebrospinal fluid in an attempt to reverse the edema. We describe a case of basal cisternostomy combined with decompressive craniectomy.
