Retroclival epidural hematoma: A rare location of epidural hematoma, case report, and review of literature.

Retroclival epidural hematoma in adults is uncommon. Although most cases are associated with craniocervical trauma, other mechanisms have been reported, such as coagulopathy, vascular lesions, and pituitary apoplexy. We report two adults diagnosed with retroclival epidural hematoma.

Spinal Hydatid Cyst Disease : Challenging Surgery - an Institutional Experience.

Objective: Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2-1%.

Is a Unilateral Surgical Approach Effective in Patients with Bilateral Leg Pain with Unilateral Lumbar Disc Herniation? A Prospective Nonrandomized Clinical and Surgical Study.

Objective: To examine the surgical results of unilateral lumbar discectomy in patients with bilateral leg pain and discuss short- and long-term outcomes within the limits of lumbar decompression.

Methods: We analyzed 60 patients with unilateral disc herniation who underwent unilateral lumbar discectomy and hemipartial laminectomy between 2014 and 2017. Group 1 (30 patients) had bilateral leg pain and unilateral lumbar disc herniation.

Preoperative Exposure of Sigmoid Sinus Trajectory in Posterolateral Cranial Base Approaches Using a New Landmark Through a Neurosurgical Perspective.

The location of burr holes in posterolateral cranial base approaches should be appropriate to provide an adequate operative field, and surgical freedom is crucial for bone window opening. The aim of this study was to search for more convenient and easily detectable landmarks in comparison with current landmarks in posterolateral cranial base surgery. Twenty 3-dimensional reconstructed head and neck computed tomography angiography images (group 1) and 20 cadaver heads (group 2) were evaluated.

Visualization of Superficial Cerebral Lesions Using a Smartphone Application.

Aim: Accurate localizations of cerebral lesions ensure good surgical outcomes and minimize intraoperative complications. Currently, microscope-integrated neuronavigation systems compensate these requirements. Since these units are expensive and large, the need to create more practical and portable systems in this "smart" century has become apparent.
