Isolated leptomeningeal angiomatosis in the sixth decade of life, an adulthood variant of Sturge Weber Syndrome (Type III): role of advanced Magnetic Resonance Imaging and Digital Subtraction Angiography in diagnosis.

Background: Sturge-Weber syndrome (SWS) is primarily diagnosed in pediatric population, but clinical presentation in late adulthood is rarely reported. Evolution of radiological findings in the adulthood variant of SWS with isolated leptomeningeal angiomatosis has never been reported to our knowledge.

Case Presentation: We report here a case of an isolated temporo-parieto-occipital leptomeningeal angiomatosis on the right cerebral hemisphere in a sixty-two-year-old male who presented with generalized seizure, GCS score 14/15 (E4 V4 M6) with equal and reacting pupils, psychomotor slowing, left hemineglect and grade 4 power in the left upper and lower limbs.

Accuracy of the freehand (fennell) technique using a uniform entry point and sagittal trajectory for insertion of thoracic pedicle screws: A computed tomography-based virtual simulation study.

Background: Thoracic spine has complex pedicle anatomy with a narrow canal diameter which makes pedicle screw insertion challenging. Fennell et al. have described a simple freehand technique of thoracic pedicle screw placement.

Changing trends of presentation of central nervous system tuberculosis: Relative prevalence of cranial and spinal tuberculosis and drug resistance patterns.

Objective: Inappropriate use of antituberculosis drugs and a poor compliance has led to an increase in the prevalence of resistant Mycobacterium tuberculosis. The aim of this study was to document the changing trends in clinical presentation and drug resistance in patients with tuberculosis (TB) of the brain and the spine.

Materials And Methods: The authors retrospectively analyzed data from 243 patients admitted in a neurosurgical unit for surgical management of TB of the brain and spine from 2000 to 2013.

Patient-specific interactive software module for virtual preoperative planning and visualization of pedicle screw entry point and trajectories in spine surgery.

Background: Lumbar pedicle screw insertion involves a steep learning curve for novice spine surgeons and requires image guidance or navigation. Small volume centers may be handicapped by the lack of cost-effective user-friendly tools for preoperative planning, guidance, and decision making.

Objective: We describe a patient-specific interactive software module, pedicle screw simulator (PSS), for virtual preoperative planning to determine the entry point and visualize the trajectories of pedicle screws.

Primary Intradural Extramedullary Cervical Spinal Cysticercosis.

Background: Spinal cysticercosis has been reported in 0.7%-3.0% of patients with neurocysticercosis.

Neurogenic Pulmonary Edema in Traumatic Brain Injury.

A 29-year-old male admitted with severe traumatic brain injury following a road traffic accident was sedated and ventilated uneventfully for 72 h. On the fourth posttrauma day, after stopping sedation to assess readiness for extubation, he developed sudden onset desaturation; arterial blood gas showed severe diffusion defect with very low PaO/FiO ratio following an episode of generalized tonic-clonic seizure. The differential diagnoses and further management are discussed.
