To describe the operative methods and to investigate the efficacy of ventral neural decompression under microscopic vision with oblique lumbar interbody fusion (OLIF). ⋯ Microscopic ventral neural decompression with OLIF could achieve satisfactory clinical results with minimal complications in selected patients with extruded or sequestered disk.

Acquired pial arteriovenous fistula (pAVF) is an extremely rare intracranial vascular malformation, with few case reports in the English literature. This study presents a thorough review and analysis of all acquired pAVF cases from the literature in addition to an illustrated case. ⋯ Acquired pAVF is highly correlated with sentinel neurosurgical procedures or venous occlusion events. These lesions should be regarded as a different disease entity from primary pAVF because of the relatively low-flow shunting and benign clinical course.

Traumatic brain injury (TBI) remains a life-threatening condition characterized by growing incidence worldwide, particularly in the aging population, in which the primary goal of treatment appears to be avoidance of chronic institutionalization. ⋯ The eTBI Score is the first scoring system designed specifically for older adults. It could constitute a framework for clinical decision-making and serve as an outcome predictor. Its capability to stratify risk provides reliable criteria for assessing efficacy of TBI management.

The fornix is a region of greatest neurosurgical interest in regards to its complex anatomy and surgical approaches to this area. The objective of this study was to evaluate the morphology of the triangular recess (TR) and its role in the growth pattern of the colloid cysts (CC) within the third ventricle and in the choice of the surgical approach for their removal. Furthermore, to compare the results of the dissections with measurements performed on a magnetic resonance imaging scan. ⋯ The anatomy of the TR influences the growth pattern of CC within the ventricular cavity and determines the surgical strategy for their removal.

Case Reports
An unusual cause of trigeminal neuralgia: The first report of intracranial migration of a spinal cord stimulator.
Spinal cord stimulation has been shown to be an effective treatment for some patients diagnosed with chronic pain and failed back syndrome. However, lead migration from the implantation site is a potential complication that may reduce treatment efficacy, produce unintended symptoms, and require invasive and costly surgical replacement or removal. ⋯ Although spinal cord stimulation has demonstrated effectiveness as a treatment for chronic pain, care must be taken to ensure that the spinal cord stimulator leads are properly placed within the epidural space and are firmly anchored to avoid migration. Intracranial migration of a spinal cord stimulator lead poses significant risks for injury to adjacent cortical structures and may produce pain syndromes including trigeminal neuralgia.
