Developmental venous anomaly (DVA) is the most common type of intracranial vascular malformation. These lesions are benign and are considered to be non-pathological variants of normal deep parenchymal veins. ⋯ The authors present an interesting case of biventricular hydrocephalus secondary to a DVA located on the proximal aqueduct in an adolescent patient. This case is discussed with in corroboration with current literature and management recommendations.

Thoracolumbar burst fractures in patients with neurological deficit: Anterior approach versus posterior percutaneous fixation with laminotomy.
Thoracolumbar burst fractures (TLBFs) are the most common spinal trauma; however, their appropriate management has not yet been determined. In this study, we aimed to compare the clinical and radiological results of percutaneous pedicle screw fixation (PPSF) following posterior decompression technique versus anterior corpectomy and fusion technique for the treatment of TLBFs. ⋯ Spinal canal decompression through small laminectomy followed by PPSF in the treatment of TLBFs with neurological deficits offers excellent clinical and radiological improvement as well as biomechanical stability. Furthermore, this can be a safe and effective surgical option with the advantage of less invasiveness in the treatment of TLBFs.

Gunshot wounds (GSW) are one of the most lethal forms of head trauma. The lack of clear guidelines for civilian GSW complicates surgical management. We aimed to develop a decision-tree algorithm for mortality prediction and report long-term outcomes on survivors based on 15-year data from our level 1 trauma center. ⋯ Favorable long-term outcomes (mean follow-up 34.4 months) were possible for survivors who required neurosurgery and stable patients who were conservatively managed. We applied clinical and radiological characteristics that predicted survival to construct a decision-tree to facilitate surgical decision-making for GSW. Further validation of the algorithm in a large patient setting is recommended.

In spinal oncology traditional titanium implants could significantly impair evaluation of postoperative imaging because of artifacts, potentially affecting proper planning and execution of radiotherapy and adequate radiological follow-up to rule out progression of the disease. This is why carbon fiber reinforced (CFR)-PEEK implants have been developed for spinal fixation. The advantages of this system include fewer artifacts on imaging, potentially improving the execution and quality of radiotherapy, with also a reduced scattering effect to neighboring tissues. ⋯ CFR-PEEK implants constitute a feasible and effective way to restore stability in metastatic spine tumors. This study found a non inferior favorable profile in terms of intraoperative and postoperative complications and functional recovery, compared to titanium. Further prospective studies are needed to clarify the potential oncological advantage of their radiolucency.

Immune checkpoint inhibitors, also known as immunotherapy, have revolutionised the treatment of metastatic melanoma, but are frequently associated with immune-related adverse events (irAEs) affecting a variety of organ systems. Here, we present a case of a patient with metastatic melanoma, being treated with combination ipilimumab-nivolumab, who developed a foot drop. ⋯ The patient had other irAEs, which warranted cessation of immunotherapy and the introduction of corticosteroids, and this also resulted in improvement in the patient's lower limb symptoms and MRI appearances. This confirmed an autoimmune polyradiculitis - a rare irAE.
