We report a young adult man who presented with chronic raised intracranial tension features and unusually progressive bilateral visual and hearing impairment of 18 months duration. MR imaging showed extensive dural involvement and contiguous orbital and spinal disease. Cerebrospinal fluid demonstrated persistent high lymphocytic pleocytosis. Dural biopsy obtained from posterior cervical approach with C1 arch excision and meningeal biopsy revealed features of classical of Rosai-Dorfman disease. Histiocytes were strongly positive for CD-68 and S-100 proteins. The illness relentlessly progressed with patient developing total deafness and near total blindness at last follow-up.

Introduction: Pneumocephalus and pneumorrhachis are rare postoperative complications, commonly occurring within a few days to months after spinal surgery. They are very rarely reported after thoracic surgeries. This case highlights a unique presentation in the emergency department involving headache and vomiting caused by late complications following thoracic surgery with a titanium rib implant.

Background: Correct identification of the epidural space requires extensive training for technical proficiency. This study explores a novel bimanual haptic simulator designed for the precise insertion of an epidural needle based on loss-of-resistance (LOR) detection, providing realistic dual-hand force feedback.
Methods: The simulator, equipped with two haptic devices connected to a Tuohy needle and an LOR syringe, was designed to simulate the tissues' resistive forces felt by the user during the procedure, offer anatomical variability and record detailed performance metrics for personalized feedback.

Dural venous sinus thrombosis, a subset of cerebral venous thrombosis, is an important pathology due to its significant morbidity and mortality. This process has an annual incidence of three to five cases per million adults. Although copious predisposing factors exist, the core principles revolve around Virchow's triad: venous stasis, hypercoagulability, and vascular endothelial damage.

Background: Dural metastasis (DM) remains one of the most challenging clinical scenarios in breast cancer treatment. To date, no clear standard care of dural metastases has been established. We sought to identify the progression pattern or treatment strategies that could possibly improve prognosis of breast cancer patients with DM.
