We report a case of Mikulicz disease (MD), an immunoglobulin G4 (IgG4)-related disease that affects the lacrimal and salivary glands. IgG4-related disease is a relatively new clinical entity and is not commonly encountered by neurosurgeons. MD sometimes mimics intraorbital tumors such as malignant lymphoma but responds well to corticosteroid treatment. Thus it is important to recognize the clinical and radiographic features of MD.

There was no consensus regarding the treatment of intracranial chondrosarcoma (CSA). The study aimed to evaluate the adverse factors for progression-free survival (PFS) and overall survival (OS) and to propose a treatment strategy for CSA. ⋯ Intracranial CSAs were not completely amendable by surgery alone. Gross total resection as far as possible plus radiation were necessary for mesenchymal CSA and conventional CSA with active growth or residual tumor. Stereotactic radiosurgery was an alternative if proton therapy was unavailable. A future study with a large cohort is required to verify our findings.

To evaluate the effectiveness and safety of 2-isocenter Gamma Knife surgery (GKS) by reviewing patients with trigeminal neuralgia (TN) from the last 10 years. ⋯ Compared with other modalities, 2-isocenter GKS was a safe and highly effective option for patients with TN. However, more data need to be collected to verify its long-term effect.

Genetic risk factors can contribute to the etiology of intracranial aneurysms (IAs), and the genetic predisposition of IAs is largely unknown. Our study aimed to explore the role of rare variations in IA susceptibility. ⋯ LOXL2 c.C133T is a pathogenic mutation that is responsible for a fraction of familial IAs.

Emergency Optic Canal Decompression for Vision Salvage in Fibrous Dysplasia: A Case Report.
The most common neurologic manifestations of fibrous dysplasia (FD) are vision and hearing loss. Optic decompression for progressive vision loss has been shown to yield positive results in terms of visual outcomes; however, emergency optic decompression surgery for sudden loss of vision in FD has not to date been reported in the pediatric population. We report the first case of FD presenting with sudden vision loss and successfully managed with emergency optic decompression. ⋯ There is no consensus on the benefit and safety of prophylactic optic decompression, yet therapeutic decompression has been shown to prevent vision deterioration. Our findings suggest that therapeutic decompression even when done in the emergency setting yields positive results, while prophylactic decompression carries an inherent risk for loss of vision in a seeing eye.
