Intrameningioma metastasis is a rare differential diagnosis. The clinical implications of these lesions are poorly understood. We screened our database to identify all patients who had been undergone surgery between January 2000 and December 2018 and had been diagnosed with intrameningioma metastasis. Medical charts and radiographic images were reviewed. Brain edema was related to tumor size on preoperative T2-weighted magnetic resonance imaging and classified as little (i.e., less than the tumor size), moderate (i.e., less than triple the size of the tumor), and extensive (i.e., more than triple the size of the tumor). ⋯ Intrameningioma metastases show an aggressive clinical behavior prompting early surgical intervention. Clinicians should be aware of this rare entity when counseling patients.

We proposed a novel prognostic tool for the prediction of in-hospital mortality based on a combination of hemodynamic parameters and biomarkers in patients with traumatic brain injury (TBI). We hypothesized that a combination of shock index (SI) with high sensitive troponin T (HsTnT), the Bio-Shock Index (Bio-SI), has better prognostic power than its individual components. ⋯ The Bio-SI is potentially a better tool than its individual components to predict in-hospital mortality among patients with TBI; however, HsTnT alone outperforms SI. Prospective studies and multicenter trials studying troponin levels and SI in all patients with TBI with the inclusion of outcome scores will prove or disprove the predictability of the new index.

Recurrent trigeminal neuralgia after successful microvascular decompression is not rare. ⋯ This case is an unusual type of recurrent trigeminal neuralgia because of a subsequently developed offending vessel within a short period.

Since the first report about nail gun injuries in 1959, there has been an average of approximately 37,000 patients hurt by nail guns and treated in emergency departments. Carotid arterial injury by nail gun has been reported, but vertebral artery damage is extremely rare. ⋯ Based on our experience and a review of the literature, in terms of treating a nail gun injury to the cervical spine, we would like emphasize that preoperative CT scan or CT angiogram is necessary to assess the location and shape of the nail, especially nails with barbers or washers. Improving awareness of the risk from accidental nail gun trauma may lead to better prevention of this rare but potentially life-threatening injury.

Hemostasis valves are commonly used in neurointerventions. We propose a novel concept for fixing hemostasis valves to the operating table during procedures. Moreover, we report our preliminary in vitro experience using these new devices created using a 3-dimensional printer. ⋯ HVHs should be more useful than conventional methods, particularly in cases requiring fine complementary control of both a microcatheter and microguidewire.
