Magnetic resonance guided laser interstitial thermal therapy (MRgLITT) is a new minimally invasive treatment for Tuberous Sclerosis Complex (TSC) associated epilepsy in children. This video describes a case of a 17-year-old girl with TSC-associated drug resistant epilepsy treated with robotic-assisted MRgLITT. In our case, MRgLITT was safe and effective in simultaneous targeting multiple epileptic tubers in one single procedure, leading to a marked decrease in seizure frequency. MRgLITT could be a promising and more appealing treatment option for children who may need multiple surgeries over their lifetime due to the progressive nature of TSC.

Flow diverters (FDs) carry the risk of thromboembolic complications associated with the device and bleeding complications associated with dual antiplatelet therapy. We hypothesize that an antithrombotic surface coated flow diverter(BSCFD) would have less acute thrombus formation and better endothelialization on the device surface compared to uncoated flow diverter. ⋯ In the rabbit model, the BSCFD is associated with less thrombus formation at acute stage, less inflammation, less vessel injury and better endothelialization on the device surface compared to the PFD.

The evaluation of hypomagnesemia's significance in predicting the presence of the black hole sign in patients with intracranial hemorrhage (ICH) is currently under investigation. ⋯ The presence of hypomagnesemia may serve as a predictive factor for the black hole sign and rebleeding in patients with intracerebral hemorrhage (ICH), thereby providing valuable guidance for clinical treatment.

Trigeminal neuralgia is a debilitating disease, with severe recurrent paroxysms of shock-like facial pain. Although pharmacotherapy may suffice in the majority of cases, a proportion of patients require surgical treatment. Gamma knife radiosurgery (GKRS) represents a potential non-invasive alternative to surgery in these patients. ⋯ GKRS is effective among patients with classic/idiopathic TN, with complete pain relief in 58.6% of patients, and adequate pain relief in 18.6% of patients. The most frequent complication is facial hypesthesia, affecting 38.6% of patients. Multiple prior failed procedures for TN significantly predict failure of pain relief at latest follow-up.

Arachnoid cysts are benign, intradural collections of cerebrospinal fluid that are often asymptomatic but, in rare instances, will grow and may cause symptoms. When these are in the posterior fossa, the symptomatology greatly ranges, and the indications for surgery are not well defined. The objective of this study is to examine radiographic and symptomatic outcomes following surgery for posterior fossa arachnoid cysts (PFAC). ⋯ Although there is a high rate of radiographic improvement for PFAC surgery, there is a wide variety of presenting symptoms with differing postoperative improvement rates. This study reinforces the importance of preoperative counseling regarding symptomatic outcomes for PFAC surgery, with supporting statistical analysis but limited by the sample sizes available.
