Tentorial dural arteriovenous fistulas have an increased risk of rupture and hemorrhage, and therefore require urgent treatment to occlude the fistula and proximal venous drainage. This is usually accomplished via endovascular treatment. We present a case of a Cognard grade IV dural arteriovenous fistula that presented as trigeminal neuralgia. This video showcases the angiographic vascular composition of the lesion with main feeders coming from the middle meningeal artery and the tentorial artery of Bernasconi and Cassinari. Details, benefits, and risks of the procedure were thoroughly discussed with the patient and consent was obtained prior to the procedure. We performed endovascular Onyx embolization through a distal branch of the right middle meningeal artery. We were able to successfully occlude the lesion using Onyx embolization and the patient had significant improvement of her pretreatment trigeminal neuralgia.
Stereotactic radiosurgery (SRS) offers a noninvasive technique for division of the corpus callosum, which can confer improved seizure control to patients suffering from frequent atonic seizures due to rapid interhemispheric generalization. This noninvasive approach is well-suited for use in a palliative intervention for improved seizure control in this patient population. To our knowledge, this is the first report of radiosurgical completion corpus callosotomy in an adult in the United States.
A 20-year-old ambidextrous nonverbal man with a history of refractory generalized epilepsy status post open anterior corpus callosotomy at age 10 years, Lennox-Gastaut syndrome, and autism presented after 2 years of incremental, progressive deterioration in seizure control and behavior including 1 year. The family decided to pursue SRS corpus callosotomy. Under general anesthesia, a volume of interest encompassing a full midsagittal plane of the corpus callosum was defined to deliver 60 Gy to the 50% isodose line fully encompassing the target. Gamma Knife was used with 2 isocenters at 90° and 1 at 110° and isodose lines of 60, 20, and 12 Gy. Treatment was carried out without difficulty or complications while the patient remained under close monitoring. Ridaforolimus The patient was discharged the next day with a 2-week taper of dexamethasone.
Eight months postradiosurgical corpus callosotomy, the patient is free of atonic seizures and is ambulatory. In carefully selected cases and with protective radiosurgical planning, SRS for completion corpus callosotomy represents an effective option for refractory seizure control.

Rosai-Dorfman disease (RDD) is a rare pathologic entity caused by sinus histiocytosis with massive cervical lymphadenopathy. Isolated spinal involvement is an infrequent presentation of extranodal RDD. The clinical and radiologic appearance of RDD represents a diagnostic challenge. We report 2 patients with paraparesis caused by RDD of the thoracic spine and a PRISMA-style systematic review.
There were 2 patients with isolated extranodal thoracic spinal RDD without cervical lymphadenopathy. One patient presented with anterior thoracic RDD and a subtotal resection. The small residual disease completely responded to the postoperative course of steroids. The second patient had extradural thoracic spine RDD, which was resected completely. A 6-month postoperative follow-up magnetic resonance imaging (MRI) scan showed local recurrence, which responded to radiation therapy. Five years follow-up of both patients showed normal neurologic functions and no recurrence on MRI scan surveillance.
RDD is a rare occurrence and should be considered in the differential diagnosis of extradural or intradural spinal lesions. Gross total resection is recommended, and long-term clinical follow-up with MRI is advised. Residual or recurrent RDD requires steroids or radiation therapy.

Return to work and driving are major rehabilitation goals for patients after an aneurysmal subarachnoid hemorrhage (aSAH). Our goal is to identify factors that may predict return to work or driving after aSAH.
Medical records of patients with aSAH were retrospectively reviewed from 2010 to 2018. Information on return to work and driving were prospectively collected. Univariate analyses were performed to assess the association between return to work or driving with patient characteristics, social factors, and admission clinical and radiographic severity. Multivariate regression models were used to evaluate return to work and driving and generate predictive models.
A total of 193 patients were included, of whom 32% (62/193) resumed work and 57% (110/193) returned to driving. Median follow-up time was 3.4 years (interquartile range, 0.7-7.5 years). Return to work was associated with younger age (odds ratio [OR], 0.89; 95% CI, 0.85-0.94), lower Hunt and Hess grade (OR, 0.34; 95% CI, 0.23-0.54), and lack of seizures (OR, 0.09; 95% CI, 0.02-0.47). Return to driving was associated with younger age (OR, 0.94; 95% CI, 0.91-0.98), lower Hunt and Hess grade (OR, 0.36; 95% CI, 0.23-0.56), married status (OR, 3.4; 95% CI, 1.2-9.4), current or former smoking (OR, 3.9; 95% CI, 1.5-10.1), lack of recreational drug use (OR, 0.08; 95% CI, 0.01-0.77), and lack of seizures (OR, 0.28; 95% CI, 0.08-0.96). Admission risk factors were predictive of return to driving and return to work in the final multivariate models generated (area under the receiver operating characteristic curve 88% vs. 89%, respectively).
Because work may be highly dependent on complex individual and social factors, driving is a simple and more accurate assessment for an individual’s status after aSAH.
