It remains unclear whether stereotactic radiosurgery (SRS) offers the same benefit for patients with type 2 trigeminal neuralgia (TN2) as for those with type 1 trigeminal neuralgia (TN1). The objective of this study is to compare the outcomes of patients with TN1 and TN2 after SRS. ⋯ SRS offers similar rates of initial pain relief, pain score distribution, pain recurrence, and time to pain recurrence between patients with TN1 and TN2. The time to initial pain relief was longer for patients with TN2.

Perimesencephalic hemorrhage (PMH) is a type of subarachnoid hemorrhage with excellent long-term outcomes. Only 1 well-documented case of in-hospital rebleeding after PMH is described in the literature, which occurred after initiating antithrombotic treatment because of myocardial ischemia. We describe a patient with PMH without antithrombotic treatment who had 2 episodes of recurrent bleeding on the day of ictus. To validate the radiologic findings, we conducted a case-control study. Six neuroradiologists and 2 neuroradiology fellows performed a blinded assessment of serial unenhanced head computed tomography (CT) scans of 8 patients with a perimesencephalic bleeding pattern (1 index patient, 6 patients with PMH, 1 patient with perimesencephalic bleeding pattern and basilar artery aneurysm) to investigate a potential increase in amount of subarachnoid blood. ⋯ Recurrent bleeding after PMH may also occur in patients not treated with antithrombotics. Even after early rebleeding, the prognosis of PMH is excellent.

Leisure sports activities are assumed to be safe. It is however possible that participation in contact sports as leisure activity may also affect the space available for the cervical cord (SAC). The objective of this study is to compare the SAC of asymptomatic young adults involved in active leisure contact sports with matched controls that do not participate in contact sports. ⋯ Participation in leisure contact sports has a small but overall negative effect on the SAC, especially at the upper subaxial cervical spine levels. This effect is most marked after the age of 40 years. Overall, there was no sex difference observed.

The incidence of postoperative stroke after carotid endarterectomy is an uncommon event, and differences by racial and ethnic subgroups are not described fully in the literature. ⋯ There was no difference between the racial and ethnic groups and the proportion of postoperative stroke among patients undergoing revascularization for asymptomatic carotid stenosis.

Hydrocephalus is a common sequelae of aneurysmal subarachnoid hemorrhage (aSAH). However, in daily routine it is difficult to predict a patient's need for ventricular shunt placement in the course of the disease. ⋯ Our data suggest that the volume of the third ventricle in the initial CT is a strong predictor for shunt dependency after aSAH.
