Pleomorphic xanthoastrocytomas are rare tumors of glial origin comprising <1% of all astrocytic tumors of brain. These tumors are rare in the infratentorial compartment and were not known to arise from the middle cerebellar peduncle. ⋯ We also discuss the histopathologic features of these tumors suggesting their resemblance to other maldevelopmental tumors, the rarity of pure World Health Organization grade II pleomorphic xanthoastrocytoma in the infratentorial compartment, as well as the appropriate management.

The total number of citations of a research article can be used to determine its impact on the scientific community. We aimed to identify the top-100 articles published on ischemic stroke and evaluate their characteristics. ⋯ Our list of top-100 citation classics specific to ischemic stroke provide a detailed insight into academic achievements, historical perspective and serves as a guide for the scientific progress in stroke.

We reviewed our clinical experience of patients with moyamoya disease (MMD) who gave birth and assessed characteristics of those experiencing neurologic deterioration. ⋯ Patients with severely reduced regional cerebrovascular reserve on single-photon emission computed tomography and frequent TIAs before pregnancy may experience neurologic deterioration during pregnancy, delivery, and puerperium. Surgical revascularization before pregnancy may decrease neurologic deterioration during these periods.

Deep brain stimulation (DBS) is an effective therapeutic modality; however, only a percentage of eligible patients undergo the procedure. ⋯ Frame placement, awake surgery, and head shaving did not appear to play a significant role in most patients' decision-making process to undergo DBS, as analyzed in this retrospective cohort. The majority of patients were satisfied with the procedure and reported being comfortable. Managing goals and expectations preoperatively played a significant role in ultimate overall satisfaction.

De Novo Spinal Dural Arteriovenous Fistula in a Patient with a Lipomyelomeningocele: Case Report.
Spinal dural arteriovenous fistula (AVF), the most common type of spinal vascular malformation, tends to manifest as progressive myelopathy over several years. Spinal dural AVFs are considered an acquired lesion and, in contrast to spinal arteriovenous malformations, are not often associated with other anomalies. The presence of a spinal dural AVF in the setting of a lipomyelomeningocele and tethered cord is extremely rare. Both lesions tend to cause similar symptoms, and patients with concomitant lesions generally require surgical intervention for both. ⋯ In this case report, we present evidence of de novo development of a spinal dural AVF associated with a lipomyelomeningocele. In addition, this is the second documented patient in the literature with a lipomyelomeningocele and concomitant dural AVF who did not undergo detethering of the cord as part of treatment.
