Review Case Reports
Jugular bulb dysmaturation in torcular dural sinus malformation, clinical images and a review of literature.
We present unique clinical images of jugular bulb dysmaturation (JBD) in an infant with torcular dural sinus malformation (tDSM). Lasjaunias et al hypothesized that the former possess a pivoting role for development of the latter. ⋯ The combination of magnetic resonance imaging angiography, computed tomography angiography, and digital subtraction angiography imaging of JBD is unique. Moreover, we reviewed current tDSM literature and showed that the presence of JBD in tDSMs correlates significantly with a higher mortality.

The carotid sinus nerve branches off the glossopharyngeal nerve just after its appearance from the jugular foramen, descends along the internal carotid artery, and enters the carotid sinus. There have been many studies of the pathway and the course of the carotid sinus nerve and its communications with surrounding nerves. ⋯ Acknowledgment of its anatomic diversity can be important in specific operations dealing with this area. Herein we review the anatomy, variations, pathology, and clinical applications of the carotid sinus nerve.

Multicenter Study
Effect of Fetal Posterior Circulation on Efficacy of Flow Diversion for Treatment of Posterior Communicating Artery Aneurysms: A Multi-Institutional Study.
Flow diversion (FD) has emerged as an effective treatment modality for aneurysms of the posterior communicating artery (PCOM). Whether or not a fetal posterior circulation (FPC) affects PCOM aneurysm occlusion rates after FD remains undetermined. ⋯ Our results indicate reduced efficacy of FD for the treatment of PCOM aneurysms associated with a FPC. These findings may influence treatment selection for aneurysms at this location.

Review Case Reports
Resection of Pediatric Trigeminal Schwannoma Using Minimally Invasive Approach: Case Report, Literature Review, and Video Submission.
Trigeminal schwannomas are fifth cranial nerve tumors that originate from the nerve sheath. They rarely occur within the pediatric population and can cause dysfunction of the trigeminal nerve and surrounding structures. When patients become symptomatic, neurosurgeons should consider resection. ⋯ We present a rare case of pediatric trigeminal schwannoma type Mp treated surgically with a near-total resection via a novel mini-pterional approach and use of cranial nerve diffusion tensor imaging.

The objectives of this study were to report 4 cases diagnosed with trigeminal schwannomas (TS), among whom tumor in epidural space of middle fossa broke through dura mater into subdural space, and to analyze the potential reason for recurrence of TS in middle fossa after surgical removal by endoscopic endonasal approach (EEA) or interdural approach. ⋯ TS in middle fossa has been widely believed to be totally located at epidural space, whereas we found that it could occasionally breach into subdural space and accept blood supply from the pial artery. We believe this could be the potential reason for recurrence after tumor resection by EEA and interdural approach.
