Review Case Reports
Predictors of outcomes in fourth ventricular epidermoid cysts: A case report and a review of literature.
To present an illustrative case of fourth ventricular epidermoid cyst and review the literature to identify predictors of surgical outcomes. ⋯ Our review found that in patients with fourth ventricular epidermoid cysts, unfavorable outcomes were predicted by older age and by longer intervals from symptom onset to diagnosis. Clinicians should maintain a high index of suspicion for fourth ventricular epidermoid cysts in patients presenting with cerebellar signs and visual disturbances.

Review Case Reports
Results of Atypical Hemifacial Spasm with Microvascular Decompression: 14 cases reported and lectures reviewed.
Few studies have examined atypical hemifacial spasm (AHFS), and the mechanism of AHFS remains unclear. In this study, we examined the etiology, prognosis, and treatment of AHFS. ⋯ Most of the cases of AHFS studied here were caused by neurovascular conflict in zone IV of the facial nerve distal to the root entry zone. MVD surgery is the first choice treatment for AHFS.

Although performing deep brain stimulation (DBS) with the patient under general anesthesia without microelectrode recording (MER) or intraoperative test stimulation (ITS) for movement disorders ("asleep" DBS) has become increasingly popular, its feasibility is based on the untested assumption that stereotactic accuracy correlates with positive clinical outcomes. To investigate outcomes after asleep DBS without MER or neurophysiological testing, we reviewed the medical literature on the topic. ⋯ Initial evidence suggests that asleep DBS can be performed safely for PD and ET with good clinical outcomes. Long-term follow-up, larger cohorts, and double-armed studies are needed to validate these initial results.
