To identify whether age, sex, and lesion location are associated with initial presentation in patients with brain arteriovenous malformations (AVMs). ⋯ Initial AVM presentation varied with patient age, sex, and AVM locations. Younger age, female sex, and deep and infratentorial locations may be associated with initial hemorrhage. Male sex and frontal, temporal, and parietal AVM locations may be predictors of initial seizure. Chronic headache was more likely to occur in patients with AVMs involving the occipital lobe.

Lumbar arthrodesis is a surgical option for treatment of lumbar pathologies. Stability of the spinal construct partly depends on load-bearing support from back muscles. Despite the role of the psoas muscle in upright spinal stabilization, data describing its clinical significance are scarce. We evaluated the effects of the psoas muscle thickness on outcomes after lumbar fusion surgery. ⋯ This study shows that the psoas muscle can be beneficial in overall postoperative rehabilitation with early ambulation and greater improvement in functional outcomes. Given the role of the psoas muscle in spinal stabilization, the effect of psoas muscle thickness on postoperative functional outcomes warrants further investigation.

Head and neck tumors are a heterogeneous group and often invade the skull base. Various radiation techniques can be used for these tumors when surgery is unavailable. This study investigated the indications for gamma knife radiosurgery (GKRS) in benign head and neck tumors. ⋯ GKRS is a reasonable alternative to surgery that can effectively control tumor growth and preserve functions of the head and neck in primary, residual, or recurrent benign head and neck tumors.

Meningiomas arising in pediatric populations are rare neoplasms with distinct biological and clinical features. A rare case of a 2-year-old boy with extremely large intracranial parasagittal meningioma is presented. To our knowledge, this case is the largest parasagittal meningioma to be reported to date in the pediatric age group. ⋯ The patient's postoperative recovery was unremarkable, and the previously compressed brain rebounded. There was no evidence of recurrence after two years of follow-up. Every effort should be exerted to achieve radical resection of the tumor, which can result in a satisfactory prognosis and a low recurrence rate.

Management of Incidental Dural Tear During Lumbar Spine Surgery. To Suture or Not to Suture?
Incidental durotomy (ID) during lumbar spine surgery is a frequent complication of growing clinical relevance as the number and complexity of spinal procedures increases. Yet, there is still a lack of guidelines for the treatment of ID with a large heterogeneity of established surgical techniques. The aim of this study was to investigate the efficacy of dural suturing in patients having ID during degenerative lumbar spine surgery, compared with other dural closure techniques. ⋯ Based on our results, the dural closure technique after ID does not seem to influence revision surgery rates due to cerebrospinal fluid leakage and its complications. Further prospective randomized studies are needed to confirm our results.
