Meta Analysis
A meta-analysis on the clinical significance of redundant nerve roots in symptomatic lumbar spinal stenosis.
Symptomatic lumbar spinal stenosis (LSS), which leads to severe socioeconomic consequences and places a heavy burden on global healthcare system, is a relatively frequent spine disorder. Redundant nerve roots (RNRs) are a relatively common finding in which slender, serpiginous, or tortuous nerve roots are found in the subarachnoid space of the lumbar spine. Previous studies that evaluated the prognostic assessment of RNRs in patients with symptomatic LSS are composed of doubtful results. Therefore, the clinical significance of RNRs in symptomatic LSS is still uncertain. The aim of this meta-analysis is a systematic assessment of the clinical significance of RNR syndrome in symptomatic LSS. ⋯ RNR is an entity in association with symptomatic LSS, which may be viewed as a potentially powerful prognostic indicator of worse postoperative functional recovery for symptomatic LSS.

Review Case Reports
A primary pigmented choroid plexus papilloma located within the sella turcica: case report and literature review.
Choroid plexus papillomas (CPPs) are rare benign tumors, and the pigmented subtype is observed even more rarely. ⋯ This case study provides important clinical information for the evaluation, diagnosis, and treatment of pigmented CPP in the sellar region.

Review Case Reports
A UK confirmed case of Hirayama's disease in a young Caucasian male presenting with hand weakness.
We present the first reported case of Hirayama disease in the United Kingdom. A literature review of Hirayama disease in the Western literature shows that this case is unique in being the first in the United Kingdom, constituting one of only a few cases in Europe with supporting magnetic resonance imaging and reported treatment outcome. ⋯ This case lends further evidence to the flexion-induced myelopathy theory of Hirayama disease and supports the findings of other studies in which avoidance of neck flexion and cervical immobilization helped to attenuate disease progression in this patient group.

Review Case Reports
Intraventricular Cavernomas of the Third Ventricle: Report of Two Cases and a Systematic Review of the Literature.
Intraventricular cavernous malformations are relatively rare benign vascular malformations. Patients may be asymptomatic or present with headache, seizure, hemorrhage, or neurologic deficits. We report 2 cases of patients with cavernomas in the third ventricle and at the foramen of Monro. We also performed a systematic review of the literature to examine the clinical features and efficacy of the current standard of care for these lesions. ⋯ The specific location of the cavernoma determines clinical features seen and approach used in surgical resection. Ventriculoperitoneal shunting was not required in most cases, as hydrocephalus improved with removal of the obstruction at the foramen of Monro. Gross total resection appears to be the optimal management strategy in symptomatic patients and leads to a good outcome in most cases.

Glioblastoma multiforme (GBM) is the most common primary malignant brain tumor in adults, occurs most commonly in individuals older than 65 years of age, and is universally fatal. Increasing age compounds the poor prognosis of GBM, as elderly patients have markedly worse outcomes than younger patients. However, many of the studies previously investigating optimal treatment regimens exclude patients older than the age of 65 years and thus may not represent the best approaches to ensuring prolonged survival with preserved quality of life. This review aims to highlight the current literature on surgical and medical management, including our own experience, for GBM in the elderly patients, and to provide rational treatment approaches for a vulnerable, often-overlooked, patient population.
