Review Case Reports
Spontaneous regression of a hypoglossal neurinoma: a case report and review of the literature.
Hypoglossal neurinomas are very rare intracranial tumors. The management choices include surgery, as the gold standard, and radiosurgery or a combination of both. Little is known about this condition and the behavior of this tumor. ⋯ Our case highlights the importance of considering careful observation and diligent follow-up as a treatment option, as these lesions can show spontaneous regression with no invasive approaches.

Review
Role of hemodynamics forces in unruptured intracranial aneurysms: An overview of a complex scenario.
An understanding of the natural history of unruptured intracranial aneurysms (IAs) has always played a critical role in presurgical or endovascular planning, to avoid possibly fatal events. Size, shape, morphology, and location are known risk factors for rupture of an aneurysm, but morphologic parameters alone may not be sufficient to perform proper rupture risk stratification. ⋯ The role of hemodynamic forces in evaluation of the natural history of unruptured IAs presents is inherently complex and is still not completely understood. In this complex scenario, although several attempts have been described in the literature, a proper risk rupture stratification and treatment strategy selection based on hemodynamic forces has not yet been created. Further efforts should be made to accomplish this important goal.

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.
