The purpose of this study was to compare the efficacy, stability, and safety of stent-assisted coiling (SAC) and balloon-assisted coiling (BAC) in the treatment of ruptured wide-necked aneurysms in the acute period. ⋯ These findings suggested that SAC was more appropriate than BAC for ruptured wide-necked aneurysms with lower fundus/neck ratio or wider neck size. However, periprocedural complications, occlusion rates, and favorable outcomes did not differ between the 2 techniques.

To identify the prognostic factors associated with patient satisfaction after double-door laminoplasty for cervical compression myelopathy due to ossification of the posterior longitudinal ligament (OPLL). ⋯ Patient satisfaction after laminoplasty was insufficient in patients with a hill-shaped ossification. The patients with OPLL who were able to recognize a difference in their clinical physical function, especially lower extremity function, were satisfied after laminoplasty.

The caudal zona incerta (cZI) is an increasingly popular deep brain stimulation (DBS) target for the treatment of tremor-predominant disease. The dentatorubrothalamic tract (DRTT) is a white matter fiber bundle that traverses the cZI and can be identified using diffusion-weighted magnetic resonance imaging fiber tractography to ascertain its precise course. In this report, we compare 2 patient cases of cZI DBS, a responder and a nonresponder. ⋯ Preoperative diffusion-weighted magnetic resonance imaging fiber tractography imaging of the DRTT has the potential to improve and individualize DBS planning.

We present the largest known consecutive series of patients with epidural lipomatosis (EL) to characterize demographics and clinical symptoms of patients with EL on magnetic resonance imaging (MRI), and compare these characteristics against a matched control group. ⋯ Patients with lumbosacral EL tend to be obese with a high incidence of type 2 diabetes mellitus, suggesting that this pathology may be a sequela of metabolic syndrome. Future research topics should include the pathogenesis of EL, as well as treatment outcomes of surgical versus primary care management.

To determine the relationship between the severity of stenosis graded using both surgeons' visual assessment of spinal stenosis as well as measurement of dural cross-sectional area on magnetic resonance imaging (MRI), with the patient's disability. ⋯ Although surgeons rely on visual assessment of the severity of stenosis while making surgical decisions, we found that objective and subjective imaging parameters to grade severity of stenosis did not consistently indicate the patient's disability level.
