Review Case Reports
Bullough's lesion: an unexpected diagnosis after the resection of a slowly growing osseous-like retroauricular bump. Case report and review of the literature.
We describe the case of a 33-year-old woman with a history of over 15 years of a slow growing firm osseous-like right retroauricular mass. Surgical resection was easily performed using a sharp technique, because of a clear cleavage plane. ⋯ Clinical differential diagnosis must be done with osteoma, periosteal chondroma, and other fibro-osseous lesions such as fibrodysplasia and ossifying fibroma. Because of the paucity of data, the natural history of this lesion is unknown and serial clinical and radiological follow-up is advised.

Flow diverter stents have become a useful tool for treatment of complex intracranial aneurysms. A serious complication is incomplete wall apposition after flow diverter placement. The aim of this study was to present a comprehensive investigation of hemodynamic changes induced by incomplete expansion of a flow diverter. ⋯ The results of this study can be considered during treatment planning of complex cases where the risk of incomplete flow diverter expansion exists. Further studies are required before results can also be used to support the decision process about antiplatelet therapy and additional interventions to improve wall apposition.

Artery stenting is an effective therapy for carotid artery stenosis to prevent ischemic stroke. We aimed to identify and analyze the 100 top-cited reports on carotid artery stenting (CAS) to review the achievements and developments in this field. ⋯ The results of the present study provide scientific data for CAS. The United States contributed the most reports. Stroke was the lead productive journal. Those reports with a greater impact factor were likely to be cited more often.

To investigate the relationships between sagittal alignment parameters and Neck Disability Index (NDI) scores after adjacent 2-level anterior cervical diskectomy and fusion (ACDF) and to study the impact of the T1 slope (T1s) minus C2-7 lordosis (T1s-CL). ⋯ Changes in cervical sagittal parameters after 2-level ACDF were associated with quality of life. A greater T1S-CL mismatch was related to a greater degree of cervical malalignment. T1s-CL may be a more important predictor of cervical malalignment than C2-7 SVA. Specifically, a mismatch greater than 28.07 corresponded to positive cervical sagittal malalignment, defined as an NDI score greater than 25.

A meta-analysis of randomized controlled trials (RCTs) was performed to compare the incidence of cement leakage between unilateral and bilateral percutaneous vertebral augmentation (PVA) in treating osteoporotic vertebral compression fractures (OVCFs). ⋯ The results of our meta-analysis have provided sufficient evidence to show that the unilateral approach can decrease the incidence of cement leakage in PVA. We believe the unilateral approach could reduce the risk of cement leakage owing to the lower cement dosage in the treated vertebra.
