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.

Case Reports
Neoplastic cerebral aneurysm from metastatic lung adenocarcinoma with neuroendocrine features.
Neoplastic cerebral aneurysms are exceedingly rare. We describe a case of a ruptured, distal middle cerebral artery aneurysm as the presenting symptom leading to the identification of metastatic lung cancer. ⋯ Neoplastic cerebral aneurysms are rare, and there are insufficient data to support specific guidelines for management. This case is novel as the patient received adjuvant stereotactic radiosurgery to the operative bed, as well as systemic chemotherapy, and has maintained good functional status as of last follow-up at 6 months.

Visualization of the anatomy in minimally invasive surgery (MIS) of the spine is limited and dependent on radiographic imaging, leading to increased radiation exposure to patients and surgical staff. Ultra-low-radiation imaging (ULRI) with image enhancement is a novel technology that may reduce radiation in the operating room. The aim of this study was to compare radiation emission between standard-dose and ULRI fluoroscopy with image enhancement in patients undergoing MIS of the spine. ⋯ ULRI with image enhancement has the capacity to significantly decrease radiation emission in minimally invasive procedures without compromising visualization of anatomy or procedure safety.
