Solitary fibrous tumor of the sinonasal cavity: CT and MR imaging findings.
SFT is a rare lesion of the sinonasal cavity. We retrospectively reviewed 5 patients with histopathologically proved sinonasal SFTs to determine their CT and MR imaging features. All patients underwent paranasal sinus CT and MR imaging. ⋯ The lesions showed heterogeneously marked enhancement on postenhanced MR images. Four patients underwent dynamic contrast-enhanced MR imaging, and the TICs showed a washout pattern. A familiarity with the imaging findings of sinonasal SFT may help to diagnose this entity.

Case Reports Clinical TrialWEB device for endovascular treatment of wide-neck bifurcation aneurysms.
The WEB is an intrasaccular flow disrupter dedicated to EVT of IA. We report our initial experience in a series of patients treated with this device. ⋯ In this initial series of patients, EVT of wide-neck bifurcation IAa with the WEB was feasible. Further studies are needed to evaluate the indications, safety, and efficacy of this new technique.

Clinical TrialPET findings of intramedullary tumors of the spinal cord using [18F] FDG and [11C] methionine.
Only a few reports on intramedullary tumors of the spinal cord using PET have been published. We report findings of PET by using [(18)F] fluorodeoxyglucose and [(11)C] methionine and discuss the usefulness of the findings in patients with intramedullary tumors of the spinal cord. ⋯ Both FDG and MET accumulated to a large degree in an anaplastic astrocytoma and accumulated in ependymomas (excluding a myxopapillary ependymoma). FDG can accumulate in tumors with hemorrhage. More investigation of a larger number of patients is required to evaluate the diagnostic value of PET with FDG and MET for imaging intramedullary tumors of the spinal cord.

Endovascular repair of traumatic cervical internal carotid artery injuries: a safe and effective treatment option.
The appropriate choice of treatment for traumatic extracranial carotid artery injury is still debated. The purpose of this study was to evaluate outcomes of endovascular carotid repair with regard to vessel patency and retreatment rates. ⋯ In our series, endovascular therapy was a safe and effective option for restoring luminal caliber and eliminating flow within pseudoaneurysms related to traumatic injuries. Imaging follow-up of all cervicocerebral vascular injuries is especially important within the first 45 days, a critical interval during which most lesions demonstrate healing or progression.
