Epidural blood patch (EBP) of the dural sac is the mainstay definitive treatment for refractory cases and has mixed efficacy. We sought to evaluate the recent efficacy and outcomes of EBP for SIH at our institution.

Material And Methods: A retrospective study was performed on selected subjects who were more than 18 years of age, were diagnosed with infectious spondylodiscitis, underwent at least 2 spinal interventions for the diagnosis at the same level, and had MRI prior to each image-guided intervention. Both MRI studies were analysed for vertebral body changes, paravertebral collections, epidural thickening and collections, bone marrow signal changes, loss of vertebral body height, abnormal signal in intervertebral disc, and loss of disc height.
Minimally invasive vertebroplasty has arisen as a viable alternative treatment for pathologic vertebral body fractures. Vertebroplasty is well documented in the thoracic and lumbar spine from the posterolateral approach, but is rarely employed in the cervical spine in consideration of numerous critical neural and vascular structures that must be avoided. Careful technique and usage of imaging is necessary to maneuver crucial structures and minimize risk of complication.

Despite the high prevalence rate of this condition, it is still very poorly understood and often delayed in its diagnosis due to its variety in clinical manifestations. For our case, an eighteen-year-old male who was recently diagnosed with SLE presented with progressive confusion, visual and auditory hallucinations, in addition to high fevers, diarrhea, abdominal and flank pain.

Methods: Retrospective chart analysis was performed at a single institution from 2013 to 2019. Cases were separated by performance in the prone or lateral decubitus positions.
A 37-year-old female was admitted with worsening neurologic function. On arrival from an outside hospital, the patient was obtunded and intubated. Magnetic resonance imaging of the brain revealed nodular enhancement of the leptomeninges, intracranial osteolytic lesions, and diffuse vasogenic edema causing mass effect.

Treatment recommendations for spinal subdural hygromas are lacking.
Case Description: We report a case of a 30-year-old man who developed delayed-onset cauda equina syndrome after a motor vehicle accident.
Introduction: There is continued interest in identifying factors that predict a favorable outcome after endovascular thrombectomy (EVT) for anterior circulation large vessel occlusion (ACLVO). We compared the predictive values of 2 different scoring systems for evaluating venous collateral circulation.
Methods: A retrospective review of patients who underwent EVT for ACLVO at a single institution was performed.
There are few reliable morphologic indices to aid in the determination of an intracranial aneurysm's rupture risk. We sought to characterize morphological characteristics of aneurysm sacs and their lobes that are associated with ruptured status at time of initial evaluation with diagnostic angiography. These factors could be associated with an aneurysm's risk of rupturing.

We summarize our experience with ROSE of USGFNA on head and neck nonthyroid lesions using telecytopathology.
Materials And Methods: Real-time images of Diff-Quik stained cytology smears were obtained at ultrasound suite with an Olympus DP-70 digital camera attached to an Olympus CX41 microscope, and transmitted via ethernet by a cytotechnologist to a cytopathologist in cytopathology laboratory who rendered a preliminary diagnosis.
We describe the case of a 61-year-old patient with significant medical co-morbidities and tortuous vascular anatomy presenting with a large middle cerebral artery aneurysm. To avoid the risks of general anesthesia and circumvent a majority of the tortuous vessels, the aneurysm was accessed by direct open exposure of the common carotid artery under conscious sedation and local anesthesia. We were able to achieve complete endovascular occlusion of the aneurysm and the patient tolerated the procedure well with no intra- or post-operative complications.

Outcome from such treatment can be very successful and gratifying if the intervention is timely and patient selection is appropriate. There are however certain pitfalls that need to be kept in mind which, if the interventionalist is not careful, can adversely affect the outcome.

Carotid stent migration was found four days post-procedure on the right side and one day post-procedure on the left side on angiography and duplex ultrasound, respectively. This is the first reported case of bilateral carotid artery stenting complicated by bilateral proximal migration of open-cell design stents in the early post-procedure period.

Studies have suggested that recently approved stent retrievers are safer and more effective than earlier-generation thrombectomy devices.

It has been shown to offer benefits such as decreased blood loss and "softening of the tumor" during subsequent resection. However, the actual benefits remain unclear, and the potential harm of an additional procedure along with the cost of embolization have limited its use to a small proportion of the meningiomas treated.

Onyx is an ethylene vinyl alcohol copolymer dissolved in dimethyl sulfoxide that is approved for use as an embolic agent for brain AVMs.
Case Report: We describe a case of revascularization of an occluded vertebro-basilar artery during embolization of an AVM with Onyx, by using the Merci device.

Objective: Cerebral venous thrombosis is often associated with nonspecific clinical complaints. In addition, the imaging findings are often subtle. Underdiagnosis or misdiagnosis of cerebral venous thrombosis can lead to severe consequences, including hemorrhagic infarction and death.
