Neuroendovascular therapy is now the choice for the management of many neurovascular pathologies, and physicians with endovascular skills are in high demand. In addition to the traditional method of practicing hand movements to learn skills, a new strategy of practicing eye movements to learn skills is also attracting attention. This preliminary study explored the differences in gaze behavior depending on experience with endovascular procedures to be facilitated in future skill training in neuroendovascular therapy.

Four physicians with experience of 3-412 neuroendovascular procedures wore eye-tracking devices during coil embolization of swine cervical arteries. Gaze metrics with direct correlations to the expertise of endovascular procedures were explored.

Gaze metrics with a positive direct correlation to experience included the proportion of fixation durations (PFD) in the screen area and the native images. Those with a negative direct correlation included the PFD in the off-screen area and the roadmap images and the average fixation durations in the off-screen and coil areas. During the parent artery occlusion procedure with detachable coils, more experienced operators preferred to look at native images rather than roadmap images and that less experienced operators tended to look down at their hands more frequently.

This preliminary study demonstrated the feasibility of eye tracking to identify the differences in gaze behavior depending on the experience of endovascular procedures and may guide future eye-tracking studies in neuroendovascular therapy.

In resource challenged environments, the standard treatment of chronic subdural hematoma (CSDH) in the theater may be delayed because of the endemic financial constraint and logistic problems with consequent negative impact on the outcome. An emergency bedside burr hole craniostomy with a local anesthetic at the accident and emergency ward may be lifesaving in patients presenting in extreme neurological conditions in these settings.

We presented three patients (one male and two females) with CSDH who presented at our service in poor neurological condition. The patients were between 49 and 70 years. The Glasgow Coma Score ranged from 3 to 6. The three patients had respiratory and pupillary abnormalities at presentation. They all had bedside single frontal burr hole craniostomy drainage of the hematoma under local anesthesia at the accident and emergency unit of the hospital. Surgery was done within 1 h of review by the neurosurgical team in all cases. The duration of hospital stay ranged from 8 to 24 days. The outcome was good in all cases.

Bedside single burr hole craniostomy at the accident and emergency unit may be lifesaving in patients with CSDH who present in extreme neurological condition but in whom prompt standard surgical treatment in the theater is not feasible.

Because the neurological presentation of spinal epidural hematomas (SEH) is often not specific, they may be misdiagnosed as acute lumbar disk herniations. Epicatechin Here, we present a case in which a traumatic disc extrusion mimicked an epidural hematoma and reviewed the appropriate literature.

A 27-year-old male sustained a high-energy fall. The lumbar MRI scan showed a L4-S1 ventral medium/high signal intensity mass on the T1- and high signal intensity lesion on T2-weighted images; the original diagnosis was spinal epidural hematoma. However, at surgery, consisting of a left L4 and L5 hemilaminectomy with L4-L5 and L5-S1 laminotomy, an extruded lumbar disc was encountered at the L4-L5 level and removed; no additional pathology or SEH was found at either level.

On MR, SEH may mimic acute lumbar disk herniations. Depending on the clinical symptoms/signs, surgical intervention will both correctly confirm the diagnosis and relieve neural compression.

Squamous cell carcinoma (SCC) is the most common form of nonmelanoma skin cancer after basal cell carcinoma. Simple excision can be the treatment at early stages of diagnosis. However, at late stages, treatment is more complex due to extension to the skull and the dura. In extremely rare cases, it can invade the brain making it a challenging situation for treatment.

We present the case of a 54-year-old man with a history of cutaneous SCC who presented an invasive left frontal recurrence with brain invasion 19 years after initial surgery. The patient underwent surgery which consisted in tumor removal and bone and skin reconstruction. Immediate and late outcomes were favorable.

Multidisciplinary treatment for SCC diagnosed in advanced stages is the best way to obtain encouraging results. Although significant advancements have been made, further study is needed for cases with advanced disease.

Monostotic fibrous dysplasia rarely involves the lumbar spine. Although its optimal surgical management is unknown, some recommend complete resection to decrease the likelihood of future recurrence.

A 41-year-old female presented with fibrous dysplasia involving the right L4 lamina and spinous process. Following image-guided
resection, the patient remained asymptomatic without evidence of recurrence 8 months later.

Image-guided excision of monostotic fibrous dysplasia involving the right L4 lamina and spinous process was successfully performed without clinical or radiographic evidence of recurrence within 8 postoperative months.
