Doorto-computed tomography (CT) interpretation should be <45 min. Door to treatment should be <60 min. In our institution, we reached a door-to-treatment time as short as 20 min. Methods: On February 8, 2018, the first stroke code was activated in King Hamad University Hospital in Bahrain; to date, 565 stroke codes were activated. For patients presenting with acute neurological deficit to the emergency department, a total of 66 (11.7) patients were treated with revascularization therapy; patients were treated with only intravenous thrombolysis (34, 6.02%), only mechanical thrombectomy (17, 3%), or both (15, 2.65%). Results: In our institution, we reached a door-totreatment time as short as 20 min. Conclusion: In our program, time management is an important factor of success in the management acute cerebrovascular stroke.

They differ from arteriovenous malformations (AVMs) in that they involve single or multiple feeding arteries, draining directly into a dilated cortical vein with no intervening nidus. Pial and dural AVFs differ in blood supply, as the first originate from pial or cortical arteries and the latter from outside the dural leaflets. Unlike dural AVFs, most of the pial AVFs are supratentorial. The vast majority are congenital, manifesting during infancy. Acquired pial AVFs are significantly rarer and occur after vasculopathy, head trauma, brain surgery, or cerebral vein thrombosis. We describe a unique case of an acquired pial AVF in a 50-year-old man secondary to a cortical vein thrombosis manifesting as a focal-onset seizure with secondary generalization. A cerebral digital subtraction angiography revealed a low-flow pial AVF fed by a postcentral branch of the left middle cerebral artery draining to the superior sa...

Il constitue un element de morphologie complexe ayant plusieurs rapports intimes avec les differentes structures avoisinantes. Les progres techniques, notamment de l’imagerie par resonance magnetique (IRM) a totalement change l’approche diagnostique de la pathologie du corps calleux et a permis d’en modifier la prise en charge et le suivi. Les causes d’anomalie de signal du corps calleux sont dominees par les pathologies demyelinisantes et vasculaires. Les autres causes d’atteinte du corps calleux peuvent etre de nature metabolique, traumatique, tumorale, toxique et des causes micellaires ont ete individualisees.

The disappointing results of the microsurgical approach in the treatment of CSM have led to the evaluation of a more conservative strategy, such as conformal radiotherapy (CR) and stereotactic radiosurgery (SRS). Here we report our experience with CR in the treatment of CSM, aiming to evaluate local control, clinical response and radiation-induced toxicity. Methods: A total of 18 patients with CSM, treated from 2011 to 2017, were retrospectively reviewed. Results: Patient median age was 59 years [31–74]. Clinical presentation included impaired vision, cranial nerve deficit, headache, ocular signs. Median tumour size was 35 mm [13–56]. Six patients were operated before the radiation. Twelve patients were treated with definitive radiotherapy. Dose of radiation varied from 50.4 Gy in 28 fractions, to 54 Gy in 30 fractions. Median follow-up was 33 months [6–84]...

Its diagnosis and evaluation require a visual assessment in brain magnetic resonance images. This neurological disease is characterized by its unpredictable evolution. The most common form is relapsing–remitting multiple sclerosis, consisting of episodes of neurological dysfunction remitting with a variable degree of recovery. The underlying mechanisms are still unknown and have no mathematical models to explain this spatial and temporal dissemination. The main objective of this paper is to propose an approach based on chaos theory to define the clinical characteristics for lesion progression, principally its evolution. Previous authors have explored the nervous system by accurately modeling their attractors in the phase space and reproducing a non-linear result. This remains to be compared with chaotic attributes. In this work, multiple sclerosis lesions are treated through modeling and calculating of their degree of evolu...

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. Case Description: 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. Conclusion: 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.
