According to some theories, obstruction of CSF flow produces a pressure drop in
the subarachnoid space in accordance with the Bernoulli theorem that explains
the development of syringomyelia below the obstruction. However, Bernoulli's
principle applies to inviscid stationary flow unlike CSF flow. Therefore, we
performed a series of computational experiments to investigate the relationship
between ... hiện toàn bộ

Magnetic resonance imaging (MRI) is the imaging modality of choice for the
evaluation of the brachial plexus due to its superior soft tissue resolution and
multiplanar capabilities. The evaluation of the brachial plexus however
represents a diagnostic challenge for the clinician and the radiologist. The
imaging assessment of the brachial plexus, in particular, has been traditionally
challenging du... hiện toàn bộ

Tuberous sclerosis complex (TSC) is an autosomal dominant multisystem disorder
which affects the skin, brain, heart and other organs. It is caused by mutations
of two genes: TSC1 (on chromosome 9q34) or TSC2 (on 16p13.3). 70% of cases are
sporadic with new mutations. This study aimed to highlight the utility of
prenatal MRI as an adjunct imaging modality in the diagnosis and prognosis of
tuberous ... hiện toàn bộ
Vein of Galen aneurysmal dilatation is generally considered an abnormal
deep-seated arteriovenous shunt that drains into the Vein of Galen. We herein
present three pediatric cases of vein of Galen aneurysmal dilatation (VGAD). The
locations of these shunts are anatomically different from just parenchymal as
previously reported, but are also cisternal and intraventricular. Clinical
symptoms, neuror... hiện toàn bộ

We used continuous electroencephalography-functional magnetic resonance imaging
(EEG-fMRI) to identify the linkage between the “epileptogenic” and the
“irritative” area in a patient with symptomatic epilepsy (cavernoma, previously
diagnosed and surgically treated), i.e. a patient with a well known
“epileptogenic area”, and to increase the possibility of a non invasive
pre-surgical evaluation of dr... hiện toàn bộ
Objective The conventional arteriovenous malformation (AVM) Onyx embolization
technique is the extrusion Onyx injection technique, with blood-flow control
after a certain distance casting through the head end of the microcatheter. This
method has elevated periprocedural AVM bleeding complications. In this study,
the authors reported safety and efficacy of an updated ante-grade drifting Onyx
inject... hiện toàn bộ
Spinal cord infarcts have been reported in young healthy patients following
contact with the water on the beaches of North Carolina. Although their exact
cause is not known, contact with a toxic marine animal has been proposed. We
describe a patient who suffered a “seastroke” and review the pertinent
literature.
