To investigate the potential of the ultrasound-based evaluation of the optic nerve sheath in a patient with spontaneous intracranial hypotension due to cervical cerebrospinal fluid (CSF) leakage. ⋯ The ultrasound-based evaluation of the optic nerve sheath may be helpful in detecting CSF hypovolemia and for determination of treatment effects. This report should be seen as a basis for future investigations on the sonographic assessment of the optic nerve sheath in diagnosis and treatment of intracranial hypotension.

We describe a rare case of a patient with left frontotemporal gliosarcoma, which metastasized through the cerebrospinal fluid (CSF) to the leptomeninges and pachymeninges. Pathologically confirmed, magnetic resonance imaging-visible leptomeningeal spread of gliosarcoma via the CSF has not been previously reported.

A correlation between fractional anisotropy variations and clinical recovery in spinal cord infarctions.
To describe diffusion-weighted imaging and diffusion tensor imaging variations in spinal cord infarctions. ⋯ FA values could be an interesting prognosis marker in spinal cord ischemia, which needs to be confirmed by a larger study.

Orbital penetrating injuries may cause significant harm to optic nerves and eyeball as well as to the brain and cerebral vasculature. Defining surrounding neurovascular structures by CT angiography (CTA) is important for surgical removal. We present an uncommon case of a 3-year-old child with a penetrating orbital injury caused by a toothbrush. To the best of our knowledge, there is no report orbital injury with a toothbrush so far.

Presentation of an interrupted aortic arch (IAA) in adulthood is extremely rare. Nonhemorrhagic stroke has not been reported previously in any adult with IAA. We, herein, describe a formerly asymptomatic 52-year-old male presenting with recurrent vertebrobasilar circulation ischemic strokes resulting from accelerated atherosclerotic arteriopathy secondary to IAA associated upper body hypertension. Surgical correction of IAA led to treatment of hypertension and cessation of ischemic attacks together with regression of collateral arterial networks as shown by computer tomography angiography.
