To describe a case of successful intracranial angioplasty and stenting of a symptomatic middle cerebral artery (MCA) stenosis using a transcervical approach. ⋯ Access of the intracranial circulation through direct CCA puncture may be a feasible alternative when the transfemoral access is not possible. The transcervical approach may be safe even with the use of antiplatelet medications and anticoagulation.

We investigated how many contrast-transcranial Doppler (c-TCD) examinations should be performed on different days in patients with acute stroke. ⋯ c-TCD examinations should be performed on at least two different days to assess the prevalence of RLS.
-
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.

Case Reports
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.
