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.

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.

A 33-year-old woman presented a chronic headache and sore throat on the right side of her body, continuous pulsatile tinnitus with decreasing hearing in the right ear, and recurrent bleeding from the right ear. Computer tomography and magnetic resonance imaging scan depicted a mass in the external ear canal and an enlarged right jugular bulb, which was revealed on duplex ultrasound in the upper portion of the right internal jugular vein. Surgical dissection of the tumor was performed. Pathological study revealed the mass was glomus jugulare tumor.

Hyperpneumatization of the temporal bone with extension into the occipital bone and even the parietal bones is a rare condition. We report a case in which the patient suffered periodically from a palpable mass in the parietal-occipital region which originated from extensive occipital bone pneumatization. Computed tomography examination revealed extensive temporal and occipital pneumatization and subperiosteal pneumatoceles, which was corrected by surgery.

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.
