Does Vestibulo-Ocular Reflex (VOR) Gain Correlate With Radiological Findings in the Semi-Circular Canals in Patients Carrying the p.Pro51Ser (P51S) COCH Variant Causing DFNA9? Relationship Between the Three-Dimensional Video Head Impulse Test (vHIT) and MR/CT Imaging.

Objective: The primary aim was to determine whether 3D video-head-impulse-test vestibulo-ocular reflex (vHIT VOR)-gains correlate with computed tomography (CT) and magnetic resonance (MR) lesions in a series of carriers of the p.(Pro51Ser)-variant (P51S) in the COCH-gene (DFNA9). Secondary aim was to compare routine imaging with second peer review radiologic lecture.

Spinal cord herniation after brachial plexus injury.

Background: Spinal cord herniation (SCH) is an uncommon cause of myelopathy. Documented trauma is a rare cause, and most cases are idiopathic. One special type of trauma that may lead to SCH is a brachial plexus injury.

Imaging in Myotonic Dystrophy Type 1 - Case Reports.

Myotonic dystrophy type 1 (DM1) is the most common of the muscular dystrophies. It is an autosomal dominant neuromuscular disorder with multisystem involvement, including the central nervous system. Two DNA-proven cases are presented.

Focal sclerosis of semicircular canals with severe DFNA9 hearing impairment caused by a P51S COCH-mutation: is there a link?

Hypothesis: Focal sclerosis of one or more semicircular canals on computed tomographic (CT) scans and a corresponding signal loss on magnetic resonance (MR) imaging are radiologic lesions that are linked to patients who are suffering from advanced otovestibular impairment caused by hereditary DFNA9 hearing loss.

Background: DFNA9 is a hereditary hearing loss that is characterized by late-onset progressive imbalance and hearing deterioration, caused by mutations in the COCH gene. To date, no radiologic lesions have been associated with this condition.

Gadolinium-enhanced angiography for diagnosis and interventional treatment of subclavian artery stenosis prior to fistula creation.

We report the use of gadolinium-based contrast agent for both diagnostic and interventional subclavian angiography in two azotemic patients, presenting with an asymptomatic, high-grade stenosis of the left subclavian artery, ipsilateral to the site of choice for native fistula creation. Angiographic imaging performed with diluted gadolinium-based contrast material was clear enough to perform successful subclavian artery stenting, resulting in normalization of the arterial blood pressure in the afferent artery of the dialysis fistula. Clinically, no decrease in residual renal function and no other complication were noted immediately or a longer period after the interventional treatment.
