BACKGROUND Pathophysiological basis of Magnetisation Transfer Ratio (MTR) reduction in multiple sclerosis still remains a matter of controversy. Optic nerve represents an ideal model to study the consequences of axonal loss and demyelination on MTR since effects of disease on the optic nerve are clinically apparent and potentially quantifiable by objective(More)
OBJECTIVE The purpose of this case study is to describe the case of a person with agenesis of the corpus callosum (ACC), intellectual disability and features of antisocial behaviour and lying. METHODS A 26-year-old woman with a mild intellectual disability who presented with antisocial behaviour and chronic lying was found to have ACC and associated(More)
Lasting taste disturbance has been previously reported as a consequence of brainstem infarction, but there are no previous reports of transient gustatory sensations preceding the onset of stroke. Ophthalmodynia, presenting as "salt-and-pepper" eye pain, has been reported rarely. We present a 58-year-old right-handed woman who had fluctuating ophthalmodynia(More)
We report the case of a 57-year-old man who sustained an isolated severe traumatic brain injury (TBI). During his admission to the intensive care unit (ICU), he developed marked arterial hypotension of unclear cause. Eventually, the presence of renal angle tenderness on clinical examination and a low random-cortisol level lead to the suspicion of primary(More)
Conventional magnetic resonance imaging (MRI) is the technique of choice for diagnosis of cerebral tumours, and has become an increasingly powerful tool for their evaluation; however, the diagnosis of common contrast-enhancing lesions can be challenging, as it is sometimes impossible to differentiate them using conventional imaging. Histopathological(More)
We present two cases of recurrent progressive multifocal leukoencephalopathy (PML) in patients with long standing virally suppressed human immunodeficiency virus (HIV) and normal CD4+ T cell count who were taking stable regimens of highly active antiretroviral therapy (HAART). This has significant implications for other patients with a past history of PML,(More)
BACKGROUND Ulnar neuropathy at the elbow (UNE) is the second most common mononeuropathy of the upper extremity. One rare cause of UNE is nerve mass lesions, including intraneural ganglion cysts (IGCs). IGC imaging studies provide important information that may determine the nature of a peripheral nerve mass lesion. CASE DESCRIPTION We present the case of(More)
We report a patient with a large infratentorial neurenteric (NE) cyst. Intracranial NE cysts, also known as enterogenous cysts, constitute a rare, generally benign entity of unknown aetiology. The presentation, imaging characteristics and management of the case is discussed, including illustrative peri-operative images.
Ophthalmic manifestations of allergic fungal sinusitis (AFS) are rare, but can occur in advanced disease. A 32-year-old man with advanced AFS presented with severe bilateral vision loss and restricted ocular motility. Magnetic resonance imaging and histological analysis confirmed active chronic AFS. Functional endoscopic sinus surgery was performed, with(More)
