Neuroimaging "HINTS" of the Lateral Medullary Syndrome.

A series of neuroimaging studies illustrates many of the key findings of the lateral medullary syndrome.

Free Floating Thrombus in Carotid Artery in a Patient with Recurrent Strokes.

We present a case of 72-year-old male with reported past medical history of recurrent transient ischemic attacks (TIAs) presenting with myriad of neurological symptoms. Patient was transferred from outlying hospital with complaints of right sided facial droop and dysarthria. Computed tomography angiography (CTA) showed high grade proximal left internal carotid artery (ICA) stenosis along with interesting finding of a free floating thrombus (FFT) in the left ICA.

Magnetic resonance spectroscopy imaging characteristics of cerebral Blastomycosis.

Background: Blastomycosis is a dimorphic fungus that is endemic to the midwest and southwestern United States. Involvement of the central nervous system (CNS) is thought to only represent 5-10% of cases of disseminated Blastomycosis.

Case Description: A 54-year-old Caucasian female presented to the Neurosurgery service with a 1-day history of progressive right sided hemiparesis.

Cortical vision loss as a prominent feature of H1N1 encephalopathy.

A 20-year-old woman infected with the 2009 H1N1 strain of influenza A developed bilateral visual loss. Brain MRI showed restricted diffusion of the parietal and occipital lobes, and her spinal fluid did not contain inflammatory cells. This report describes an unusual case of H1N1 influenza A virus infection primarily affecting the posterior visual pathways.
