Background: The syndrome of oculopalatal tremor is a known consequence of lesions in the dentate-olivary pathway. Hypertrophic degeneration of the inferior olive is a recognized pathological correlate of these lesions and hypothesized to cause tremorogenic olivary hypersynchrony. However, oculopalatal tremor also occurs in Alexander disease, which produces severe inferior olive degeneration without intervening hypertrophy.

We report a case of pituitary hypophysitis and orbital inflammation followed by an orbital apex syndrome. A 64-year-old woman with a history of skin melanoma, receiving ipilimumab treatment, was seen for near total loss of vision in the right eye and proptosis.

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.

Advances in the radioimaging of neuro-ophthalmologic disorders may evolve from the clinical or the radiological side, meaning there is a constant stream of new information for the clinician.
Recent Findings: Functional MRI, diffusion tensor MRI, magnetization transfer imaging, and magnetic resonance spectroscopy are examples of nonstandard radiographic techniques, which have expanded the knowledge of neuro-ophthalmologic conditions.
This article discusses the imaging of infectious and other inflammatory conditions that affect the spinal cord, spinal column, intradural spinal nerve roots, and spinal meninges with emphasis on magnetic resonance (MR) imaging. Inflammatory lesions of the spine are often indistinguishable on imaging and even on pathologic examination. However, infectious causes are treatable so it is important for the radiologist to make the diagnosis.
