'Wine Glass' appearance: a unique MRI observation in a case of primary lateral sclerosis.

ABSTRACT

Magnetic resonance images (MRI) in a patient with primary lateral sclerosis is described. T2WI, MRI of brain showed characteristic hyperintensities of the corticospinal tracts bilaterally, extending from the internal capsule to the brain stem - producing a 'wine glass' appearance on coronal sections, which has not been described so far to the best of our knowledge. Differential diagnosis of this interesting 'wine glass' appearance on MRI along with a review of the MR-signal abnormalities in motor neuron disease is discussed.
