Copyright policy )Neuroimaging Abnormalities with Hypoqlossal Nerve Palsies
AbstractSeven patients with acute or chronic unilateral hypoglossal nerve lesions were evaluated by magnetic resonance imaging and computed tomography. In patients with acute to subacute tongue paralysis, the base of the ipsilateral side of the tongue appeared expanded and showed increased signal intensity on T2‐weighted images. This appearance was suggestive of an infiltrative mass lesion within the tongue. These radiographic findings are due to the pathophysiological process of nerve injury and muscle denervation.
