Seven of eight patients with magnetic resonance imaging of the spinal cord had nonenhancing lesions of the gray matter of the spinal cord spanning multiple levels, and seven of nine with magnetic resonance imaging of the brain had nonenhancing brainstem lesions (most commonly the dorsal pons).
Most patients presented with acute focal limb weakness and their MRls showed nonenhancing lesions that were largely restricted to the gray matter and spanned more than the level of the spinal cord in most of the cases.
Magnetic resonance imaging of the brain showed multiple nonenhancing lesions that were suggestive of PML (Figure).
Differentiating enhancing vs nonenhancing lesions in the liver and kidney: comparison of single- and dual-energy CT.
On MRI, nasal gliomas are nonenhancing lesions within the nose or anterior to the nasofrontal suture (actually extranasal) or nasal septum that are T1 isointense and slightly T2 hyperintense (secondary to gliosis), relative to brain parenchyma.
The MR imaging appearance is one of asymmetric, T2-hyperintense, nonenhancing lesions within the periventricular and subcortical WM of the cerebral hemispheres (Figure 16).
