Randomized Controlled Trial
Clinical-radiological severity mismatch phenomenon: patients with severe neurological deficits without matching infarction on computed tomographic scan.
The objective was to determine the long-term outcome of patients with severe persistent neurological deficits without a large infarction on computed tomographic (CT) scan. ⋯ We observed that approximately one-fourth of patients with severe neurological deficits have clinical-radiological severity mismatch. Such patients appear to have a high rate of favorable outcomes at 1 year.

To evaluate magnetic resonance imaging (MRI) features of ruptured spinal dermoid tumors with spread of lipid droplets in the central spinal canal and/or spinal subarachnoid space and to understand the underlying mechanism. ⋯ Spinal dermoid tumors ruptured into central spinal canal and/or spinal subarachnoid space have unique MRI features. The absorption of lipid droplets within central spinal canal is rather difficult, and their movement is extremely slow. We propose that fatty components within the central canal of spinal cord may be partially associated with spinal dermoid tumors developmentally.

Ischemic stroke is a common complication of cryptococcal meningitis. Fluid attenuated inversion recovery vascular hyperintensity (FVH) is a neuroimaging marker of sluggish blood flow usually seen in the setting of acute stroke. FVH have never been described in the setting of meningitis. ⋯ In conditions with high risk of stroke, such as meningitis, the presence of FVH should alert the clinician to the possibility of impending infarction.
