TL;DR
The case of an adult patient with a focus of meningioencephalitis in whom the earliest magnetic resonance imaging (MRI) manifestation was hyperintense signal on diffusion-weighted sequence only is reported.
Abstract
We report the case of an adult patient with a focus of meningioencephalitis in whom the earliest magnetic resonance imaging (MRI) manifestation was hyperintense signal on diffusion-weighted (DW) sequence only. To our knowledge, this is the first adult encephalitis case to be reported with the MRI diffusion-weighted pulse sequence being the only positive MRI finding. A brief review of the pertinent literature is included.

This article examines the diagnostic ability of diffusion-weighted imaging to discriminate brain abscess from necrotic or cystic tumors and finds high signal intensity was observed in the abscess fluid, associated with low ADC.

In nine of the 13 patients examined, diffusion-weighted imaging was superior to other diagnostic imaging sequences (fluid-attenuated inversion-recovery sequences in eight patients and a T2- Weighted spin-echo sequence in one patient).

By varying slice-selective gradients in successive data acquisitions, the first in vitro measurements of molecular self-diffusion coefficients were performed in a magnetic resonance imager at 0.35 Tesla, adding T1, T2, mobile proton density, flow velocity, magnetic susceptibility, and chemical shift to the list of biophysical parameters measurable by magnetic resonance imaging in the noninvasive characterization of biological systems.

Diffusion imaging appears to be a promising sequence to monitor the changes in the brain tissue in herpes encephalitis, and in other infections as well with respect to restriction of movement or relatively high-motion of water molecules, providing data on the severity of the disease.

Investigating the role of diffusion imaging in central nervous system infections in pediatric patients found it more sensitive than conventional MRI alone in detection of changes due to infections and ischemic lesions, but did not differentiate between them by DI or apparent diffusion coefficient (ADC), although anatomic distribution of lesions proved useful.

Examination of brain tissue metabolism in acute demyelinating encephalitis by serial MRI including diffusion‐ and perfusion‐weighted imaging (DWI, PWI) suggests combining standard MRI with DWI and PWI may elucidate different overlapping phases in cerebral inflammation.

Fast FLAIR images showed pathologic changes in intracranial infectious diseases better than or as well as conventional T2- and proton density-weighted spin-echo sequences, however, postcontrast T1-weighting spin- echo sequences resulted in better visibility of abscess, meningitis, cysticercosis, and epidural empyema than did FLair images.
