Histoplasmosis brain abscesses in an immunocompetent adult. A case report and literature review.

We describe the case of a 62-year-old man, who presented with a new onset of focal seizures of his right leg. There were no other clinical symptoms, and laboratory results were normal. Brain magnetic resonance imaging revealed multiple lesions, two supratentorial lesions were ring-enhancing.

Comparing the volume of gliomas in the brain in FLAIR and post-contrast T1-weighted MRI sequences.

The imaging modality used to diagnose and monitor brain gliomas is magnetic resonance imaging (MRI), with standard protocols including contrast-enhanced T1-weighted and fluid-attenuated inversion recovery (FLAIR) image sequences. Many clinical trials are currently using contrast-enhanced T1-weighted MR image sequences to evaluate tumor response to treatment, but it is our hypothesis that FLAIR sequences will detect higher tumor volumes and, therefore, should be the preferred image sequence for this purpose. In this retrospective study, a volumetric analysis was conducted on the post-contrast T1-weighted and FLAIR MR image sequences of 38 patients with confirmed brain gliomas.

Volumetric Examination of MS Plaques and Correlation with EDSS Ratings.

This study is a retrospective analysis of 17 patients with multiple sclerosis. The total volume of plaques from three different MR image sets of the brain was correlated with the EDSS ratings of the patients. Each of the correlations showed a positive relationship, but none was statistically significant.
