Actinomycotic brain infection: registered diffusion, perfusion MR imaging and MR spectroscopy

Sumei Wang et al. Neuroradiology. 2006 May.

Abstract

Introduction: Actinomycotic brain infection is caused by an organism of the Actinomyces genus. We report here one such case.

Methods: The methods used included coregistered diffusion, perfusion and spectroscopic magnetic resonance (MR) imaging.

Results: Decreased apparent diffusion coefficient, markedly elevated fractional anisotropy (FA) and reduced cerebral blood flow were observed. MR spectroscopy demonstrated elevated amino acids, acetate and succinate.

Conclusion: Elevated FA values may be due to the microstructure of this special brain infection.
