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.
