Computed tomographic brain scan findings in Q fever encephalitis.

Neurological involvement in Q Fever is unusual. We present a case of encephalitis due to Coxiella Burnetii with neuroradiologic findings on CT not described previously, consisting in areas of decreased absorption coefficient in the subcortical white matter of both hemispheres, predominantly in the right. Differential diagnosis must be established from viral encephalitis, of similar clinical presentation, which may show similar CT lesions to those in this case.
