Neuroimaging findings in rare amebic infections of the central nervous system.

The imaging findings in a case of panamebic meningoencephalitis and in a case of granulomatous amebic encephalitis, two rare infections of the central nervous system caused by amebae, are presented and the world literature is reviewed. The brain CT findings in panamebic meningoencephalitis are nonspecific; our case showed diffuse edema. In the case of granulomatous amebic encephalitis, there was evidence of large arterial occlusions and MR demonstration of spinal cord infarctions.
