Rocky Mountain spotted fever: 'starry sky' appearance with diffusion-weighted imaging in a child

Pediatr Radiol. 2012 Apr;42(4):499-502. doi: 10.1007/s00247-011-2209-x. Epub 2011 Sep 1.


We present a case of Rocky Mountain spotted fever encephalitis in a child imaged utilizing diffusion-weighted MRI. Although the imaging and clinical manifestations of this entity have been previously described, a review of the literature did not reveal any such cases reported in children utilizing diffusion-weighted imaging. The imaging findings and clinical history are presented as well as a brief review of this disease.
