Neuroradiol.1988 Sep 01; 9 AB - Three children were examined who had surgery to remove gangliocytomas in order to control seizures that were refractory to medical therapy. The CT characteristics of gangliocytomas are those of a hyperdense lesion that does not demonstrate contrast enhancement. The MR findings show a region of mixed signal intensity on T1-weighted and proton-density images, and decreased signal intensity on T2-weighted images. Little mass effect, if any, is seen with these lesions.
