TY - JOUR T1 - Colloid cyst of the third ventricle: sometimes more conspicuous on CT than MR. JF - American Journal of Neuroradiology JO - Am. J. Neuroradiol. SP - 875 LP - 878 VL - 19 IS - 5 AU - A C Mamourian AU - L D Cromwell AU - R E Harbaugh Y1 - 1998/05/01 UR - http://www.ajnr.org/content/19/5/875.abstract N2 - We present two cases of surgically proved colloid cysts that were more apparent on CT scans than on MR images. These cysts, while hyperdense on CT scans, were nearly isointense with brain on multiple MR sequences. This relative lack of visibility represents a potential pitfall when imaging a patient with headache. ER -
