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.
我们报告两例经手术证实的胶样囊肿病例,其在CT扫描上比在磁共振成像(MR)图像上更明显。这些囊肿在CT扫描上呈高密度,但在多个MR序列上与脑实质几乎等信号。这种相对不明显的表现对于头痛患者进行成像时是一个潜在的陷阱。
