Abstract

We report a case of parasellar dermoid tumor with intra-tumoral hemorrhage. It is rare for a dermoid tumor that hemorrhage was detected as high attenuation on the initial CT. In the present case, the tumor content included a little fat component and mostly cholesterin-rich fluid which resulted in extremely low signal intensity on T2-weighted and high signal on T1-weighted MR images. In addition to this, hemosiderin accumulation in the tumor could be the reason for low signal intensity on T2-weighted images.
