Sagittal T2W (a) and coronal T2W images demonstrated right pariental complex fluid collection with internal septation (blue arrow) and different internal hemorrhagic stages and mass effect (b). Axial FLAIR image demonstrated that collection over right temporoparietal extraaxial collection with mass effect has focal internal layering (c). Contrast-enhanced T1W image showed diffuse nodular dural thickening and dural enhancement (orange arrow) (d).
