(a) 12/26/08 MRI coronal T1 postgadolinium image demonstrates a dural-based mass along the falx with heterogeneous enhancement (arrow). (b) 12/26/08 MRI sagittal T1 post-gadolinium image demonstrates the mass along the falx and an enhancing focus in the suprasellar cistern (arrows). (c) 4/8/09 MRI coronal T1 post-gadolinium image shows resolution of the previously identified enhancing mass within the falx. An Ommaya reservoir has been placed in the interim. (d) 4/8/09 MRI sagittal T1 post-gadolinium image shows resolution of previously seen enhancing anterior falx and resolution of the suprasellar mass.
