Preoperative (top) axial, coronal, and sagittal T1 magnetic resonance (MR) with contrast demonstrating an enhancing epidural mass extending through the calvarium and into the subgaleal space with compression of the superior sagittal sinus (SSS). Postoperative (bottom) axial, coronal, and sagittal T1 MR with contrast showing gross total resection of tumor with preservation of the SSS and resolution of sinus stenosis

A biparietal craniectomy was performed with gross total resection of the mass as demonstrated in preoperative and postoperative MRI scans [Figure 1].
