Fig. 1 A; Axial computed tomography scans indicate the extradural tumor compressing cerebral parenchyma in the right middle cranial fossa. There are bony outer shells and multiple internal septa (arrow). B-E; Preoperative magnetic resonance imaging showing the lesion. T1-weighted scans (B) depict expansile, extra-axial lesions in the right medial cranial fossa. T2-weighted scans (C) and T1-weighted MR images with contrast enhancement (D, axial image; E, coronal image) showed fluid-fluid interfaces within cystic lesions of the tumor. F; The right external carotid angiogram revealed the tumor blush through the right internal maxillary arteries.
