From: Case report: a case of primary intracranial parasagittal meningeal angiosarcoma
A Admission CT showed bilateral parasagittal high-density lesions, mainly on the left side, located in front of the motor area of the brain. B T1-weighted images and (C) T2-weighted image showed a parasagittal mass with irregular mixed signals, and some speckle high-signals was seen in it. D T2-FLAIR image showed mixed signals with ill-defined borders, encompassing the superior sagittal sinus, and invading the adjacent skull. E Axial T1-weighted images with contrast enhancement. F Sagittal T1-weighted image with contrast enhancement, showed uneven and obvious enhancement of the lesion, involving bilateral parasagittal dura and sagittal sinus, and local brain tissue compression
