Review of imaging modalities and radiological findings of calvarial lesions

Figure 22  Intraosseous venous malformation in seventy-one years old female patient who underwent imaging for headache. A and B: Sagittal computed tomography on the bone window show a lytic lesion (arrows) in the left parietal bone, localized in the diploe region, causing widening of the inner table, in which bone trabeculae can be intensely selected; C: Three-dimensional computed tomography shows an intraosseous venous malformation (arrows) in the left parietal bone; D: The lesion is hyperintense (arrows) on axial T2-weighted image; E: On coronal fluid-attenuated inversion recovery T2-weighted image the lesion is hyperintense (arrows); F: On axial contrast enhanced T1-weighted image the lesion shows intense contrast enhancement (arrows).
