FIG 6. A–D, Large pacchionian granulation at the top of the straight sinus (arrowheads). Pacchionian granulation is hypointense on reconstructed sagittal and source axial images (A and B) of 3D contrast-enhanced MP-RAGE (13.5/7/1, TI = 300, flip angle = 15°) and hyperintense on T2-weighted image (C) (3700/96/1). DSA image (D) shows filling defect in corresponding region (and could be misdiagnosed as a sinus thrombus)
