Patient 8. Patient 8. A, Follow-up at day 15. MSE is still identified in the thrombosed vein. B, A hyperintense spot is present in the lumen of a cortical vein on the T1-weighted image (arrow), appearing as a flow void on the initial T1-weighted image (Fig 4B, arrow). C−E, On coronal images in the same plane, the aspect of a cord sign is visualized at the surface of the cortex, hyperintense on T1- and T2-weighted images (arrow, C and D) and hypointense on the T2*GE image (E). The underlying hematoma is well identified on T1- and T2*GE images. M. Boukobza et al. AJNR Am J Neuroradiol 2009;30:344-348 ©2009 by American Society of Neuroradiology
