PMLVs along the SSS. White arrows denote the location of signal intensity on the Pre-contrast FLAIR sequence (second column), located adjacent to the SSS when localized on the anatomic T1w MP2RAGE sequence (first column). White arrows on subtraction images (d-FLAIR 1 and d-FLAIR2) denote where gadolinium accumulation signal is present. SSS M, L, R are along the sinus anterior to the coronal suture. SSS Plexus is along the sinus posteriorly. The fixed enhancement signal pattern is illustrated at SSS L, SSS R, and SSS Plexus. SSS M, L, R = Superior sagittal sinus median, left, and right, respectively. SSS Plexus = Superior sagittal sinus plexus.
