Hypoplastic Superior sagittal sinus
Non contrast 2 D TOF MR Venogram:
Anterior portion of the SSS is hypoplastic, replaced by bilateral longitudinal frontal cortical veins which ultimately ending into rest of the superior sagittal sinus – a relatively uncommon anatomical variation, should not to be mistaken for thrombosis.
Note an associated hypoplastic left transverse sigmoid sinus.
