Magnetic resonance imaging (MRI) and MR venography studies show hypoplastic rostral superior sagittal sinus (SSS). There is compensatory drainage through a pair of parasagittal superior frontal veins, which course on the brain's surface, parallel to the midline from the pole of the frontal lobe, and join the middle third of the SSS near the coronal suture.

Case Discussion

Hypoplastic rostral superior sagittal sinus (SSS) is an anatomical variation of the dural venous sinuses, which radiologists must know to avoid the mistaken diagnosis of dural venous sinus thrombosis 1-3
