The axial contrast-enhanced magnetic resonance images (Figure 1) revealed a lack of enhancement in the distal left transverse sinus owing to a nonenhancing fresh clot. The dural enhancement around the left tentorium was abnormal, likely because of altered venous drainage. Reformatted magnetic resonance venography sequences (Figure 2) also demonstrated thrombosis throughout the left transverse sinus and the sigmoid sinus and allowed visualization of portions of the internal jugular vein. The rest of the dural venous sinuses were widely patent and normal in appearance.
