with fever and right facial tenderness. Axial CT with contrast of the brain with bone windows (left) shows complete opacification of the mastoid air cells bilaterally. MRV with contrast of the brain (right) shows a lack of venous flow in the right sigmoid sinus.The diagnosis was acute mastoiditis with thrombosis of the right sigmoid sinus.
Dural sinus occlusive disease (DSOD) is an infective form of dural sinus thrombosis (thrombophlebitis) commonly seen in the setting of acute otomastoiditis. It typically presents with:
- severe headaches
- high fevers
- sixth nerve palsy - due to involvement of Dorello's canal
- altered conscious state
The diagnosis can be difficult to make, even with MRI, due to the frequent artifacts of flow, and the enhancement of the thickened dura mater and also potentially of the clot itself. However, the demonstration of normal flow in the dural venous sinus essentially excludes the diagnosis.
