Extradural venous haematoma

Case contributed by A.Prof Frank Gaillard


Fall onto hard surface. Headache.

Patient Data

Age: 30 years

Overlying the parietal bone towards the vertex immediately underneath the parietal bone, there is an area of extra-axial hyperdensity, which is best appreciated on the sagittal reconstructions. There is adjacent subgaleal haematoma overlying this extending posteriorly towards the parieto-occipital bone, but no underlying fracture is seen. There is compression and displacement of the adjacent superior sagittal sinus due to its mass effect. 


Appearances are characteristic of a venous epidural hematoma


MRI 4 weeks later

MRI one month later demonstrates a persisting subdural haematoma. The previously demonstrated venous extradural haematoma has resolved. 

Case Discussion

The rule of "extradural haematomas shall not cross suture lines" is only valid if the sutures are intact. Even a diastasis which is difficult to appreciate can tear the parietal dura and allow for extradural venous haemorrhage.
