METHODS: The first patient presented to us after sustaining a fall with a GCS of 15/15 and a large parieto-occipital EDH with a volume of 90 cm3. He was treated non-operatively. Follow-up CT showed good resolution of the haematoma. The second patient presented with a GCS of 7/15, a posterior fossa EDH with a volume of 30 cm3, and obstructive hydrocephalus. Emergency ventriculostomy was performed, which was converted to a VP shunt. The third case was a patient presenting with a large hemispheric EDH, which was 130 cm3 in volume. The GCS at presentation was 14/15 but dropped to 6/15, following which he underwent craniotomy and evacuation of the EDH.
RESULTS: The Glasgow Outcome Scale (GOS) at three months was five for the first two cases and three for the third case with a dense right hemiplegia.
CONCLUSIONS: EDH, both supratentorial and in the posterior fossa, can be managed non-operatively. A large volume EDH (>30 cm3) can be managed non-operatively provided the GCS at presentation and follow up remains the same with symptomatic improvement. Prompt treatment of a large volume EDH may still result in a poor outcome.
