The authors present four cases of acute epidural hematoma (three supratentorial and one in the posterior fossa), in which non-operative treatment was performed. The conditions to undertake this treatment were: good clinical and neurological state of the patients on admission (GCS equal or more than 14), absence or mild focal symptoms and possibility to observe the patients and to perform CT follow-up. All patients had a good recovery. The authors discuss these cases and present the review of the literature concerning the problem.
