Rapid Spontaneous Resolution of Acute Cranial Subdural Hematomas - Two Case Reports

Abstract

Background: Acute cranial subdural hematoma (SDH) commonly occurs after traumatic brain injuries. Although, the vast majority of acute SDHs larger than 10 mm in thickness require immediate surgical evacuation, in rare occasions spontaneous resolution may occur. Two important mechanisms explained for this phenomenon are blood push out and blood wash out.

Case Presentation: In this article, we discuss two cases of spontaneous resolution of acute cranial SDH in addition to the proposed theories explaining this phenomenon. Furthermore, clinical parameters and imaging characteristics that might predict such phenomenon, are also reviewed.

Conclusion: It is possible to consider conservative management with ICU case for such patients if clinical and paraclinical criteria supports this decision.
