Value of susceptibility-weighted imaging in acute hemorrhagic leukoencephalitis.

Acute hemorrhagic leukoencephalitis (AHL) is a rapidly progressive disease in the spectrum of acute disseminated encephalomyelitis. Timely accurate diagnosis is crucial but challenging clinically and radiologically. However, imaging findings of AHL are quite specific when susceptibility-weighted imaging is utilized. The purpose of this report is to present the imaging findings of autopsy-proven AHL and thus to facilitate rapid recognition and treatment.
