Delayed Leukoencephalopathy: Three Case Reports and a Literature Review

Background: Delayed leukoencephalopathy (DL) is a rare entity associated with cerebral hypoxia and heroin consumption. We describe the clinical course of three cases of DL due to non-heroin drug use. Material and methods: We describe the cases of three DL patients admitted to our hospital in 2012. Discussion: These cases contribute to the aetiological spectrum of DL since multifactorial causes could account for the clinical symptoms.
