Acute haemorrhagic encephalomyelitis (AHEM): MRI findings.

摘要: Acute disseminated encephalomyelitis (ADEM) comprises a group of demyelinating disorders the CNS, which haemorrhagic variant indicates most severe clinical course (AHEM). It is supposed to be caused by an overshooting immunological response following infection or vaccination. Restricted diffusion protons could demonstrated using DW-MRI in case rapidly progressive disease with additional haemorrhage. Hence, addition DWI adds diagnostic power MRI setting post-infectious CNS.
