Callen MS-ADEM criteria

Last revised by Henry Knipe on 12 Mar 2024

The Callen MS-ADEM criteria can be useful in differentiating between acute disseminated encephalomyelitis (ADEM) and multiple sclerosis (MS) in children, as the first attack of immune-mediated demyelination is a frequent diagnostic challenge.

Usage

The Callen MS-ADEM criteria compare well against several other diagnostic criteria (e.g. KIDMUS criteria, IPMSSG criteria) and perform better than others (e.g. Barkhof criteria, McDonald 2017, MAGMINS) 2,3.

Criteria

The criteria can only be applied to distinguish children with the clinical presentation of ADEM from that of a first MS attack. At least two out of the three following criteria should be fulfilled for MS diagnosis 1:

  • absence of a diffuse bilateral lesion pattern

  • presence of black holes

  • two periventricular lesions ​
