Acute disseminated encephalomyelitis: a report of six cases.
Six children with Acute Disseminated Encephalomyelitis (ADEM) were seen at the Penang Hospital over a two year period (July 1999-June 2001). Diagnosis was based upon typical clinical features and characteristic findings on neuroimaging. Cerebrospinal fluid examination and other investigations were done, where appropriate, to rule out other causes of central nervous system disease. Three children had a prodromal illness. The most common presenting symptoms were fever, seizures, ataxia, focal neurological deficits and labile mood. Two children presented with status epilepticus. All children had an abnormal neurological examination. Brain magnetic resonance imaging revealed hyperintense signals on T2-weighted and FLAIR sequences in the subcortical and deep white matter regions of the frontal, parietal, and temporal lobes, as well as in the thalami, cerebellum and brainstem. One child had multiphasic disseminated encephalomyelitis (three episodes). The child with multiphasic disease had only one treated episode, and has suffered mild disability. Three children were treated with either methylprednisolone or immunoglobulins, and remain well. One child received both treatments but expired as a result of severe gastrointestinal bleeding from the use of methylprednisolone. The child who was not treated has severe disability.
