Acute disseminated encephalomyelitis(ADEM) is an uncommon acute inflammatory disease of the CNS which follows viral infections or Vaccination. ADEM is thought to be an immune mediated disease. The classic featues of ADEM include an antecedent event, commonly a viral illness, followed after a latent period by acute onset of multifocal or diffuse CNS signs, the potential for extensive or even complete recovery, and pathologic evidence of perivascular inflammation and demyelination. We experienced a 43-year-old patient with ADEM and reviewed literatures.

Multiple cardiac myxomas are rare in children. However, myxomas may be lethal because of their various manifestations such as blood flow obstruction, embolization and constitutional changes. Especially, the cerebral infarction due to tumor fragmentation are more likely to be misdiagnosed of acute disseminated encephalomyelitis. We report a case of multiple cardiac myxoma complicating recurrent right hemiparesis in a 12-year-old child who at first had a wrong diagnosis of acute disseminated encephalomyelitis (ADEM). Consequently, a child who show unrepresentative symptom of ADEM, should be examined rapidly by various tools to rule out the cerebral infarction from cardiogenic cause.

Acute disseminated encephalomyelitis(ADEM) and acute relapsing disseminated encephalomyelitis(ARDEM) are representative demyelination diseases that occur among young children with a fulminant onset similar to encephalitis or meningitis. The diseases often occur after some viral infection of immunization and the etiology of these diseases is considered to be an autoimmune response because of the similarity in pathologic findings to experimental allergic encephalomyelitis. Cerebral computed tomography(CT) findings of demyelination in ADEM or ARDEM show normal to low density areas in the white matter. In cerebral MRI findings, a scattered distinct high intensity lesion considered to be demyelination is observed in 72-weighted imaging even in the early stages. ADEM is usually monophasic, but recurrent episodes may occure. When ADEM is reccurent, the distinction from multiple sclerosis becomes difficult. We report here a case of acute relapsing disseminated encephalomyelitis(ARDEM) in a 9 years old male child who experence ADEM, 3 times.

We report 3 cases of recurrent acute disseminated encephalomyelitis (ADEM) known as multiphasic disseminated encephalomyelitis (MDEM). The 3 cases presented with fever, headache, neck stiffness, abdominal pain, seizure and decreased mentality as well as focal neurologic deficits, which showed relatively good steroid responsiveness. Brain MRI revealed variable sized, multifocal, subcortical white matter lesions with gray matter involvement. The CSF study showed mild pleocytosis with negative oligoclonal band.

Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating conditions, which is usually monophasic. Recurrent ADEM and multiphasic disseminated encephalomyelitis (MDEM) is much less characterized entity, and its differentiation from multiple sclerosis (MS) poses a diagnostic challenge. We report a case of multiphasic disseminated encephalomyelitis (MDEM). The patient had two episodes of paraparesis and other neurologic symptoms, which were separated by 2 months. The patient presented with fever, headache, mental change, lower extremity weakness, voiding difficulty as well as focal neurologic deficits, which showed good response on steroid and acyclovir. Brain MRI revealed variable sized, multifocal, subcortical white matter lesions with gray matter involvement, and spine MRI revealed high signal intensity from C3 to T9 spinal cord. The CSF study showed elevated protein count and negative oligoclonal band.
