Acute disseminated encephalomyelitis, an inflammatory and demyelinating disorder of central nervous system white matter, typically occurs following childhood viral infections. Although CT may demonstrate abnormalities, many children have normal CT studies in spite of widespread neurologic abnormalities. We report a series of five patients with the typical clinical presentation of disseminated encephalomyelitis who were studied using magnetic resonance imaging (MRI). In each case the children presented with progressive subacute neurologic abnormalities including headache, diplopia, ataxia, hemiparesis, seizures, dysarthria, and/or coma. CT was nondiagnostic. MRI clearly demonstrated multifocal white matter lesions of the cerebrum, brainstem, and cerebellum which corresponded to clinical signs. The patients improved dramatically with corticosteroid therapy. MRI showed progressive resolution of multifocal lesions in conjunction with clinical improvement.

Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system. We describe here a patient who developed ADEM after allogeneic bone marrow transplantation (BMT). A 48-year-old woman with acute myeloid leukemia (M2) underwent allogeneic BMT from her HLA-identical sister. Cyclosporin for prophylaxis of acute graft-versus-host disease (GVHD) was discontinued from day 15 because of its toxicity. She was relatively well after the resolution of cytomegalovirus reactivation and chronic GVHD. Nine months after BMT, she suddenly developed diplopia, dysarthria, and gait disturbance. Computed tomography of the brain at that time revealed no abnormal findings. Leukemia recurrence was not revealed. The neurological symptoms were very mild without further deterioration. Her clinical course was carefully watched without therapy. Two weeks after onset, fluid attenuated inversion recovery magnetic resonance imaging (MRI) revealed multifocal abnormal high-signal intensity mainly in the white matter of the cerebrum as well as in the cerebellum and brainstem. Cerebrospinal fluid examination showed no abnormal findings. No laboratory findings suggested the presence of infectious agents. The typical MRI findings and an acute monophasic clinical course of this patient led to a diagnosis of ADEM. Twelve weeks after onset, the symptoms had almost resolved. Follow-up MRI showed a substantial improvement of the previous lesions without any new lesions. The symptoms had completely resolved 5 months after onset. This is a rare case of ADEM developing after allogeneic BMT.

Acute cerebellar ataxia and acute cerebellitis represent a process characterized by parainfectious, postinfectious, or postvaccination cerebellar inflammation. There is considerable overlap between these entities. The mildest cases of acute cerebellar ataxia represent a benign condition that is characterized by acute truncal and gait ataxia, variably with appendicular ataxia, nystagmus, dysarthria, and hypotonia. It occurs mostly in young children, presents abruptly, and recovers over weeks. Neuroimaging is normal. Severe cases of cerebellitis represent the other end of the spectrum, presenting with acute cerebellar signs often overshadowed by alteration of consciousness, focal neurological deficits, raised intracranial pressure, hydrocephalus, and even herniation. Neuroimaging is abnormal and the prognosis is less favorable than in acute cerebellar ataxia. Acute disseminated encephalomyelitis may be confused with acute cerebellitis when the clinical findings are predominantly cerebellar, but lesions on neuroimaging are usually widespread. Paraneoplastic opsoclonus-myoclonus syndrome is often initially misdiagnosed as acute cerebellar ataxia, but has very specific features, course, and etiopathogensis.
