Insights
Acute disseminated encephalomyelitis (ADEM) in a teen was successfully treated with steroids after developing symptoms like double vision and weakness. Enterovirus infection was identified as a rare cause of this central nervous system demyelinating condition.
Area of Science:
- Neurology
- Infectious Diseases
- Pediatrics
Background:
- Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system (CNS).
- It often occurs post-infection or post-vaccination, presenting with multifocal white matter lesions.
- Early diagnosis and treatment are crucial for patient outcomes.
Observation:
- A 16-year-old male with a history of attention-deficit/hyperactivity disorder (ADHD) presented with acute neurological deficits.
- Symptoms included diplopia, right-sided hemiparesis, ataxia, and vomiting.
- The patient had been on risperidone for 7 years.
Findings:
- Clinical, laboratory, and cranial MRI confirmed a diagnosis of ADEM.
- Cerebrospinal fluid (CSF) analysis revealed the presence of enterovirus.
- The patient showed significant clinical improvement after pulsed methylprednisolone and subsequent prednisolone therapy.
Implications:
- This case highlights a rare association between ADEM and enteroviral infection in an adolescent.
- It underscores the importance of considering infectious etiologies in ADEM diagnosis.
- Prompt steroid treatment can lead to substantial recovery in ADEM patients.
Abstract:
Acute disseminated encephalomyelitis (ADEM) is an acute demyelinating infection of the CNS that is characterized by multifocal white matter involvement often following an infection and vaccination. A 16-year-old child receiving risperidone for 7 years for the treatment of attention-deficit/hyperactivity disorder was hospitalized with complaints of double-vision during the past month and weakness on his right side, ataxia, and vomiting over the past 3 days. The child was diagnosed with ADEM after clinical, laboratory, and cranial MRI was conducted. Following an initial 3-day therapy with pulsed methylprednisolone, the child showed obvious clinical improvement. The treatment was continued with prednisolone and significant improvement was achieved. Enterovirus was detected in the results of the viral examination of the CSF. This child was found to be an interesting case having been diagnosed with ADEM associated with enteroviral infection, because of the rarity of few case reports in the literature.
