Introduction:
We describe the first case of acute flaccid myelitis (AFM) related to enterovirus D68 (EV-D68) infection in Belgium. The clinical and radiological presentation of AFM associated with EV-D68 although well described currently remains a challenging diagnosis. Through this interesting clinical case, we aimed to review the differential diagnosis of acute flaccid palsy in a child and discuss the specific point of interest related to AFM.
Case Presentation:
We present the case of a 4-year-old girl with a torticollis associated with an acute palsy of the right upper limb. The magnetic resonance imaging revealed an increased T2 signal intensity of the entire central gray matter of the cervical cord with involvement of the posterior brainstem. A polymerase chain reaction (PCR) conducted on a nasopharyngeal swab was found positive for EV-D68. The definition of AFM proposed by the Center for Disease Control and Prevention (CDC) is an acute-onset flaccid weakness of one or more limbs in the absence of a clear alternative diagnosis and the radiological evidence of gray matter involvement on an MRI picture, and our case fits these two criteria. A prompt and detailed workup is required to distinguish this emergent disease from other forms of acute flaccid palsy. The functional prognosis of AFM is poor, and there are no evidence-based treatment guidelines so far.
Conclusion:
AFM is an emerging pathology that requires the attention of pediatricians to quickly rule out differential diagnoses and adequately manage the patient. Further research is needed to optimize treatments, improve outcomes, and provide scientifically based guidelines.
Insights
This case study details the first Belgian patient with acute flaccid myelitis (AFM) caused by enterovirus D68 (EV-D68). Early diagnosis and management are crucial for this challenging neurological condition in children.
Area of Science:
- Neurology
- Pediatrics
- Infectious Diseases
Background:
- Acute flaccid myelitis (AFM) is a rare but serious neurological condition.
- Enterovirus D68 (EV-D68) is an emerging cause of AFM.
- Belgium reports its first case of AFM linked to EV-D68.
Observation:
- A 4-year-old girl presented with torticollis and acute right upper limb palsy.
- MRI revealed cervical cord gray matter and brainstem involvement.
- PCR confirmed EV-D68 infection from a nasopharyngeal swab.
Findings:
- The patient met the CDC criteria for AFM, including acute onset, flaccid weakness, and characteristic MRI findings.
- EV-D68 was identified as the causative agent.
- The case highlights diagnostic challenges and the need for prompt evaluation.
Implications:
- AFM requires prompt recognition and differentiation from other causes of acute flaccid palsy.
- Further research is needed for effective treatments and management guidelines.
- Pediatricians must be vigilant for this emerging pathology.
