She was admitted on September 20, 2014, with a poor general condition, complaints of neck pain, upper airway symptoms, abdominal pain, vomiting, and later increasing muscular weakness. Respiratory failure due to muscle weakness led to intubation two days later and an MRI-scan revealed oedema of the brain stem and cordal grey matter, extending from upper brainstem to the thoracolumbar level. Enterovirus-D68 was identified in the nasopharyngeal specimen. After 2 months she has recovered slightly but still has severe neurological symptoms. The patient cannot stand or sit unsupported, and head control is poor. Motor impairment is worse proximally and more pronounced in upper extremities and neck. She relies on nasogastric tube-feeding, and has poor swallowing function. CPAP on a tracheal tube can be paused shortly. She started speaking this week. Enterovirus D68 is increasingly associated to Acute Flaccid Paralysis, mainly in children, and most cases are from USA and Canada. This is to our knowledge the second reported case from Europe. Both became sick in September 2014. Awareness toward this possible neurological complication of enterovirus D68 infection is needed.
