Enterovirus 71 infection

Case contributed by Dr Jeremy Jones

Presentation

Ascending paralysis with progressive loss of motor skills in the legs

Patient Data

Age: 22 months
Gender: Male
Modality: MRI

There is T2 hyperintensity and enhancement of the left anterior horn cell at L2 with accompanying thickening and enhancement of the anterior nerve roots of the cauda equina. No focal mass lesion.

Case Discussion

In this case, there is enhancement of the anterior nerve roots of the cauda equina. This can be seen in Guillain-Barré syndrome. However, with the T2 hyperintensity of the anterior horn cell and accompanying enhancement, this diagnosis does not fit.

Instead, think of polio virus infection and enterovirus 71 infection, the latter of which was confirmed on PCR.
