Longitudinally Extensive Transverse Myelitis (LETM) and Myopericarditis in a 7-Month-Old Child with SARs-CoV-2 Infection.

 To the evolving literature of neurological complications of SARs-CoV-2 infection, we add the youngest patient described to date with isolated LETM and concomitant cardiac involvement. Our case suggests that clinicians should be aware of this association, although difficult to recognize in infants. Practitioners are encouraged to consider aggressive first-line immunotherapies with the final aim to prevent permanent disability.
