Post-Acute COVID-19 Syndrome in a 17-Year-Old: A Wolf in Sheep's Clothing

Two years into this pandemic several complications of COVID-19 are still insufficiently understood, especially in children.A 17-year-old girl presented to the pulmonary out-patient clinic primarily with shortness of breath, but additional neuromuscular and neurocognitive impairment as well as persistent headaches two month after an acute SARS-CoV-2 infection.Pulmonary function test showed massive restriction (FCV 40%), but normal diffusion capacity of CO and lung clearance index. Further extensive diagnostic work-up revealed muscular impairment and peripheral neuropathy in the lower extremities of para-infectious origin. Clinical symptoms regressed rapidly after a 5-day course of Methylprednisolone. The patient remained asymptomatic after rehabilitation treatment.
