[A boy with a rare pulmonary disease; COVID-19 is clouding our judgment]. / Een jongen met een zeldzame longziekte.

BACKGROUND: In times of coronavirus, a patient with respiratory symptoms whose chest CT scan reveals ground-glass opacities, COVID-19 may seem an obvious diagnosis. CASE DESCRIPTION: At the (currently assumed) peak of the coronavirus crisis, a 12-year-old boy was admitted to the hospital twice for severe respiratory symptoms. A chest CT scan revealed ground-glass opacities.COVID-19 pneumonia was initially thought of. However, it turned out to be a rare interstitial pulmonary disease. CONCLUSION: Due to the increased awareness about COVID-19, tunnel vision is lurking. Even during a health crisis, doctors should remain alert to alternative diagnoses.
