The patient was taken in to hospital due to left-sided bronchopneumonia.

The ultrasound examination shows alveolar consolidation („shred sign“). After antibiotic therapy the findings did not regress, so a biopsy was performed under ultrasound observation, which confirms interstitial pneumonia, after corticoid the findings regressed.

The „shred sign“ is a non-homogeneous hypoechoic shredded structure, blurry, as if it has been shredded to demarcate the surrounding area.
