Thrombocytosis, haemorrhagic pleural effusion and fibro-infiltrative patches with cavitary lung lesions in a child with COVID-19 pneumonia.

COVID-19 infection in children is relatively mild and is associated with fewer complications compared with adults. Here we report the case of a previously healthy preteen girl who presented with active COVID-19 and shock. On day 1, ultrasound of the thorax revealed a right-sided pleural effusion with haemorrhagic pus on diagnostic tap, which improved clinically with appropriate hospital treatment.
