Spontaneous pneumomediastinum
Statistics from Altmetric.com
Description
A 17-year-old male patient presented with non-exertional central chest tightness with gradual onset. There was no history of trauma. Physical examination was normal. CT scan of his thorax showed a pneumomediastinum with no other abnormalities. Further questioning revealed that he was doing vigorous sit-up exercises a few days before his presentation (figure 1). A repeat chest x-ray a few days later showed a resolution of his pneumomediastinum. He was completely well on follow-up a few weeks later without any intervention.1 The patient was reassured about the benign nature of this uncommon condition.
