Chest

A 34-year-old man presented to a community hospital with sudden-onset pleuritic chest pain on a background of a 12-month indolent history of progressive exertional dyspnea. He denied cough, fevers, night sweats, or weight loss. ⋯ He had a history of gastroesophageal reflux and was a current smoker with a 20-pack year history. There were no known occupational or environmental exposures and there was no family history of any lung disease.

Pulmonary bullae and blebs can result in a pneumothorax. Their prevalence in the normal population is currently unknown. Postmortem CT (PMCT) images from a forensic database were used to determine the prevalence of pulmonary bullae/blebs in the normal Dutch adult population and its consequence for diving medicine, as bullae and blebs are often considered a contraindication for diving. ⋯ By reassessing pulmonary PMCT scans, we found a surprisingly high incidence of small bullae and/or blebs in one-third (33.8%; 95% CI, 25.7-41.9) of the general population without underlying lung disease. This finding can have potential implications for diving medicine.
