Multiple Choice

A tall, slender, 20-year-old male reports a two-day cough and left-sided chest pain. What should you suspect?

A tall, slender young man with sudden chest pain points to a primary spontaneous pneumothorax. In people who are tall and thin, small air-filled blebs can rupture on the lung’s surface, allowing air to enter the pleural space. This air buildup causes the lung to partially collapse and produces pleuritic chest pain and often shortness of breath. The two-day cough doesn’t rule this in and, in someone this age and body type, it’s the pattern that fits best. Other conditions don’t fit as well with this patient’s profile. A pulmonary embolism can cause chest pain and dyspnea but is less likely in a 20-year-old without risk factors. A pleural effusion typically presents with progressive symptoms and findings like dullness to percussion or reduced breath sounds and is more common in older patients with comorbidities. Myocardial infarction is unlikely in someone so young and without risk factors. So, the presentation most consistent with a spontaneous pneumothorax is air leaking into the pleural space from ruptured apical blebs in a tall, thin young man.
