Foreign body aspiration, achalasia
An 84-year-old man presented with acute respiratory distress thought secondary to aspiration pneumonia. Although limited to a seated study, a recent barium swallow showed esophageal dilatation associated with low amplitude tertiary waves. This was secondary to a tight and smooth narrowing in the distal esophagus consistent with achalasia  (Figure 1a).
Pulse oximetry on a fraction of inspired oxygen of 21% showed a reduced saturation of peripheral oxygen at 86%. Respiratory examination revealed reduced air entry at the right base, but no stridor. Chest X-ray did not reveal any abnormalities. His respiratory status deteriorated despite appropriate antimicrobial, anti-inflammatory and bronchodilator therapy.
Bronchoscopy was performed due to a high clinical suspicion of foreign body aspiration and this showed a tablet in the right main bronchus (Figure 1b) that disintegrated on attempted retrieval. Following the procedure the patient required invasive ventilation via tracheostomy and was eventually palliated following discussion with family. Significant complications of foreign body aspiration in adults have been reported, including obstructive pneumonitis, atelectasis, bronchiectasis and lung abscess . Although rare, achalasia has a well-recognized association with foreign body aspiration [3-5] and a high index of suspicion is required to ensure appropriate management.
