Case 336
Veniamin Barshay, MD
Clinical Presentation: Patient is a 92-year-old female status post nasogastric (NG) tube placement.
Imaging Findings: The abdominal radiograph demonstrated a NG tube curled in the right hemithorax, consistent with airway placement with the tip in the pleural space. The follow up radiograph (Fig. 2) demonstrated right pneumothorax. The NG tube was repositioned in the stomach.

Diagnosis: Tracheobronchial malposition of the NG tube with pneumothorax
Discussion: Nasogastric intubation has become a standard of practice in the intensive care patient. There is inherent risk of malposition of the tube in the airways. The complications are potentially serious and include atelectasis, severe pneumonia, pneumo- and hemothorax. The frequency of the nasogastric tube malposition is difficult to evaluate. Various literature sources report it to be 0.5 to 1.5 % of the attempted intubations. The severity of potential complications illustrates the utility of appropriate placement confirmation by radiograph, when available.
