Pneumothorax as a consequence of a malpositioned naso-gastric tube

Case contributed by Fabio Macori
Diagnosis certain

Presentation

This patient was admitted to the hospital after a fall at home in which he suffered a small subarachnoid hemorrhage and, above all, a fracture of C1 and C2 (Jefferson fracture). In order to establish enteral feeding, insertion of a nasogastric tube was performed.

Patient Data

Age: 85 years
Gender: Male

Abnormal location of the nasogastric tube traversing along the course of the trachea and the right main bronchus into the right upper abdomen. There are a small apical right-sided pneumothorax and a well-defined band shaped opacity in the medial right lower zone suspicious of atelectasis (differential diagnosis aspiration or hemorrhage). 

The feeding tube was immediately removed.

Non-contrast CT post-NG-removal shows the presence of a significant right pneumothorax and extensive atelectasis at the right base; pleural effusion is seen.

The site of iatrogenic lung and diaphragm laceration is not recognisable with certainty.

Mild basal atelectasis controlateral is present in this long-suffering patient.

Case Discussion

Nasogastric placement is a frequently performed procedure for hospitalized, particularly critically ill patients, and although it seems a simple procedure, it may carry potential life-threatening complications due to misplacement.

Chest X-ray after insertion of the NG tube is considered a gold standard to assess the right positioning in the stomach.

The case illustrates some of the complications that can occur in case of feeding tube misplacement.
