Missed Foreign Body Aspiration: Fentanyl Patch Leading to Severe Pneumonia and Empyema

TL;DR

A patient with severe pneumonia and empyema was found to have a hidden fentanyl patch in the lung, highlighting the importance of checking for foreign body aspiration in similar cases.

Contribution

Highlights a rare case where a fentanyl patch caused severe lung infection, emphasizing the need for foreign body evaluation in at-risk patients.

Findings

A fentanyl patch was identified as the source of severe pneumonia and empyema in a patient with complex medical history.

Removal of the foreign body led to significant clinical improvement.

Multidisciplinary care was crucial for successful patient recovery.

Abstract

Empyema, defined as a purulent pleural effusion within the pleural cavity, typically results from severe infections and presents significant diagnostic and therapeutic challenges. This case report details the intricate clinical journey of a 44-year-old male with a complex medical history, including chronic substance abuse, significant tobacco use, and untreated hepatitis C, who presented with acute respiratory failure, hypoxia, and right-sided chest pain. Despite initial management with antibiotics and chest tube drainage, the patient's condition necessitated advanced surgical intervention due to persistent sanguineous output.

A right thoracoscopy converted to open thoracotomy with decortication was performed due to dense adhesions. Intraoperatively, bronchoscopy revealed a hidden fentanyl patch in the right lower lobe, which was removed, leading to a significant release of purulent material and marked improvement in the patient’s condition. Postoperatively, the patient steadily recovered with decreased oxygen requirements and improved ambulation. However, he developed acute tubular necrosis, likely due to nephrotoxic medications, which was managed appropriately.

The patient was discharged with instructions for pulmonary function tests and lifestyle modifications, including cessation of tobacco use. This case emphasizes the importance of considering foreign body aspiration in patients with persistent or unexplained pulmonary symptoms, especially those with a history of substance abuse or unexplained recurrent respiratory infections. The multidisciplinary approach, comprehensive diagnostics, and collaborative care were pivotal in achieving a successful outcome, offering valuable insights for similar future cases.
