Summary
A rare case of iatrogenic foreign body granuloma, caused by retained surgical gauzes after 28 years, presented as a mediastinal tumor. A whirl-like pattern on MRI was a key diagnostic finding.
Area of Science:
- Thoracic Surgery
- Surgical Pathology
- Diagnostic Imaging
Background:
- A 45-year-old male presented with a dry cough and a right anterior mediastinal mass detected via chest X-ray and CT scan.
- Preoperative diagnosis suggested teratoma, necessitating surgical intervention.
Observation:
- Thoracotomy revealed a foreign body granuloma originating from surgical gauzes, presumed to be retained from a right upper lobe segmentectomy for tuberculosis 28 years prior.
- The granuloma was iatrogenic, a rare complication with few documented cases.
Findings:
- Macroscopic and microscopic examination confirmed the foreign body granuloma.
- Retrospective analysis identified a whirl-like pattern on MRI as a significant diagnostic clue.
Implications:
- This case highlights the importance of meticulous surgical practice to prevent retained foreign objects.
- The MRI whirl-like pattern may aid in the preoperative diagnosis of such rare iatrogenic complications.
- Increased awareness and reporting of such cases are crucial for surgical education and patient safety.
