Summary
Early diagnosis of lymph node metastasis after pneumonectomy is possible with FDG-PET/CT. This finding in a pericardial fat flap used for bronchial stump coverage led to successful treatment via resection and radiation.
Area of Science:
- Thoracic Surgery
- Oncology
- Diagnostic Imaging
Background:
- Bronchopleural fistula is a severe complication following pneumonectomy for lung cancer.
- Bronchial stump coverage, often with a pedicled pericardial fat flap, is standard practice to prevent fistulas.
- Recurrence of lung cancer can occur, necessitating vigilant post-operative monitoring.
Observation:
- A case report details a patient who previously underwent left lung resection for cancer.
- A lymph node metastasis was identified within the pedicled pericardial fat flap used for bronchial stump coverage.
- This metastasis was detected using Fluorodeoxyglucose-Positron Emission Tomography/Computed Tomography (FDG-PET/CT) during post-operative treatment.
Findings:
- FDG-PET/CT enabled early diagnosis of lymph node metastasis in the bronchial stump coverage flap.
- The identified recurrence was successfully treated with en bloc resection.
- Adjuvant radiation therapy was administered following the surgical intervention.
Implications:
- FDG-PET/CT is a valuable tool for the early detection of metastatic recurrence in unusual locations after pneumonectomy.
- This case highlights the importance of monitoring bronchial stump coverage flaps for potential cancer spread.
- Prompt diagnosis and multimodal treatment (surgery and radiation) can lead to successful outcomes in managing post-pneumonectomy recurrence.
