Summary
Thoracic duct cysts in the supraclavicular region are rare. Sonography is effective for diagnosis, with surgical extirpation being the preferred treatment for these uncommon lymph vessel cysts.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Thoracic Surgery
Background:
- Supraclavicular thoracic duct cysts are rare, with limited documented cases.
- Presents as a palpable, soft, left-supraclavicular swelling.
- This study reviews five such cases encountered between 1998 and 2002.
Purpose of the Study:
- To highlight the rare diagnosis of thoracic duct cysts in the supraclavicular region.
- To emphasize the diagnostic utility of sonography for these cysts.
- To discuss the recommended treatment approach.
Main Methods:
- Sonographic evaluation of five patients with left-supraclavicular swelling.
- Surgical extirpation of the cysts and ligation of communicating lymph vessels.
- Intraoperative fluid analysis for pathohistologic confirmation.
Main Results:
- Sonography revealed hypoechogenic, polycyclic structures with specific characteristics at the jugular-subclavian vein junction.
- Surgical removal was successful in all five patients.
- Pathohistologic analysis confirmed thoracic duct cysts.
Conclusions:
- Thoracic duct cyst is a rare differential diagnosis for left supraclavicular masses.
- Sonography is the primary imaging modality for diagnosis.
- Surgical extirpation is the treatment of choice, with thoracic imaging recommended to rule out intrathoracic involvement.
