Summary
A rare cervical thoracic duct cyst was surgically removed from a 28-year-old female. This case offers insights into the pathogenesis and fluid retention mechanisms of these unusual lymphatic malformations.
Area of Science:
- Vascular Surgery
- Surgical Pathology
- Medical Imaging
Background:
- Thoracic duct cysts are rare lymphatic malformations.
- Cervical location of thoracic duct cysts is exceptionally uncommon.
- Diagnosis often requires a combination of clinical presentation and imaging.
Observation:
- A 28-year-old female presented with a supraclavicular fossa tumor.
- Exploratory puncture revealed milky-white, lipid-rich fluid, indicative of chyle.
- Lymphography showed adjacent lymphatic structures and vessels on the cyst surface.
Findings:
- A unilocular cyst, approximately 6 cm in diameter, was identified.
- Histological examination confirmed the diagnosis of thoracic duct cyst.
- A potential, though unclear, communication with the thoracic duct was noted during resection.
Implications:
- This case contributes to understanding the pathogenesis of thoracic duct cysts.
- The findings may elucidate the mechanisms of cyst fluid retention.
- Highlights the importance of considering rare lymphatic anomalies in cervical masses.
