A rare case of Gorham-stout syndrome involving the thoracic spine with progressive bilateral chylothorax: a case report.

BACKGROUND

Gorham-Stout syndrome (GSS) with spinal involvement is extremely rare, and bilateral chylothorax as a complication is usually fatal. In our case, pleural effusion appeared in the left hemithorax after ligating the right thoracic duct.

CASE PRESENTATION: A 14-year-old patient presented with GSS affecting the thoracic spine with bilateral chylothorax. The case was successfully managed using combined conservative and surgical treatments. At the 2-year follow-up visit, the amount of pleural fluid was reduced, the patient's respiratory function had improved, and the deformity on the thoracic spine had gradually stabilized.

CONCLUSIONS

GSS is a rare disorder of the musculoskeletal system that responds poorly to therapies and exhibits very high morbidity and mortality. Chylothorax is a common complication when lesions involve the thoracic spine, and physicians should be vigilant for possible serious pulmonary complications.
