A Case of Lymphangiomatosis With Infected Lymphangiomas Effectively Treated by Thoracoscopic Debridement and Drainage.

A 40-year-old woman with lymphangiomatosis also had an intrathoracic lymphangioma infection. Since the age of 8 years, the patient had undergone repeated abdominal and mediastinal cyst surgeries and had received a diagnosis of lymphangiomatosis. At this time, she showed a high fever of 38.5°C. Cultures of both blood and fluid aspirated from the cyst were positive for Staphylococcus aureus. Chest CT imaging revealed an enlarged right-sided mediastinal cystic lymphangioma with new septa in it. A chest tube was inserted into the cyst to remove effusion. The patient was then started with the antibacterial drug cefazolin at 3 g/d. But effective drainage was difficult because of the high viscosity of the effusion and septa working as barriers. We removed these components with endoscopic surgical instruments and via a pulsed-lavage system under general anesthesia. Postoperative CT images showed reexpanded lung structure and reduced cyst size. The patient has taken a favorable course for 2 years.
