Mediastinal cystic lymphangiomas are rare tumours. Usually asymptomatic, they can
be complicated by a chylopericardium or/and chylothorax. We report a case of a left
lesion infiltrating through the supra-aortic vessels complicated with a iatrogenic
left chylothorax managed by bilateral video-assisted thoracoscopy at the same time.
First, on the right, the chylous inflow was stopped by suturing the thoracic duct;
then, on the left, a fenestration was done to confirm the diagnosis and treat the
lesion while preserving the adjacent structures.
