[Thoracic and retroperitoneal cystic lymphangiomyomatosis. Value of lymphography]

Standard radiological examinations in a woman of 40 years of age with a pneumothorax and chylothorax revealed the presence of a posterior mediastinal mass compressing the oesophagus, and an interstitial syndrome. Retroperitoneal and mediastinal cystic lymphangiomas were found on lymphography. These findings are in accordance with the lymphangiomyomatosis described by Cornog and Enterline in 1966. The similarity between this disease and tuberculous sclerosis is underlined in present-day publications.
