[Cystic abdomino-mediastinal lymphangioma. Apropos of a case. Review of the literature].

A further case of cystic lymphangioma is reported, characteristic features being the multiple abdominal and thoracic localizations of the lesions. Apart form splenic sites, it is rare to detect lesions in the mesogastric and mediastinal regions, particularly as propagation of abdominal lymphangioma towards the mediastinum is an exceptional occurrence. A literature review provides data on the various regions in which cysts have been reported in the body, and the diagnostic problems they raise.
