Asymptomatic lymphangioma involving the spleen and mediastinum in adults.

Developmental malformation of the lymphatic system and cystic proliferation of lymphatic vessels causes a very rare condition known as cystic lymphangioma. The malformation may involve the spleen alone or be a part of multiorgan involvement. We describe a case of cystic splenic cystic lymphangioma accompanied with mediastineal lymphangioma in a middle age woman with the emphasis on the rarity of the case in adults and the difficulties of the differential diagnosis.
