[For a conservative treatment of hydatid cyst of the spleen].

A retrospective study of 45 cases of spleen hydatic cyst. Operated on between January 1980, and December 1989 permitted the following commentary. Splenic hydatic cyst is characterized by its rarity and latency. It's diagnosis gives no rise to any problems. Echography data are essential in asymptomatic froms associated to other localisations. Surgical treatment can not be summarised to splenectomy; conservative methods are used as long as possible.
