Background: Splenic cysts represent a pathology seldom encountered in practice, the most often etiology being, parasitic, congenital and pseudo–cysts, which usually appear post–traumatically or after a splenic infarction.Splenic cysts indicate a surgical treatment when they are large (and thus present a high risk for complications such as rupture, hemorrhaging, compression of the neighboring organs), when they are symptomatic or present complications.

Case report: We present the case of a patient diagnosed with splenic cyst in our Clinic, its discovery being incidental, while conducting investigations for an abdominal pain syndrome.

Discussions: The clinical case presented completely abides to the literary description–the diagnostic has been incidental, the large size of the cyst has determined the need for surgery (splenectomy), its etiology has been established by means of anatomo–pathological report (the presence of the epithelial inner wall that indicates congenital cysts).
