Spontaneous rupture of a non-parasitic splenic cyst.

Rupture of a non-parasitic splenic cyst is a rare but possibly dangerous complication with 21 cases described so far. We present a 46-year-old woman who presented with acute abdominal pain and was diagnosed with a spontaneous ruptured splenic cyst that was successfully treated by laparoscopic splenectomy. Histological examination showed characteristics corresponding with a non-parasitic congenital cyst that had lost its epithelial lining.
