Nonelevation of serum CA 19-9 level in a true nonparasitic splenic cyst.

The diagnosis and management of true nonparasitic splenic cysts has markedly changed in recent years. The use of serum CA 19-9 has been increasingly advocated for diagnosis, while the advent of minimally invasive surgery has radically altered surgical management. We present the first case of a true nonparasitic splenic cyst in which serum CA 19-9 was not elevated. Treatment was by laparoscopic cyst decapsulation utilising the endoscopic Ligasure.
