Peritoneal inclusion cyst: effects on fertility and antepartum course.

Abstract

Hormone changes are thought to influence the etiology and disease process of peritoneal inclusion cysts. The effects of fertility and pregnancy on preexisting cysts are unknown. A 29-year-old woman with recurrent peritoneal inclusion cyst and primary infertility conceived spontaneously after hysterosalpingogram. She presented in the first trimester with rapid, symptomatic enlargement of a 22-cm peritoneal inclusion cyst. Ultrasonogram-guided aspiration was performed. The remainder of her pregnancy and postpartum course were uncomplicated. The presence of a large peritoneal inclusion cyst does not preclude fertility. Pregnancy, a hyperestrogenic state, together with rising human chorionic gonadotropin is a risk for recurrence or enlargement of a preexisting peritoneal inclusion cyst. After conservative management with cystocentesis, there was no further enlargement as pregnancy progressed.
