Cul de Sac Fluid

Cul de sac fluid is a common ultrasound finding in women of reproductive age and can be a normal finding or suggest a problem that needs to be investigated based on the context.

Cul de sac fluid normally accumulates after a follicle has ruptured and indicates a woman has ovulated. In some cases, excessive cul de sac fluid is a sign of an acute problem that needs to be addressed including a ruptured ovarian cyst, ovarian hyperstimulation syndrome (OHSS), or ectopic pregnancy.
