when a follicle doesn't rupture (aka anovulation) then it will form a cyst.

for anyone who thought it was endometriosis its not because endometriosis of the ovary would have multiple blood filled "chocolate cysts" and presents bilaterally and patient would typically have pelvic pain as well FA 2019:p634

The most common cyst in a young female is Follicular cyst; this is a cystic dilatation of an unruptured Graffian follicle.

Failure of Graffian follicle to rupture --> Anovulation

Ref FA2019 Pg 631-632

Why i think this is a bullshit question. Asymptomatic, so it rules out Endometriosis because there will be pain every menstrual cycle because endometrium in ovaries also bleeds. Also rules out PID because no Sx such as fever and vaginal discharge. Also rules out ectopic pregnancy No unilateral pain, and other sign and Sx of pregnancy Now stuck with 2 Malignancy and Anovulation cyst. so They say patient is asymptomatic and in case of anovulation cyst there will be prolong abscence of menses and then massive bleeding so that is a symptom and it must be present if anovulation because there will be prolong follicular phase and unopposed estrogen release. so i picked ovarian neoplasm which is usually asymptomatic over long period of time but it does not fit with the age. So you have to chose between age demography and ignoring irregular menses as a symptom.

This was literally the most vague shit I've ever read.

But basically my reasoning was that:

Endometriosis of the ovary would cause chocolate filled cysts, and there would be cyclical menstrual pain. This patient is asymptomatic, so this is ruled out.

Ectopic pregnancy would present with a growing fetus or fetal tissue in the ampulla, fallopian tube, ovarian surface. This is an acute emergency, not a cyst, and would present like acute appendicitis, severe lower abdominal pain on either the right or left side. Again, nope.

I couldn't rule out malignancy by any rational thought process, but in this patient demographic with absolutely 0 symptoms, and one single fluid filled cyst I was thinking of a follicular cyst (FA 2018 pg 628). It kinda helped that I was instinctively leaning towards PCOS as a diagnosis the moment I heard cysts in a young woman, and I knew that the cysts in PCOS are due to anovulation.

the key here is (asymptomatic) the only amswer is anovulation

The owners are a bunch of assholes they just took everyones descriptions and are now trying to make money off of it you guys are useless

After everything its jjust an epidem ques. Below 55 vs Above 55 years
