Ovarian
Ovarian Cysts
Functional Cysts
- Follicular cysts (MC) associated with ↑ estrogen
When follicle does not rupture and release egg
- Corpus luteum cysts associated with ↑ progesterone only BC & pregnancy
Produces progesterone ➔ delayed menses
US shows ovarian cysts with variably thick walls and ↑ vascularity
- Theca lutein cysts associated with ↑ LH/FSH and HCG
Multiple gestations and gestational trophoblastic disease
US shows multiple cysts with thin walls
Nonfunctional cysts
Chocolate - menstrual debris
Dermoid - somatic tissue (hair/teeth/glands)
Cystadenoma - serous (watery) or mucinous (gelatinous)
Malignant - type of ovarian cancer
SSX: Asx or palpable adnexal mass
SSX of rupture: Sudden onset of unilateral lower abd pain typically after physical activity
Can ➔ torsion (if >5cm) OR rupture ➔ hypovolemic shock
± N/V, spotting
DX
HCG to r/o ectopic
US to r/o torsion
Rupture: Rectouterine pouch fluid (pouch of Douglas) ± visualized mass
Mass and fluid in pouch can be seen in ruptured ectopic
CT with contrast if not pregnant and US not helpful
Must r/o ovarian cancer, especially if pre or postmenopausal
TX
Cysts often resolve, NSAIDs for pain
Rupture and unstable ➔ emergency lap-exploration to stop bleeding, may need oophorectomy
Rupture and unstable ➔ analgesics and monitor for bleeding (hypotension, H&H)
Polycystic ovarian syndrome
Insulin insensitivity (causal or consequence) ➔ obesity/overweight, insulin insensitivity
PCOS ➔ ↑ risk of endometrial cancer and ovarian cancer
HPA axis problem: LH > FSH
↑ LH ➔ ↑ androstenedione (androgen) ➔ peripheral estrogen ⊣ FSH
↑ LH ⊣ LH surge ➔ anovulation/oligoovulation ➔ amenorrhea
↑ androgens ➔ hirsutism, acne
DX
Clinical evidence and/or biochemical evidence of hyperandrogenism AND one year of abnormal menstruation
Hirsutism, acne, ♂ pattern baldness and/or
LH >> FSH ratio,↑ androstenedione ,↑ testosterone, ↓ sex hormone binding globulin
R/o Cushing, adrenal hyperplasia, hyperprolactinemia
US shows ovarian volume >10mL/multiple cystic follicles (string of pearls)
TX
Lifestyle (diet, exercise) most important
Dual oral contraceptives (same VTE risk)
If concern about estrogen exposure ➔ medroxyprogesterone or progestin IUD
Add anti-androgens (spironolactone > finasteride) at 6mo if refractory
If trying to get pregnant: Metformin or letrozole or clomiphene
Ovarian Cancer
Epithelial carcinoma (MC), germ cell tumors, sex cord/stromal tumors
Unopposed estrogen, PCOS, ➔ ↑ risk
Dual oral contraceptive is protective (estrogen opposed by progestin)
SSX
Mild and nonspecific sx
Adnexal mass ➔ bloating, non specific pelvic pain ("pants don't fit but losing weight")
Early satiety, ∆ urine
Spotting, postmenopausal bleeding (endometrial cancer > ovarian cancer)
Advanced/metastasis
Bowel obstruction, torsion, jaundice/ascites
ABD pain from omental caking, LN (supraclavicular/inguinal)
DX
Pelvic US (trans-abd and trans-vag)
Vascularization, irregularly thick septa with indistinct borders, free fluid consistent with ascites
Non-surgical biopsy and FNA should not be done (↑ risk of spreading)
CT evaluate for mets
↑ tumor marker CA-125 (used for monitoring)
↑ CA-125 premenopausal likely benign
↑ CA-125 in postmenopausal ➔ ↑ concern for malignancy
CA-125 is also elevated in PID, pregnancy, endometriosis
TX is surgical staging with debulking with adjuvant chemo
Hysterectomy Bilateral salpingo oophorectomy
Omentectomy
Pelvic and paraaortic LN dissection
Peritoneal cytology
Torsion
Risk factors: MCC is ovarian mass (tumor/cysts >5cm), pregnancy
Ovary and fallopian tube twist around infundibulopelvic and ovarian ligament
➔ ↓ outflow ➔ fallopian tube and ovary edema ➔ ↓ arterial blood supply ➔ ischemia ± necrosis
SSX
Sudden onset of unilateral lower abd pain typically after physical activity
± N/V, spotting, palpable mass
DX
HCG to r/o ectopic
US: Edematous (enlarged) and heterogenous ovary with ↓ blood flow, thick fallopian tube, twisted pedicle
MRI > CT with contrast if US not helpful
TX - lap-exploration for any suspected ovarian torsion
Premenopausal: adnexal detorsion trying to save ovaries
Postmenopausal: salpingo-oophorectomy
