Write answer in between .Q:A 27-year-old G2P0A2 woman comes to the office complaining of light vaginal spotting. She received a suction curettage 2 weeks ago for an empty gestational sac. Pathology reports showed hyperplastic and hydropic trophoblastic villi, but no fetal tissue. The patient denies fever, abdominal pain, dysuria, dyspareunia, or abnormal vaginal discharge. She has no chronic medical conditions. Her periods are normally regular and last 3-4 days. One year ago, she had an ectopic pregnancy that was treated with methotrexate. She has a history of chlamydia and gonorrhea that was treated 5 years ago with azithromycin and ceftriaxone. Her temperature is 98F 36.7C, blood pressure is 12571 mmHg, and pulse is 82min. On examination, hair is present on the upper lip, chin, and forearms. A pelvic examination reveals a non-tender, 6-week-sized uterus and bilateral adnexal masses. There is scant dark blood in the vaginal vault on speculum exam. A quantitative beta-hCG is 101,005 mIUmL. Two weeks ago, her beta-hCG was 63,200 mIUmL. A pelvic ultrasound shows bilaterally enlarged ovaries with multiple thin-walled cysts between 2-3 cm in size. Which of the following is the most likely cause of the patients adnexal masses?? A: Corpus luteal cysts, B: Dermoid cysts, C: Ectopic pregnancy, D: Endometrioma, E: Theca lutein cysts,  <response>: This is a clinical vignette about a 27-year-old woman with a history of ectopic pregnancy and abortion who now presents with vaginal bleeding, enlarged ovaries with cysts, and rising beta-hCG levels. The key findings are:- Recent suction curettage for an empty gestational sac - Pathology showed hydropic trophoblastic villi suggesting gestational trophoblastic disease- Bilateral adnexal masses and thin-walled ovarian cysts on ultrasound - Markedly elevated and rising beta-hCG levels This presentation is most consistent with gestational trophoblastic disease, specifically choriocarcinoma. The adnexal masses are likely theca lutein cysts which can develop as a result of the abnormally high beta-hCG levels stimulating ovarian hyperstimulation.E: Theca lutein cysts
