Various sonographic appearances of the hemorrhagic corpus luteum cyst.

Although hemorrhagic corpus luteum cysts are frequently seen during sonography of the female pelvis, their diagnosis is often challenging as a result of variations in size, thickness of the cyst wall, and internal echo pattern depending on the formation and lysis of the clot. There are cases in which hemoperitoneum is the most obvious finding. The differential diagnosis is extensive and includes ectopic pregnancy, adnexal torsion, neoplasm, and pelvic inflammatory disease. This review describes and illustrates the diverse appearances of the hemorrhagic corpus luteum, as well as other etiologies of adnexal pathology that can mimic the appearance of a hemorrhagic corpus luteum sonographically.

Persistant corpus luteum cyst of pregnancy: sonographic evaluation of cause of third trimester bleeding.

Corpus luteum cysts are frequently observed in pregnant patients evaluated with diagnostic ultrasound. They are usually regarded as incidental findings because of their limited size and usual pattern of regression by ten weeks. The presence and persistence of larger corpus luteum cysts or other extrauterine masses may complicate pregnancy. A case of a large persistent corpus luteum cyst associated with third trimester bleeding is presented.

Ectopic pregnancy versus corpus luteum cyst revisited: best Doppler predictors.

OBJECTIVE: To determine the best Doppler values for differentiating ectopic pregnancy from a corpus luteum cyst of pregnancy. METHODS: This was a prospective study of 80 consecutive patients with the diagnosis of ectopic pregnancy. All ectopic pregnancies were diagnosed on the basis of the presence of an extra-ovarian adnexal mass on sonography and were confirmed surgically. The last menstrual period ranged from 4 to 11 weeks (mean, 6.3 weeks), and the maximal ectopic pregnancy diameter ranged from 0.7 to 5.5 cm (mean, 2.5 cm). Seventy-six ectopic pregnancies showed color vascularity, and 40 showed corpus luteum cysts with vascular walls. The highest peak systolic velocity and the lowest resistive index of the vascular ectopic pregnancies were compared with the corresponding values in the vascular corpus luteum cysts. RESULTS: The mean peak systolic velocity of the ectopic pregnancies was 35.4 cm/s compared with 28.4 cm/s in corpus luteum cysts, with no significant statistical difference (P = .1). The resistive index of the ectopic pregnancies ranged from 0.15 to 1.6 (mean +/- SD, 0.61 +/- 0.24) compared with 0.39 to 0.7 (mean, 0.52 +/- 0.10) in corpus luteum cysts, with a significant statistical difference (P = .003). In this cohort, a resistive index of less than 0.39 had a specificity of 100% and a positive predictive value of 100% for diagnosing ectopic pregnancy but was present in only 15% (confidence interval, 7%-23%) of ectopic pregnancies. A resistive index of greater than 0.7 had a specificity of 100% and a positive predictive value of 100% for diagnosing ectopic pregnancy and was present in 31% (confidence interval, 21%-41%) of ectopic pregnancies. CONCLUSIONS: Both low and high resistive indices discriminate ectopic pregnancy from a corpus luteum cyst.

Serous culdocentesis in ectopic pregnancy: a report of two cases caused by coexistent corpus luteum cysts.

Two cases of women with large-volume serous culdocentesis results are presented. Both patients ultimately had ectopic pregnancies diagnosed surgically, and aspiration into coexistent corpus luteum cysts caused the "false-negative" culdocentesis results. The accuracy of culdocentesis and its continued role in the workup of the patient with possible ectopic pregnancy is reviewed. Because the corpus luteum is a cystic structure present in all pregnancies during the first seven weeks, cyst aspiration is always a possibility and should be suspected when large amounts of serous fluid are obtained by culdocentesis. Such results should be considered nondiagnostic and do not exclude a coexistent ectopic pregnancy.

Hemorrhagic corpus luteum cyst torsion in term pregnancy: a case report.

Hemoperitoneum during pregnancy resulting from spontaneous rupture of adnexal torsion is a rare cause of fetal and maternal death. Presenting symptoms include severe abdominal pain, followed rapidly by maternal shock and fetal distress. It is hard to localize the adnexae in advanced pregnancy. Here, we present a case of spontaneous rupture of hemorrhagic corpus luteum cyst torsion that had not been previously diagnosed by ultrasound during term pregnancy. The patient was sent to our emergency room for sudden onset of severe low abdominal pain. Treatment consists of maintenance of adequate circulating intravascular volume and rapid surgical intervention. Preoperative diagnosis of adnexal torsion during term pregnancy is very difficult, although it is always identified during surgery.

Repeated aspiration of ovarian follicles and early corpus luteum cysts in an in-vitro fertilization programme reduces the risk of ovarian hyperstimulation syndrome in high responders.

A retrospective analysis of ovarian hyperstimulation syndrome in high responders undergoing in-vitro fertilization (IVF) is presented. High responders were defined as having > 20 follicles and serum oestradiol > 3000 pg/ml after treatment with human menopausal gonadotrophin. Of the initial 30 IVF cycles in high responders, 23 developed a moderate-to-severe ovarian hyperstimulation syndrome (76.7%). Subsequently, 15 other IVF cycles in high responders were combined with a repeated aspiration of ovarian follicles and corpus luteum cysts just prior to embryo transfer. Only three patients (20%) developed a moderate ovarian hyperstimulation syndrome (P = 0.0004). We conclude that repeated follicular aspiration is safe and results in a significant reduction in the incidence and severity of this condition in high responders undergoing IVF.
