Ruptured Corpus Luteal Cyst: Prediction of Clinical Outcomes with CT

OBJECTIVE: To evaluate the determinant pretreatment CT findings that can predict surgical intervention for patients suffering from corpus luteal cyst rupture with hemoperitoneum. MATERIALS AND METHODS: From January 2009 to December 2014, a total of 106 female patients (mean age, 26.1 years; range, 17–44 years) who visited the emergency room of our institute for acute abdominal pain and were subsequently diagnosed with ruptured corpus luteal cyst with hemoperitoneum were included in the retrospective study. The analysis of CT findings included cyst size, cyst shape, sentinel clot sign, ring of fire sign, hemoperitoneum depth, active bleeding in portal phase and attenuation of hemoperitoneum. The comparison of CT findings between the surgery and conservative management groups was performed with the Mann-Whitney U test or chi-square test. Logistic regression analysis was used to determine significant CT findings in predicting surgical intervention for a ruptured cyst. RESULTS: Comparative analysis revealed that the presence of active bleeding and the hemoperitoneum depth were significantly different between the surgery and conservative management groups and were confirmed as significant CT findings for predicting surgery, with adjusted odds ratio (ORs) of 3.773 and 1.318, respectively (p 5.8 cm and concurrent active bleeding, the OR for surgery increased to 5.786. CONCLUSION: The presence of active bleeding and the hemoperitoneum depth on a pretreatment CT scan can be predictive warning signs of surgery for a patient with a ruptured corpus luteal cyst with hemoperitoneum.

Comparison on results of dual-phase enhanced CT scan and pathological diagnosis of ovarian corpus luteum cyst rupture / 中国医学装备

Objective:To compare the results of dual-phase enhanced CT scan and pathological diagnosis of ovarian corpus luteum cyst rupture.Methods: Thirty four cases of ovarian corpus luteum cyst rupture were treated in our hospital from April 2012 to April 2015 were retrospectively analyzed.Results: Among the 34 cases of patients, 28 cases before surgery CT accurate diagnosis of ovarian corpus luteum cyst, 6 cases before surgery CT did not accurately diagnose ectopic pregnancy bleeding was first diagnosed. In terms of the lesion, 22 cases of the right ovary and 12 cases were left ovary. Ruptured corpus luteum cyst diameter in 4.3-7.3cm, averaging (5.1±1.4)cm, the lack of complete cyst wall, visible break, there exists in the blood clot and the surrounding cyst; 20 cases with contrast extravasation, sheet or strip was present in high density around the cyst was the main clinical manifestations; a lot of low density liquid accumulated in the abdominal cavity; 28 cases with cystic density increased, the presence of a blood clot within the cyst was the main clinical manifestations. Surgical results were consistent with observed preoperative CT diagnosis. All patients were pathologically confirmed corpus luteum cyst rupture.Conclusion: Dual-phase enhanced CT scann has higher value in the diagnosis of ovarian corpus luteum cyst rupture bleeding, so is worthy of promotion.

Ruptured Heterotopic Tubal Pregnancy for a Patient with a History of Segmental Salpingectomy from Ectopic Pregnancy: A Case Report

Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.
