Adnexal masses in pregnancy

Adnexal masses and pregnancy: a single-center experience of 9 years

PURPOSE

This study aims to analyze the experience of a tertiary health center about the management of adnexal masses that have been diagnosed during pregnancy or detected accidentally during cesarean delivery.

METHODS

This is a retrospective review of 160 women who underwent concurrent surgery for adnexal mass during cesarean section, 24 women who delivered vaginally and subsequently had surgery due to the prenatal diagnosis of adnexal mass and 10 women who underwent surgery for adnexal mass during pregnancy. Corresponding to the delivery and surgery times, 200 women who had no diagnosis of pregnancy-associated adnexal mass served as controls.

RESULTS

The women in the control group and study groups had statistically similar gestational age at delivery, birth weight and preterm delivery (p > 0.05 for all). Miscarriage was significantly more frequent in women undergoing surgery for adnexal mass during pregnancy (p = 0.001). The women who had surgery for adnexal mass during pregnancy, at the time of cesarean section and following delivery were statistically similar with respect to surgery type and histopathological diagnosis (p > 0.05 for both). Malignancy was detected in none of the patients who underwent surgery for adnexal mass during pregnancy. Acute abdomen was the indication for the emergency surgery in six patients (3.5%) who had surgery for adnexal mass during pregnancy. Four patients (2.4%) had surgery for adnexal mass during pregnancy due to the high index of suspicion for malignancy.

CONCLUSION

The risk of malignancy was relatively lower in this cohort of adnexal masses detected during pregnancy and cesarean delivery. Surgical management of adnexal masses should be postponed to postpartum period as such management leads to an increased risk of miscarriage. Unless there is a need for emergent surgery or cancer staging, vaginal delivery should be encouraged in women diagnosed with adnexal mass during pregnancy.

Laparoscopy in Pregnancy: A Comparative Review of National Guidelines

Gynecological and general surgical conditions requiring surgical management during pregnancy constitute a medical challenge, which often entails the collaboration of numerous medical specialties. In recent years, laparoscopy in pregnancy has been accepted as a safe alternative to open surgery. This has led gynecological societies to conduct studies and issue guidelines related to laparoscopy in pregnancy, with a view to assisting and guiding clinicians and surgeons. The aim of this study was to review and compare the recommendations from various published national guidelines on laparoscopy in pregnant women. To that end, a descriptive review of guidelines from the British Society for Gynaecological Endoscopy (BSGE), the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), the Society of Obstetricians and Gynaecologists of Canada (SOCG), and the Collège National des Gynécologues et Obstétriciens Français (CNGOF) was conducted. Regarding diagnosis, the SAGES and SOCG societies recommend ultrasound as the preferred and safe imaging technique during pregnancy. In terms of the optimal timing for laparoscopic intervention, BSGE and SAGES do not restrict the laparoscopic approach based on safety, depending on the gestation week, whereas SOCG and CNGOF propose early second trimester and first and second quarter of pregnancy respectively. There is an overall consensus regarding patient positioning, initial port placement, insufflation pressure during the operation, venous thromboembolic (VTE) prophylaxis, fetal heart monitoring, and tocolysis among the reviewed guidelines. Moreover, only the BSGE mentions the need for corticosteroids, magnesium sulfate, and anti-D prophylactic administration.

The safety and effectiveness of elective laparoscopic surgery for benign ovarian cysts during pregnancy-Comparison with emergency surgery

AIM

Relatively small benign ovarian cysts are conservatively managed in early pregnancy. However, emergency surgery is required should acute abdomen occur. Our study aimed to examine and compare the outcomes of benign ovarian cysts treated with elective laparoscopic surgery or emergency surgery during pregnancy.

METHODS

From 2004 to 2017, we treated 135 pregnant patients (110 elective and 25 emergencies) with benign ovarian cysts at our tertiary perinatal center and compared their surgical and perinatal outcomes.

RESULTS

There was no significant difference in cyst diameter (7.6 ± 2.5 vs. 6.8 ± 2.1 cm), but cysts <6 cm were significantly more common in emergency (36%) than in elective (15%) cases. Mature teratomas were significantly more common in elective cases (89% vs. 52%) but corpus luteum cysts were more common in emergency cases (0% vs. 32%). The rates of laparoscopic surgery (98.2% vs. 52.0%) and ovarian conservation (99.1% vs. 80.0%) were significantly higher, and post-surgical hospitalization (4.6 ± 1.3 vs. 9.8 ± 10.5 days) was significantly shorter in elective than in emergency cases. There was no significant difference in the gestational age for delivery (38.9 ± 1.9 vs. 38.4 ± 2.7 weeks), preterm birth rate (12% vs. 20%), or birth weight (2939 ± 469 vs. 3019 ± 510 g).

CONCLUSIONS

We cannot state that an emergency surgery during pregnancy is rarely required for small benign ovarian cysts. However, the surgical outcomes were significantly better for elective than for emergency surgery, with no difference in perinatal outcomes. If a benign ovarian cyst is found early in pregnancy, elective laparoscopic surgery may be considered with adequate informed consent.

World Federation for Ultrasound in Medicine Review Paper: Incidental Findings during Obstetrical Ultrasound

Although the prevalence of incidental findings revealed during an obstetric ultrasound examination is low, the findings may include adnexal and cervical masses, uterine or urinary congenital malformations, free fluid in the pouch of Douglas or tortuous vessels (varices). Adnexal masses are the most common finding and vary in imaging characteristics. They are mainly unilateral, cystic masses with a low risk of malignancy that are treated conservatively. The International Ovarian Tumor Analysis scoring models may be helpful in differentiating benign from malignant masses. For those masses >5 cm, follow-up is recommended, and resection could be considered to avoid risk of torsion, rupture and hemorrhage, which may compromise pregnancy outcome. Uterine masses such as fibroids are commonly diagnosed early in the first trimester and should be followed up during pregnancy to evaluate any changes. Transabdominal and transvaginal ultrasound is the first-line test for the diagnosis of such incidentalomas; however, magnetic resonance ultrasound may have a useful role in excluding malignancy potential. As a result of their low frequency and the lack of good evidence, there are no specific guidelines on the management of incidentalomas detected at obstetric scans. Their management should follow the related general guidelines for ovarian, cervical and uterine masses, with individualized management depending on the pregnancy status.

Ultrasonographic evaluation of ovarian mass for predicting malignancy in pregnant women

OBJECTIVE

The purpose of this study is to compare ultrasonographic ovarian mass scoring systems in pregnant women.

STUDY DESIGN

This multicenter study included women with an ovarian mass during pregnancy who were evaluated using ultrasound and underwent surgery in 11 referral hospitals. The ovarian mass was evaluated and scored using three different scoring systems(International Ovarian Tumor Analysis Assessment of Different NEoplasias in the adnexa[IOTA ADNEX], Sassone, and Lerner). The final diagnosis was made histopathologically. Receiver operating characteristic(ROC) curves were generated for each scoring system.

RESULTS

During the study period, 236 pregnant women underwent surgery for an ovarian mass, including 223 women(94.5%) with a benign ovarian mass and 13 women(5.5%) with a malignant ovarian mass. Among 10 ultrasound image findings, six findings were different between benign and ovarian masses(maximal diameter of mass, maximal diameter of solid mass, wall thickness of mass, inner wall structure, thickness of septations, and papillarity). In all three scoring systems, the ovarian mass scores were significantly higher in malignant masses than in benign masses, with the highest area under the ROC curve(AUROC) in the Sassone scoring system(AUROC: 0.831 for Sassone, 0.710 for Lerner vs 0.709 for IOTA ADNEX; p < 0.05, between the Sassone and Lerner/ IOTA ADNEX). A combined model was developed with the six different ultrasound findings, and the AUROC of the combined model was 0.883(p = not significant between the combined model and Sassone).

CONCLUSION

In pregnant women, malignant ovarian tumors can be predicted with high accuracy using either the Sassone scoring system or the combined model.

Borderline serous tumor of the ovary discovered during pregnancy: A case report

Introduction

OFTs are tumors with low malignant potential. They represent 10 to 15% of all epithelial tumors of the ovary. Their mean age of occurrence is less than 10 years than that of carcinomas.

Case report

a 29-year-old female patient, second gesture, with no particular pathological history, consulted for pelvic pain occurring during a pregnancy of 8 SA + 5 days. The examination showed an abdominal-pelvic mass lateralized to the left with an enlarged uterus. Abdomino-pelvic ultrasound showed an evolving mono-fetal pregnancy of 10 weeks of amenorrhea, with two right and left latero-cystic solid formations measuring successively 4 × 4.3 cm and 8.99 × 8.25 cm. Pelvic MRI showed a left latero-uterine solid-cystic mass measuring 8.1 × 6.1 × 7 cm. An exploratory laparotomy was performed after the 16th week of amenorrhea revealed a left solid cystic ovarian mass of 10 cm. A left adnexectomy was performed with a right ovarian biopsy, peritoneal biopsy, epiploic biopsy and peritoneal cytology. The pathology report confirmed a borderline serous tumor of the left ovary on the left annexectomy specimen. The right ovary, epiploic and peritoneal biopsy is without tumor proliferation and the peritoneal fluid is acellular.

Discussion

OFT are characterized by their occurrence in women of childbearing age, with an increasingly advanced maternal age for the first pregnancy. Most adnexal masses are diagnosed during the first or second trimester and endovaginal ultrasound in the first trimester is the first-line examination for optimal characterization. Magnetic resonance imaging (MRI) is the recommended second-line examination from 12 weeks of age, in the presence of complex or indeterminate lesions that may be sufficient to distinguish OFMT. Surgical exploration of radiologically highly suspicious adnexal masses during pregnancy is indicated after 15 weeks of amenorrhea, to reduce the risk of miscarriage by alteration of the luteal function of the cyst in the first trimester.

Conclusion

The occurrence of OFT remains rare during pregnancy, which justifies the exploration of any adnexal mass discovered in the peripartum period, for which imaging plays an indispensable role in orienting the diagnosis.

•

FTOs are tumors with low malignant potential. Their average age is 10 years younger than that of carcinomas and their appearance during pregnancy is probably related to the advanced age of the mother at the time of the first pregnancy.

•

Pelvic ultrasound is the first-line examination for the diagnosis and evaluation of OFL during pregnancy, in the 1st or 2nd trimester, and magnetic resonance imaging (MRI) is the recommended second-line examination from 12 weeks of gestation.

•

L'exploration chirurgicale des masses annexielles radiologiquement suspectes pendant la grossesse est indiquée après 15 SA pour réduire le risque de fausse couche due à l'altération de la fonction lutéale du kyste au cours du 1ier trimestre.

•

The histological nature of the cyst is comparable to that encountered outside pregnancy, with a predominance of serous tumors.

•

The type of surgical treatment depends on the desire for pregnancy, the bilateral nature of the tumour and the criteria for aggressiveness, which could explain unilateral adnexectomy during pregnancy in the case of unilateral tfo with staging surgery.

Ovarian cyst elevation using a metreurynter for laparoscopic cystectomy of a benign ovarian cyst during pregnancy

BACKGROUND

A uterine manipulator cannot be used to elevate the ovary in benign ovarian surgery during pregnancy. This report describes our method of elevation of the ovary using a metreurynter with the success rate of the procedure and a comparison of surgical results and pregnancy outcomes between the successful and unsuccessful cases.

METHODS

Between August 2003 and February 2020, 11 pregnant patients with a tumor found sunk in the Cul-de-sac underwent laparoscopic cystectomy for a benign ovarian cyst with a metreurynter. The surgical results, success and failure of the elevation by a metreurynter, pregnancy outcomes, and fetal status at delivery were evaluated.

RESULTS

Elevation of ovarian tumors with a metreurynter was successful in nine cases. However, it was unsuccessful in the remaining two cases wherein the ovary was lifted with forceps while the uterus was in a compressed state. The operative time was also longer in these cases. The pregnancy prognosis, however, was good for both, successful and unsuccessful cases.

CONCLUSIONS

The metreurynter is an inexpensive and practical obstetric device, and its optimal use allows the performance of a procedure with minimal burden on a pregnant uterus. Therefore, we recommend the appropriate use of this method to enable effective laparoscopic cystectomy of ovarian tumors during pregnancy.

Safety of transvaginal aspiration of cysts in pregnancies complicated with ovarian endometrioma

OBJECTIVES

Pregnancy complicated with ovarian endometrioma is a risk factor for preterm delivery and rupture or infection during pregnancy. This study aimed to clarify the effectiveness and safety of transvaginal aspiration during pregnancy for endometrioma diagnosed in the first trimester.

DESIGN

This retrospective observational study included 8 pregnant women with endometrioma who underwent transvaginal cyst aspiration at 12-14 weeks (aspiration group) between March 2011-March 2018 and 23 pregnant women with endometrioma who refused aspiration during the same period (observation group).

METHODS

Characteristics of patients were compared in both groups. Safety, feasability and complications of transvaginal cyst aspiration were reported. Complications and obstetrical outcomes were reported and compared in both groups.

RESULTS

The maximum cyst diameter was 8.9 ± 1.5 cm (mean ± standard deviation) in the aspiration group, which was significantly larger than that in the observation group (4.7 ± 0.2 cm). Four preterm deliveries (17.3%) occurred in the observation group and none in the aspiration group. The emergency cesarean section rate during delivery was 14.2% in the aspiration group and 43.7% in the observation group.

CONCLUSIONS

The aspiration group tended to have lower rate of preterm deliveries and emergency cesarean sections, suggesting that cyst aspiration could be an effective, minimally invasive, and safe management option for endometrioma during pregnancy.

Management of ovarian masses in pregnancy: patient selection for interventional treatment

OBJECTIVE

The management of pregnant women with an adnexal tumor is still challenging and in the literature few data are available. The aim of this study was to describe the management and outcome of patients with ovarian masses detected during pregnancy. As secondary aims, we evaluated the prevalence of malignancy in the International Ovarian Tumor Analysis (IOTA) morphological classes of ovarian masses diagnosed during pregnancy, and created an algorithm for the management of patients with adnexal masses during pregnancy.

METHODS

This was a retrospective single centered study including patients with adnexal masses detected at any trimester during pregnancy between January 2000 and December 2019. Clinical, ultrasound, surgical, and histological data were retrieved from medical records as well as information on management (ultrasound follow-up vs surgery). Indications for surgery were recorded in terms of suspicion of malignancy based on pattern recognition of the ultrasound examiner or on symptoms or prevention of complications, such as torsion, rupture, or obstacle to normal full-term pregnancy. All masses were described using IOTA terminology.

RESULTS

A total of 113 patients were selected for the analysis. Of these, 48 (42%) patients had surveillance and 65 (58%) patients underwent surgery (11 primary ovarian tumors, one recurrence of ovarian cancer, four metastases to the ovary, 20 borderline tumors, and 29 benign lesions). Indications for surgery were suspicious malignancy in 41/65 (63.1%) cases and symptoms or prevention of complications in 24/65 (36.9%) cases. All patients in the surveillance group showed no morphological changes of the ovarian lesions at 6 months after delivery. According to the IOTA ultrasound morphological category, the prevalence of malignancy was 0% (0/37) in the unilocular cyst group, 27% (4/15) in the multilocular group, 35% (11/31) in the unilocular solid group, 70% (14/20) in the multilocular solid group, and 70% (7/10) in the solid group. Neither obstetric nor neonatal complications were reported for patients in the surveillance group or in those with benign, borderline, or primary epithelial invasive histology. In contrast, two neonatal deaths were observed in patients with ovarian choriocarcinoma and ovarian metastases. Three of the four patients with ovarian metastases died after pregnancy.

CONCLUSIONS

IOTA ultrasound morphological classification seems useful in the characterization of ovarian masses during pregnancy. A clinical and morphological based algorithm for counseling patients has been designed.

Management of adnexal masses' torsion during pregnancy

With the increased use and quality of ultrasound in pregnancy, adnexal masses are being encountered with greater frequency. Most of the time such masses are asymptomatic. It can be discovered in an emergency. Surgical intervention may cause risks to the mother and her fetus, while observation without intervention may also lead to unfavorable complications, such as ovarian torsion or the development of a tumor. Therefore, the management requires a balance between the maternal and fetal risks. We report two cases of torsion of adnexal masses during pregnancy, and we provide a brief literature review on the management and prognosis of this condition in pregnancy.

Nonobstetrical Robotic-Assisted Laparoscopic Surgery in Pregnancy: A Systematic Literature Review

Urologic and gynecologic surgeons are the top utilizers of robotic surgery; however, nonobstetrical robotic-assisted laparoscopic surgery (RALS) in pregnant patients is infrequent. A systematic literature review was performed to ascertain the frequency, indication and complications of RALS in pregnancy. Results showed 38 pregnancies from eleven publications between 2008 and 2020. Five cases were for urologic indication and 33 for gynecologic indication. Minimal surgical alterations were required. Although no adverse maternal-fetal outcomes were reported, there are not enough cases published to determine safety. This review demonstrates the feasibility of RALS for the pregnant population in the hands of competent robotic surgeons.

Ovarian cysts in pregnancy: a narrative review

Most adnexal masses are benign, incidental findings of pregnancy which resolve spontaneously. They may present clinically due to haemorrhage, rupture, torsion and mass effect. Aetiological classification includes ovarian benign, ovarian malignant, non-ovarian, gynaecological, non-ovarian non-gynaecological and an additional subset of pathologies unique to pregnancy. Ultrasound is the first-line imaging modality for the evaluation of adnexal masses. This may be supplemented with magnetic resonance imaging. Tumour markers support evaluation of malignant potential, but interpretation of results in pregnancy is challenging. Surgical intervention requires consideration of gestation, lesion characteristics and presence of complications. Laparoscopy is preferred owing to shorter operative time, quicker recovery and resultant lower thrombotic risk. Post-viability, fetal wellbeing and assessment must be considered. Management of the pregnancy may include cardiotocography, steroids, non-teratogenic antibiotics and tocolytics. In rare cases, particularly related to malignancy, termination of pregnancy may be required to enable immediate management where there are concerns for maternal wellbeing.

Adnexal masses in pregnancy: an updated review on diagnosis and treatment

Adnexal masses are not common in pregnancy. They are often discovered incidentally during routine ultrasound examinations. In general, 24%-40% of the cases are benign tumors; up to 8% are malignant tumors. Adnexal masses are usually asymptomatic, but sometimes can be responsible for abdominal or pelvic pain. Transvaginal and transabdominal ultrasound is essential to define the morphology of pelvic masses and to distinguish between benign and malignant cases. Magnetic resonance imaging can be a complementary examination when ultrasound findings are equivocal and a useful additional examination to better define tissue planes and relations with other organs. Patient counseling can be challenging because there is no clear consensus on the management of adnexal masses during pregnancy. Treatment options consist of observational management (in case of asymptomatic women with reassuring instrumental findings) or surgery (via laparoscopy or laparotomy). Surgery can be offered as a primary tool when cancer is suspected or when acute complications such as ovarian torsion occur.

Battey's operation as a treatment for hysteria: a review of a series of cases in the nineteenth century

Ovarian resection as a treatment for hysteria, called 'Battey's operation' or 'normal ovariotomy', was performed in the nineteenth century. Battey later reported that the resected ovaries appeared to have 'cystic degeneration'. Currently, patients with acute neuropsychiatric symptoms are screened for teratomas for the differential diagnosis of anti-NMDA receptor encephalitis. There is now a hypothesis that ovarian lesions resulting in paraneoplastic encephalitis were among the patients who underwent Battey's operation. We identified 94 published cases of Battey's operation for neuropsychiatric symptoms in the late nineteenth century. Among 36 cases with detailed descriptions, we found 3 patients who showed acute onset neuropsychiatric symptoms with macropathological ovarian findings that were compatible with teratoma. They showed favourable prognoses after surgery and might have motivated the surgeons to perform the operation.

[Borderline Ovarian Tumours: CNGOF Guidelines for Clinical Practice - Pregnancy]

OBJECTIVE

To determine the place of imaging, tumour markers, type of treatment and surgical route, follow-up, delivery mode, and re-staging in case of BOT during pregnancy, in order to provide guidelines.

METHOD

A systematic bibliographical analysis on BOT during pregnancy was performed through a PUDMED search on articles published from 1990 to 2019 using keywords « borderline ovarian tumour and pregnancy ».

RESULTS

Pelvic ultrasound is the gold standard and first-line examination for the detection and characterization of adnexal masses during pregnancy (grade C). Pelvic MRI is recommended from 12 gestational weeks in case of indeterminate adnexal masses and should be concluded by a diagnostic score (grade C). Gadolinium injection should be minimized because of proven risk to the fetus and should be discussed on a case-by-case basis after patient information (grade C). In the absence of data in the literature, it is not possible to recommend the use of any tumour marker for the diagnosis of BOT during pregnancy. In case of a surgical treatment of BOT during pregnancy, there is insufficient evidence to recommend either a cystectomy or an oophorectomy. For BOT, the laparoscopic approach should be preferred during pregnancy if it is feasible (grade C). Surgical route and type of surgery should be chosen after taking into account the tumour size, the obstetrical term, and the subsequent desire for pregnancy, following discussion in a multidisciplinary meeting. In the absence of sufficient data in the literature, it is not possible to make any recommendation on the follow-up of a BOT suspected during pregnancy. There is not enough evidence in the literature to change obstetrical management for delivery in patients with BOT. In case of incomplete staging of a BOT treated during pregnancy, restaging can be discussed as for non-pregnant patients (grade C).

CONCLUSION

The diagnosis of BOT occurring during pregnancy remains rare despite systematic screening of adnexal masses in the first trimester of pregnancy and an increasing maternal age. There is limited data in the literature concerning the management of BOT during pregnancy. All decisions must be taken after discussion in a multidisciplinary meeting.

Diagnosis and management of a giant ovarian cyst in the gravid-puerperium period: a case report

BACKGROUND

Giant ovarian cyst is very rare in gravid-puerperium period. It is a cause of a maternal-fetal morbidity. We report a case of a giant benign ovarian cyst in gravid-puerperium period which was diagnosed and managed in a hospital of a low-resource country.

CASE PRESENTATION

Data were collected by historical review, clinical examination, laboratory investigations, imaging examination, and by histopathological study of the excised surgical specimen. It is the case of a 25-year-old woman who was third gravida and third para with unknown pathological history. After she had given birth through vagina, a giant ovarian cyst, unknown during pregnancy, was diagnosed. A left oophorectomy carrying the cyst was performed after laparotomy in Yalgado Ouedraogo University Hospital Center of Ouagadougou (Burkina Faso). The cyst was 42 cm long and weighed 19.7 kg. The histology of the operative specimen revealed serous cystadenoma of the ovary. The postoperative course was uneventful.

CONCLUSION

This case reports that vaginal delivery is possible with a giant ovarian cyst associated with pregnancy. Surgical management of the cyst can be performed in the postpartum with satisfaction.

Necrotized torsion of enormous bilateral borderline tumors in young patient

Borderline ovarian tumors, or tumors of low malignant potential, are neoplasms of good prognosis that affect mostly patients of reproductive age. They account for 15% of all epithelial ovarian neoplasms and they are managed with surgical cytoreduction. Conservative surgery may be considered in patients who desire fertility preservation. Here we report on a patient who presented with vague abdominal symptoms and was diagnosed with large bilateral borderline tumors, of 18 and 15 cm in size. She underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy and epiplectomy and received adjuvant chemotherapy. Borderline ovarian tumors are a pathologic entity the gynaecologist should be well acquainted with.

Benign pelvic masses masquerading as adnexal cancer during pregnancy on ultrasound: A retrospective study of 5 years

This study was conducted to investigate the sonographic characteristics of benign adnexal masses misdiagnosed as malignancy, and determine whether sonographic findings may help distinguish these lesions from malignant tumors during pregnancy at a single center. We herein present our experience with pregnant women with benign adnexal masses misdiagnosed as malignancy by ultrasound and operated on during pregnancy or after delivery. A total of 4 cases of benign pelvic masses were misdiagnosed as adnexal cancer over a 5-year period, including an ovarian theca cell tumor with luteinization, an obsolete ectopic pregnancy of fallopian tube, an ovarian mature teratoma with abundant nervous tissue and a uterine myoma with degeneration. The masses were characterized by abundant blood flow and heterogeneous echo on ultrasound. In conclusion, adnexal masses identified during pregnancy exhibiting abundant blood flow and heterogeneous echo may not represent malignancy, even in the presence of increased carbohydrate antigen 125 levels. In certain cases, benign adnexal masses may be initially misdiagnosed as malignant during pregnancy.

Minimally Invasive Management of Ovarian Cysts During Pregnancy Using Ethanol Sclerosis

Traditionally, the management of symptomatic ovarian cysts in pregnancy has been limited to laparoscopy or laparotomy with the associated morbidity. However, in select patients requiring intervention, the risks of surgery may be minimized with sclerotherapy. We present the first case report, to our knowledge, of ethanol sclerosis of an ovarian cyst during pregnancy. A description of the surgical technique to complete such a procedure is provided as well as a brief review of the current literature with respect to the use of sclerotherapy for the management of ovarian cysts.
