Ethanol endometrioma sclerotherapy: safety through 8 years of experience.

STUDY QUESTION: What are the complications of transvaginal ethanol sclerotherapy for the treatment of endometriomas? SUMMARY ANSWER: Sclerotherapy is a reliable, minimally invasive method applicable in outpatient procedures but with specific and potential life-threatening complications that need to be identified and prevented. WHAT IS KNOWN ALREADY: There are currently few data on the use of transvaginal ethanol sclerotherapy, and we mainly note septic complications. STUDY DESIGN, SIZE, DURATION: A retrospective observational cohort study was carried out. The study was conducted at an academic hospital and included 126 women aged 31.9 ± 5.5 years (mean ± SD), between November 2013 and June 2021. We analyzed a total of 157 ethanol sclerotherapy treatment (EST), treated by 131 EST procedures, in 126 women. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included women with an indication for transvaginal ethanol sclerotherapy. Indications were women with at least one endometrioma over 10 mm, isolated or associated with other endometriosis locations, requiring treatment for pain or infertility before assisted reproductive treatment. We followed a standardized transvaginal ethanol sclerotherapy procedure consisting of an ultrasound-guided transvaginal puncture of one or more endometriomas under general anesthesia. The cyst content was completely removed and flushed with saline solution. Ethanol (96%) was injected at 60% of the initial volume of the endometrioma, remained in the cyst for 10 min and was then completely removed. Ethanol loss was defined as a loss of 5 ml or more than 10% of the initial volume of the injected ethanol. Failure was defined by the contraindication of endometrioma puncture because of interposition of the digestive tract, ethanol loss in the previous endometrioma treated (in case of multiple ESTs), failure to aspirate the endometriotic fluid, contraindication to start ethanol injection owing to saline solution leakage, or contraindication to continue ethanol injection owing to suspicions of ethanol leakage at sonography. Intraoperative complications were defined by ethanol loss, positive blood alcohol level, and ethanol intoxication. Postoperative complications were defined by fever, biological inflammatory syndrome, and ovarian abscess. Complications were classified according to the Clavien and Dindo surgical classification, which is a system for classifying postoperative complications in five grades of increasing severity. MAIN RESULTS AND THE ROLE OF CHANCE: We reported a total of 17/157 (10.8%) transvaginal ethanol sclerotherapy failures during 14/131 (10.7%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. In the same sets of data, complication was reported for 15/157 (9.5%) transvaginal ethanol sclerotherapy in 13/131 (9.9%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. Nine of 126 women (7.1%) had a grade I complication, one (0.8%) had a grade II complication (medical treatment for suspicion of pelvic infection), two (1.6%) had a grade III complication (ovarian abscess) and one (0.8%) had a grade IV complication (ethanol intoxication). We did not observe any grade V complications. LIMITATIONS, REASONS FOR CAUTION: This was a retrospective study and pain assessment not considered. The benefit-risk balance of endometrioma transvaginal ethanol sclerotherapy was not evaluated. WIDER IMPLICATIONS OF THE FINDINGS: Our study is the first to evaluate the complications of transvaginal ethanol sclerotherapy with such a large cohort of women in a standardized protocol. Transvaginal ethanol sclerotherapy seems to be an effective alternative to laparoscopic surgery in the management of endometriomas and limits the alteration of ovarian reserve. Transvaginal ethanol sclerotherapy is a reliable, minimally invasive method applicable on an outpatient basis. The majority of complications are Clavien-Dindo ≤IV, for which preventative measures, or at least early diagnosis and treatment, can be easily performed. The risk of ethanol intoxication is rare, but it is a life-threatening risk that must be avoided by appropriate implementation and promotion of the sclerotherapy procedures.

Rapid, free-breathing non-contrast MRI for first-line imaging evaluation of ovarian torsion in the emergency department.

BACKGROUND: Transabdominal ultrasound (US) is first-line imaging to evaluate ovaries in girls presenting to the emergency department (ED) with suspected ovarian torsion. Ovaries may be difficult to visualize sonographically; therefore, prompt diagnosis using US alone can be challenging. Rapid MRI as first-line imaging may help streamline patient throughput, especially with increasing MRI availability in the ED. OBJECTIVE: To assess feasibility of rapid MRI for diagnosis of ovarian torsion. MATERIALS AND METHODS: A retrospective, single-center IRB approved study of MRI performed in female pediatric patients presenting with abdominopelvic pain from August 2022 to January 2023. Imaging occurred according to one of three clinical pathways (US-first approach vs MRI-first approach vs US + MRI-second-line approach). A rapid three-sequence free-breathing MRI protocol was utilized. Frequency of ovarian torsion and secondary diagnoses was recorded. Length of MR scan time, time from ED arrival to time of diagnosis, and whether patient had US prior to MR exam were obtained. A historical cohort of patients with US only performed for assessment of ovarian torsion were evaluated for length of the US examination and time from ED arrival to time of diagnosis. Intervals were compared using the uncorrected Fisher's least significant difference and Turkey's multiple comparison tests. RESULTS: A total of 140 MRI exams (mean age 14.6 years) and 248 historical US exams (mean age 13.5 years) were included. Of the patients with MRI, 41 (29%) patients were imaged with US + MRI and 99 (71%) imaged with MRI only; 4% (6/140) MR exams were suspicious for ovarian torsion, with one true positive case (1/6 TP) and 5 false positive cases (5/6 FP); 26.4% (37/140) of exams had secondary diagnoses. Median MRI scan time was 11.4 min (4.4) vs median historical US scan time was 24.1 min (19.7) (P<0.001). Median time from arrival in ED to MRI read was 242 (140). Median time from arrival in ED to US only read was 268 min (148). This was not a statistically significant difference when compared to the MRI only cohort. CONCLUSION: First-line MRI imaging for evaluation of ovarian torsion is a rapid and feasible imaging modality for female patients in the emergent setting.

Fertility preserving management of ovarian torsion.

OBJECTIVE: To analyze characteristics of acute and chronic ovarian torsion, review treatment recommendations, and present possible surgical techniques for fertility preservation in young women. DESIGN: Literature review and demonstration of perioperative management of ovarian torsion using radiologic images and intraoperative video footage. Ovarian torsion is mostly mentioned in context of gynecologic emergencies, where acute ovarian torsion with arterial obstruction leads to ovarian ischemia and necrosis. However, ovarian torsion can also occur as a partial or intermittent torsion with venous and lymphatic obstruction, followed by ovarian swelling. In both cases, surgical management of ovarian torsion commonly includes oophorectomy, although leading guidelines recommend preservation of the ovary. We here aimed to raise awareness for the clinical features of ovarian torsion and demonstrate adequate perioperative management, thereby avoiding surgical overtreatment in young women. SETTING: Medical University of Vienna, Department of Obstetrics and Gynecology. PATIENT(S): We present a case of acute ovarian torsion with a consequently ischemic ovary as well as a case of chronic ovarian torsion with related massive ovarian edema. The patients included in this video gave consent for publication of the video and posting of the video online, including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.), and other applicable sites. INTERVENTION(S): Laparoscopic management with detorsion of the torquated ovaries, cystectomy on an ischemic ovary and oophoropexy to the pelvic side wall and utero-ovarian ligament to prevent recurrence. MAIN OUTCOME MEASURES: Postoperative relief of pain and normalization of ovarian size and morphology on ultrasound imaging. RESULTS: The current cases show successful conservative surgical management of ovarian torsion, hence preserving hormonal function and fertility in young women. CONCLUSION: Although it is recommended to preserve fertility in young women affected by ovarian torsion, surgical overtreatment by means of oophorectomy is still common in clinical routine. Increasing awareness for the clinical characteristics of acute and chronic ovarian torsion, as well as for the importance of preservation of the ovary, is crucial. We therefore believe that ovarian torsion and its surgical management deserve increased attention in the future.

Ovarian Clear Cell Carcinoma and Rectal Adenocarcinoma Detected by Tubo-Ovarian Abscess: A Case Report.

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital. Laparoscopic abscess drainage was performed, and pathological findings confirmed the presence of ovarian clear cell carcinoma inside the abscess. The tumor marker carcinoembryonic antigen (CEA) was elevated, and rectal cancer was diagnosed by a gastrointestinal endoscopy. Abdominal computed tomography (CT) showed a left adnexal abscess with an air image inside, and penetration of the abscess wall and rectal cancer were observed. Histopathologically, there was an accumulation of neutrophils around the rectal tumor cells. We concluded that the rectal cancer had penetrated the existing ovarian tumor and formed TOA. Non-gynecological diseases may be associated with TOA. It is necessary to consider the possibility that other clinical diseases may be associated with the trigger of TOA.

Scoring system for predicting ovarian necrosis in adnexal torsion using an ultra-short optimized MRI protocol.

PURPOSE: To evaluate a MRI scoring system predicting haemorrhagic necrosis in adnexal torsion with intraoperative and/or histopathological correlation using an abbreviated and optimized MRI protocol. METHODS: This retrospective observational study includes patients with adnexal torsion who underwent Magnetic Resonance Imaging(MRI) and surgery. T2 sequences were evaluated by three observers of varying experience for following findings: Hypo-intensity of ovarian stroma, around the follicle, cyst wall or ovarian capsule and the twisted pedicle. Hypo-intensities in the above and a thick cyst wall were considered as predictors of necrosis. A scoring system was created based on the number of positive findings. MRI was correlated with intraoperative and histopathological findings. Lesions showing haemorrhagic necrosis were considered true positives. RESULTS: 43 women with torsion were included. 74.4% were secondary to a lead point and 25.4% were without one. Hypointensity score of 2 or more had the highest diagnostic accuracy and inter-reader agreement in predicting necrosis (R1-sensitivity: 92%, specificity: 89%, positive predictive value (PPV): 92% and negative predictive value (NPV): 89%, R2-sensitivity: 92%, specificity: 94%, PPV: 96% and NPV: 90% and R3-sensitivity: 92%, specificity: 83%, PPV: 89% and NPV: 89%). CONCLUSION: In patients with suspected adnexal torsion, optimized MRI using T2 weighted sequences will serve as a rapid and effective single imaging modality for diagnosing adnexal torsion and accurately predicting necrosis thereby triaging the patients for appropriate management.

Sonographic Predictors of Ovarian Torsion in Premenarchal Girls.

STUDY OBJECTIVE: To identify preoperative transabdominal sonographic predictors of surgically confirmed ovarian torsion (OT) in premenarchal girls METHODS: We conducted a retrospective case-control study of 32 premenarchal girls aged 0-12 undergoing surgery for OT (cases) or a non-torsed ovarian mass (controls) from 2006 to 2017 at a single academic center. Cases had ICD-9/10 codes for torsion of the ovary, adnexa, ovarian pedicle, or fallopian tube and surgically confirmed OT; controls had codes for ovarian mass or cyst and surgically confirmed absence of OT. Preoperative transabdominal ultrasounds were analyzed by 3 radiologists blinded to final diagnosis. We used χ2, Fisher[s exact, and Student's t tests for statistical comparisons. RESULTS: From 2016 to 2017, 32 patients presented with acute abdominal pain or symptoms concerning for ovarian mass requiring ultrasound imaging and subsequent diagnostic laparoscopy; 24 (75.0%) had confirmed OT by laparoscopy, and 8 (25.0%) did not. The mean age in both groups was similar (7.3 ± 2.9 years). Preoperative sonographic variables significantly associated with OT included presence of a simple cyst (20.8% vs 12.5%), ovarian heterogeneity (100% vs 12.5%), presence of peripheralized follicles (70.8% vs 0%), and asymmetry of color Doppler (75.0% vs 37.5%; all P < .05). Presence of free fluid, arterial color Doppler, and a whirlpool sign were not predictive of OT. CONCLUSION: In premenarchal patients, although certain variables on transabdominal sonography predicted surgically confirmed OT, only the presence of peripheralized follicles was unique to girls with OT. The decision to proceed with diagnostic laparoscopy for suspected OT can be aided by these specific sonographic findings but should ultimately be based on high clinical suspicion.

Adnexal torsion: a review of diagnosis and management strategies.

PURPOSE OF REVIEW: Adnexal torsion remains a diagnostic challenge heavily reliant on high clinical suspicion, with patient presentation and imaging used as adjuncts to aid in its diagnosis. This review summarizes diagnostic and management techniques of adnexal torsion to assist providers when encountering this surgical emergency. RECENT FINDINGS: Common findings of adnexal torsion include abdominal pain, nausea, vomiting, and adnexal mass or ovarian enlargement. An elevated neutrophil to lymphocyte ratio may be useful for diagnosis. A 'whirlpool' sign, 'follicular ring' sign, enlarged/edematous ovary, and absent Doppler flow to the ovary are highly suggestive of adnexal torsion. Intraoperative visual diagnosis of ovarian death is highly inaccurate, with only 18-20% of ovaries necrotic on pathological examination. Necrotic appearing ovaries have been shown to have follicular activity on ultrasound one year postoperatively. SUMMARY: Pelvic ultrasound remains the first-line imaging modality. In patients of reproductive age, we recommend performing detorsion with ovarian conservation, even in cases where the tissue appears necrotic, given poor intraoperative diagnostic rates of tissue death. Retention of ovarian function is also reliant on a timely diagnosis and intervention. We emphasize that the risk of ovarian damage/loss outweigh the risk of a diagnostic laparoscopy in patients of reproductive age.

Pediatric Ovarian Torsion: Should You Go With the Flow?

OBJECTIVES: Ovarian torsion (OT) is an emergency that mandates early detection and surgical detorsion to avoid catastrophic consequences of further adnexal injury. Prompt ultrasound is critical for accurate diagnosis. Traditionally, evaluation of arterial and venous flow was used as a diagnostic tool for OT, but recent radiologic research has indicated that ovarian size and size discrepancy between sides is a better diagnostic criterion. This study seeks to determine whether ovarian size discrepancy or vascular flow to the ovary is more accurate in the diagnosis of OT in the pediatric emergency population and to better describe symptoms that distinguish OT from other abdominal and pelvic pathology. METHODS: This was a retrospective, cross-sectional study evaluating all female pediatric patients, aged 1 to 18 years, who underwent a pelvic ultrasound to evaluate for OT over a 2-year period in our pediatric emergency department. Patients suitable for inclusion were identified via Nuance mPowerTM, a search engine that provides clinical analytics based on radiology reports generated within our institution. RESULTS: We reviewed the medical records of 193 female patients aged 1 to 18 years, all of whom had a pelvic ultrasound (with or without Doppler) to evaluate for OT during the study period. In comparing ovarian size on ultrasound, patients with OT had a significantly larger magnitude of difference in ovarian volume than patients without torsion (5.57× [interquartile range, 3-12.5] vs 1.56× [interquartile range, 1.24-2.25; P < 0.001]). Ovarian torsion was associated with a 33-fold increased risk of lack of arterial flow (relative risk, 33.33) and with a 9-fold increased risk of lack of venous flow (relative risk, 9.27), when compared with those patients without OT. Patients with OT were significantly more likely to have emesis and peritoneal signs on examination, as well as previous history of OT (P = 0.01, 0.02, and 0.002, respectively) than those without OT. All patients with OT reported abdominal pain. CONCLUSIONS: We found that a large size discrepancy between ovaries is indicative of OT. Our data also suggest that presence of Doppler flow on ultrasound cannot be used to exclude OT but that lack of Doppler flow on ultrasound is a significant diagnostic marker. As previous studies have also found, clinical symptoms of OT are nonspecific and do not offer any certainty in differentiating OT from other pathologies.

Clinical and CT features of ovarian torsion in infants, children and adolescents.

OBJECTIVE: To investigate the clinical features and computed tomography (CT) findings of pediatric ovarian torsion. METHODS: A retrospective analysis of the clinical and CT data of 61 newborns, infants, children, and adolescents with ovarian torsion confirmed by histopathology was performed. RESULTS: Clinical features included abdominal mass, abdominal pain, nausea and vomiting, and fever. The tumor marker α-fetoprotein was increased in five cases. Ovarian enlargement was found in 26 cases, and follicles were detected in the peripheral region of the ovary in 21 cases. Twenty-one cases presented as solid mixed-density masses on CT images. A total of 30 cases of ovarian torsion were associated with a benign ovarian mass. Among 27 cases of cystic or predominantly cystic masses, the mass had a thickened wall in 26 cases and showed an uneven density in 23 cases. Among all 61 patients, a torsed pedicle was detected in 47 cases. A torsed ovary or mass exhibited mild contrast enhancement in seven cases. Uterine deviation toward the involved side, blurred fat space around lesions, and pelvic free fluid were also found. CONCLUSION: Pediatric ovarian torsion presents a relatively characteristic CT appearance. Correct diagnosis can be established based on clinical and imaging features.

Tubo-ovarian abscess: A proposed new scoring system to guide clinical management.

OBJECTIVE: To create a risk scoring system comprised of clinical and radiological characteristics that can predict the likelihood of antibiotic treatment failure of tubo-ovarian abscesses. The score should guide clinicians in identifying patients to whom early intervention should be offered instead of a prolonged trial of antibiotics. METHODS: A multicenter, retrospective cohort study carried out between January 1, 2013 and September 30, 2019, identified consecutive patients with tubo-ovarian abscess. Using a chronological split, patients were allocated to two groups for the development and subsequent validation of the postulated scoring system. Univariate and bivariate analyses were performed to identify statistically significant variables for the failure of intravenous antibiotic treatment. RESULTS: In total, 214 consecutive patients with tubo-ovarian abscesses were identified. Data from the first 150 patients were used for the development of the postulated scoring system; data from the subsequent 64 patients were used for validation. Statistically significant clinical features between those having successful and unsuccessful management were: temperature (median = 37.1℃ vs 38.2℃, P = 0.0001), C-reactive protein (151 mg/L vs 243 mg/L, P = 0.0001), and tubo-ovarian abscess diameter (6.0 cm vs 8.0 cm, P = 0.0001). These parameters were used to create a risk prediction score. A score of four or more was predictive of requiring surgical/radiological intervention of tubo-ovarian abscess (P < 0.001). The score had a sensitivity of 69% and a specificity of 88%, with area under the curve (AUC) = 0.859. CONCLUSION: Currently, there is no guidance for clinicians on when to operate on a tubo-ovarian abscess. Our prediction score is simple, using only three easily obtained clinical characteristics.

Prognostication of Ovarian Function after Ovarian Torsion Using Intraoperative Indocyanine Green Angiography.

STUDY OBJECTIVE: To quantitatively evaluate the blood flow in ovaries (ischemic ovaries) that underwent torsion using indocyanine green angiography (ICGA) and assess the use of ICGA as an indicator for functional preservation of the ovaries. DESIGN: In vivo animal study. SETTING: The University of Yamanashi Animal Experimentation Center. SUBJECTS: Eighteen female Wistar albino rats. INTERVENTIONS: As an alternative to ovarian torsion, we occluded an ovary in each rat for 24 hours, after which we performed ICGA before and after releasing ischemia and extracted the following 8 parameters: Fmax (maximum F value before releasing ischemia); Tmax (time taken from the onset of an increase in F to reaching Fmax); T½max (time taken from the onset of an increase in F to reaching half of Fmax); slope (Fmax/Tmax); time ratio (T½max/Tmax); F'max (maximum F value after releasing ischemia); reperfusion rate (F'max/Fmax); and reperfusion gap (F'max - Fmax). Four weeks later, we counted the total number of primordial and primary follicles and classified the rats into functional and nonfunctional groups. MEASUREMENTS AND MAIN RESULTS: On the basis of the total number of primordial and primary follicles, 13 rats had "functional" ovaries on the clamped side, and 5 rats had "nonfunctional" ovaries. The area under the curve values for each parameter were as follows: Fmax, 0.908; Tmax, 0.569; T½max, 0.546; time ratio, 0.746; slope, 0.877; F'max, 0.723; reperfusion rate, 0.938; and reperfusion gap, 0.862. CONCLUSION: ICGA can be used to quantitatively evaluate ovaries that have been subjected to ischemia, and the magnitude of fluorescence intensity can be an excellent predictor of ovarian necrosis. Quantifying the degree of reperfusion immediately after the release of ischemia can be an equally excellent predictor of necrosis.

Postoperative Ovarian Morphology on Ultrasound after Ovarian Torsion-Effect of Immediate Surgery: A Retrospective Cohort Study.

STUDY OBJECTIVE: Our objective was to determine if ovarian surgery at the time of ovarian detorsion is associated with impaired short-term ovarian function as indicated by ovarian morphology on ultrasound when compared with detorsion alone. DESIGN: Retrospective cohort study SETTING: The Hospital for Sick Children, Toronto PARTICIPANTS: Patients ≤ 18 years old with confirmed ovarian torsion from January 1, 2004, to December 31, 2018, with ovarian-sparing surgery. MAIN OUTCOME MEASURES: Data were collected on demographics, procedure, intraoperative findings, and postoperative ultrasound. To determine ovarian function, we compared the morphology on the postoperative ultrasound between those with surgery to the ovary and those without surgery to the ovary at the time of detorsion. We also compared the ovarian volume of affected and contralateral ovaries after detorsion and surgery to the affected ovary. RESULTS: One hundred and nineteen patients met the inclusion criteria, of whom 67 (56%) had detorsion with surgery to the ovary and 52 (44%) had detorsion alone. There was no statistically significant difference in appearance on the postoperative ultrasound between these groups (P =.446). There was also no statistically significant difference on the postoperative ultrasound of affected and contralateral ovarian volumes after detorsion and surgery to the affected ovary (P = .69). Patients who underwent surgery to the ovary experienced a lower rate of recurrence; however, this did not reach statistical significance, with a P value of 0.080. CONCLUSION: Our study demonstrates that surgery, eg cystectomy to the ovary at the time of ovarian detorsion, does not appear to impact ovarian function when compared with detorsion alone, as indicated on postoperative imaging. There was also no difference in volume of the affected and contralateral ovaries in those cases that underwent surgery at the time of initial detorsion. This evidence would support that immediate cystectomy at the time of initial ovarian detorsion is not associated with impaired ovarian function, thus avoiding the need for an interval cystectomy.

Prevalence of deep and ovarian endometriosis in early pregnancy: ultrasound diagnostic study.

OBJECTIVE: To assess the prevalence and morphological appearance of deep endometriosis and ovarian endometrioma using pelvic ultrasound examination in women attending for an early pregnancy assessment. METHODS: This was a prospective observational study set within a dedicated early pregnancy unit. The study included 1341 consecutive women who attended for an early pregnancy assessment for reassurance or because of suspected early pregnancy complications. All women underwent a transvaginal scan to assess the location and viability of their pregnancy. In addition, a detailed examination of pelvic organs was carried out to detect the presence of endometriosis and other gynecological abnormalities. Data analysis was performed using logistic regression and multivariable analysis. RESULTS: The prevalence of deep endometriosis and/or ovarian endometrioma in women attending our early pregnancy unit was 4.9% (95% CI, 3.8-6.2%). In 33/66 (50.0% (95% CI, 37.9-62.1%)) women with endometriosis, this was a new diagnosis that was made during their early pregnancy scan. On multivariable analysis, the presence of endometriosis was strongly associated with a history of subfertility (odds ratio (OR), 3.15 (95% CI, 1.63-6.07)) and presence of a congenital uterine anomaly (OR, 5.69 (95% CI, 2.17-14.9)) and uterine fibroids (OR, 2.37 (95% CI, 1.31-4.28)). Morphological changes typical of decidualization were seen in 11/33 (33.3% (95% CI, 17.2-49.4%)) women with ovarian endometrioma and 18/57 (31.6% (95% CI, 19.5-43.7%)) women with deep endometriotic nodules. CONCLUSIONS: Deep endometriosis and ovarian endometrioma were present in a significant proportion of women attending for early pregnancy assessment. The prevalence varied depending on a history of subfertility, and therefore is likely to differ significantly among populations, depending on their characteristics. Ultrasound is a useful tool for the detection of endometriosis in early pregnancy and the identification of women who may benefit from specialist antenatal care. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

Incidental Ovarian and Uterine Findings on Cross-sectional Imaging.

Incidental adnexal masses and uterine findings occur with a high frequency on cross-sectional imaging examinations, particularly in postmenopausal women in whom imaging is performed for a different reason. These incidentalomas encompass a gamut of potential pelvic gynecologic disorders. Most are benign ovarian cysts; however, other less commonly encountered disorders and improperly positioned gynecologic devices may be seen. A knowledge of the management recommendations for such pelvic incidental findings is critical to avoid unnecessary imaging and surgical interventions, as well as to avoid failure in diagnosis and management of some of these conditions.

Successful laparoscopic resection of ovarian abscess caused by Staphylococcus aureus in a 13-year-old girl: a case report and review of literature.

BACKGROUND: Ovarian abscesses, which occur mostly in sexually active women via recurrent salpingitis, occur rarely in virginal adolescent girls. Here, we present a case of an ovarian abscess in a virginal adolescent girl who was diagnosed and treated by laparoscopy. CASE PRESENTATION: A 13-year-old healthy girl presented with fever lasting for a month without abdominal pain. Computed tomography scan and magnetic resonance imaging indicated a right ovarian abscess. Laparoscopic surgery revealed a right ovarian abscess with intact uterus and fallopian tubes. The abscess was caused by Staphylococcus aureus. The patient recovered completely after excision of the abscess, followed by antibiotic treatment. CONCLUSIONS: Ovarian abscess may occur in virginal adolescent girls; Staphylococcus aureus, an uncommon species causing ovarian abscess, may cause the infection.
