Synchronous Bilateral Ovarian Carcinomas With Right Mesonephric-like Adenocarcinoma and Left High-grade Serous Carcinoma: A Case Report and Review of the Literature.

Mesonephric-like adenocarcinomas (MLAs) are rare neoplasms of the uterus corpus and ovary, while high-grade serous carcinoma (HGSC) is the most common and lethal epithelial ovarian malignancy. We report a case of a 56-yr-old woman who presented with bilateral solid and cystic ovarian masses. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy, lymphadenectomy, omentectomy, and peritoneal biopsies. Histopathologic examination of the bilateral ovarian masses revealed 1 ovary with MLA, and the other ovary showed HGSC in association with serous tubal intraepithelial carcinoma. The morphology, immunophenotypes, and molecular profiling of the HGSC and the MLA were distinct and as expected for the different tumor types: HGSC was diffusely positive for WT-1, estrogen receptor, and p53 (mutant pattern), while negative for GATA-3 and TTF-1; MLA was positive for GATA-3 and TTF-1, while negative for WT1, estrogen receptor, and p53 (wild-type pattern); both tumors were diffusely positive for PAX-8. The HGSC revealed a TP53 c.659A>G (p.Y220C) mutation, and the MLA revealed a KRAS c. 34G>T (p. G12C) mutation and a PIK3CA c. 1034A>T (p. N345I) mutation. To the best of our knowledge, this is the first reported case of synchronous bilateral ovarian carcinomas with MLA and contralateral ovarian HGSC.

Cystic endometrial stromal sarcoma mimicking a cystic ovarian tumor : an unusual presentation

Low grade endometrial stromal sarcoma (LGESS) typically presents as a solid intracavitary or intramural uterine mass. On imaging, LGESS is usually seen as an endometrial or myometrial solid mass. Cystic change is unusal and may lead to a differential diagnosis of an ovarian mass as was seen in the present case. Here we present a case of a 38 year old woman who presented with a cystic ovarian mass clinically and radiologically. Per-operatively, it was found to be a multiloculated cystic mass, filled with serosanguinous fluid, in the uterine fundus. Histopathological examination showed a tumor mass composed of mainly spindle cells arranged in fascicular pattern showing marked myxoid degeneration and cystic areas. On immunohistochemistry(IHC), tumor cells showed positivity for CD 10, ER, PR, SMA and desmin while HMB45 was negative. Based on histopathological and IHC, a diagnosis of LGESS was made. Most cases of cystic uterine masses have a benign course but, LGESS exhibits a relatively poorer outcome and a risk of metastasis. Hence, we present this case for its unusual presentation which mimics an ovarian mass but has worse prognosis.

Lung adenocarcinoma metastatic to the ovary: a retrospective clinicopathological analysis of 17 cases and literature review

Lung adenocarcinoma metastatic to the ovary is rarely detected in clinical practice, and only a few cases have been reported. Its clinicopathological features, molecular genetics, and prognosis have not been well characterised. The data of 17 patients diagnosed with this disease between 2013 and 2022 were analysed retrospectively. All patients were non-smokers, with a median age of 46 years (range 30-71 years). Unilateral ovarian involvement was more frequent than bilateral involvement (58.8% vs 41.2%). Lesions presented as solid ovarian or mixed cystic and solid masses, and nearly two-thirds of the tumours (11/17, 64.7%) had a diameter greater than 10 cm. Solid adenocarcinoma was the most common histological subtype (9/17, 52.9%), and three of the cases showed abundant intracellular mucin and signet ring cells. Acinar adenocarcinoma was the second most common type (6/17, 35.3%), usually of moderate to poor differentiation. The remaining two cases were identified as micropapillary adenocarcinoma and mucinous adenocarcinoma. Multinodular growth, necrosis, and lymphovascular invasion were observed in half of the cases, and most of them had a marked stromal response. The most prevalent molecular alteration was ALK-rearranged (8/17, 47.1%), followed by EGFR gene mutations (5/17, 29.4%). A total of 34 cases, comprising 17 from the cohort and 17 from the literature, were included in the survival analysis. Patients with ALK-rearranged genes demonstrated an 80.0% 2-year overall survival rate, whereas those without ALK rearrangement exhibited a lower rate of 33.7%. Although there appears to be a potentially better prognosis for patients with ALK-rearranged genes, further cases and an extended follow-up period are necessary to substantiate this observation.

Pseudomyxoma peritonei leading to “jelly belly” abdomen: a case report and review of the literature

BackgroundPseudomyxoma peritonei is an infrequent condition with a global annual incidence of only one to two cases per million people. Mucinous neoplasms, widespread intraperitoneal implants, and mucinous ascites characterize it. Currently, most clinicians misdiagnose this condition, which leads to delayed management.Case presentationA 44-year-old North Indian female presented with a 1.5-month history of an abdominal lump. Physical examination revealed a sizeable abdominopelvic mass at 36 weeks. Contrast-enhanced computed tomography showed a massive multiloculated right ovarian cystic mass measuring 28 × 23 × 13 cm with mild ascites and elevated carcinoembryonic antigen levels (113.75 ng/ml). A provisional diagnosis of ovarian mucinous neoplasm was made, for which the patient underwent laparotomy. Intraoperatively, there were gross mucinous ascites, along with a large, circumscribed, ruptured right ovarian tumor filled with gelatinous material. The appendicular lump was also filled with mucinous material along with the omentum, ascending colon, right lateral aspect of the rectum, splenic surface, and small bowel mesentery. Cytoreductive surgery was performed along with an oncosurgeon, including total abdominal hysterectomy with bilateral salpingoophorectomy, omentectomy, right hemicolectomy, lower anterior resection, ileo-transverse stapled anastomosis with proximal ileal loop diversion stoma, excision of multiple peritoneal gelatinous implants, and peritoneal lavage. Histopathology and immunohistochemistry confirmed the presence of intestinal-type mucinous carcinoma. Postoperatively, the patient was given six cycles of chemotherapy. She tolerated it without any specific morbidity and had an uneventful recovery. Postoperative follow-up at 15 months revealed normal tumor marker levels and abdominal computed tomography findings and no signs suggestive of local recurrence or distal metastases.ConclusionsPseudomyxoma peritonei is a rare disease that is frequently misdiagnosed in the preoperative phase. Therefore, radiologists and clinicians should maintain a high index of suspicion for accurate diagnosis and multidisciplinary management.

A review of Radiological Imaging Features to ameliorate radiologists’ knowledge of Krukenberg Tumor (KT)

Object: Aim is to delineate the major radiological findings with US, CT and MR of the Krukenberg tumor. Method: Revision of the literature. Introduction: A Krukenberg tumor refers tipically to a gastrointestinal cancer that metastasizes to the ovaries; this tumor was named after Krukenberg, who originally described this pathologic condition of the ovaries in 1896. The prognosis of this tumor is uniformly poor.[1] Discussion: Krukenburg tumor (KT)is a metastatic malignancy of the ovary characterized by mucin-rich signet-ring adenocarcinoma that primarily arises from a gastrointestinal site in most cases and less commonly from other sites. Often these tumors are bilateral (over 80%), given their metastatic nature. The images of a Krukenberg tumor highlight that the masses are mostly: bilateral, lobulated, solid/mixed solid and cystic. Conclusion: On imaging, Krukenberg tumor should be suspected when bilateral solid, mixed solid and cystic, or predominantly cystic ovarian masses are seen in the presence of a known or suspected gastrointestinal primary malignancy. Krukenberg tumors should also be considered when a ovarian mass shows the so-called “lead vessel sign”[1-12-15].

A Rare Case of Ovarian Hydatid Cyst: A Must Consider Differential in Cystic Ovarian Masses Category: Case Report

A Rare Case of Ovarian Hydatid Cyst: A Must Consider Differential in Cystic Ovarian Masses Category: Case Report

An Unusual Cystic Lesion in Ovary

Introduction: Hydatid disease is a zoonosis caused by the larval stages or the adult of tapeworm Echinococcus granulosus or less commonly Echinococcus multilocularis. It is prevalent in the areas where livestock is raised in association with the dogs. Humans are accidental intermediate host. Primary ovarian hydatid cyst is extremely rare and often mistaken as cystic tumors of the ovary. Case report: We present a rare case of a 38 years old woman who presented with intermittent dull aching pain in the lower abdomen since 6 months. Ultrasonography of whole abdomen revealed the evidence of a left adnexal cystic lesion. Exploratory laparotomy was performed and a left ovarian cystic mass was identified. The cyst was removed intact. Histopathological examination confirmed it to be a hydatid cyst. Conclusion: Removal and proper treatment of the infected animals, interrupting the cycle of transmission of hydatid cyst, help to eliminate the disease. The implementation of public awareness of the disease and proper sanitation are needed to prevent this disease. Primary ovarian hydatid cyst is rare and requires proper intraoperative management to avoid spillage and thereby recurrences. Then the patients are treated with anthelmintics.

AYURVEDIC MANAGEMENT OF COMPLEX OVARIAN CYST- A CASE REPORT

Cysts in the ovaries can be simple or complex. Ovarian cysts classified as complexes include either blood or a solid material. In routine gynaecological practice, ovarian cystic masses are a prevalent concern. The prevalence of ovarian cysts varies greatly, according to data. According to reports, ovarian cysts affect 8–18% of women who are postmenopausal and premenopausal. The majority of the cysts are asymptomatic and are only found via standard ultrasonography. Some of them are very symptomatic, making it difficult for women to go about their daily lives. The size of the cysts has a significant impact on the symptoms. In modern times, therapy options include combined oral contraceptive pills and surgery to address cysts that don't go away after three months. Due to the numerous adverse effects of oral contraceptives, there is a growing need for other forms of management, particularly among patients who prefer not to undergo surgery. Ayurveda treats ovarian cysts under the general category of Granthi, where they are associated explicitly with Kaphaja Granthi. Treatment for an 18-year-old female patient who had a complicated left ovarian cyst with cystitis, dyspareunia, burning micturition, and significant lower abdominal pain was based on Ayurvedic principles. The patient was administered Srotosanghar Churn, Granthihar Kwath, Capsule Liv Fit, Search Cordial capsule, and Search Cordial syrup for one month. A follow-up USG revealed that the cyst had disappeared entirely, and the symptoms had decreased significantly. The current study highlights how Ayurveda can help control ovarian cysts beneficially.

Ayurvedic Approach for Management of (Hemorrhagic Ovarian Cyst) Andashayagata Raktaja Granthi – A Case Report

Ovarian cysts can be either simple or complicated. Complex ovarian cysts contain either a solid or blood component. A common worry in standard gynecological care is ovarian cystic masses. The findings show that there are wide variations in the prevalence of ovarian cysts. Reports state that 8–18% of post-menopausal and pre-menopausal women have ovarian cysts. Most cysts are asymptomatic and can only be detected by routine ultrasonography. Certain ones are very symptomatic, posing challenges for women in their day-to-day activities. The symptoms are significantly influenced by the size of the cysts. A closed, sac-like structure on or inside the ovary that is filled with a liquid or semi-solid material is called an ovarian cyst. A type of functional cyst known as a hemorrhagic cyst is often referred to as a corpus luteal cyst. Treatment options for cysts that do not go away after 3 months include surgery and a combination of oral contraceptive tablets. The need for alternative kinds of management is increasing as a result of the many adverse effects of oral contraceptives, especially for individuals who would rather not have surgery. Treatment for a 22-year-old female patient who had a complicated right ovarian hemorrhagic cyst with dyspareunia, burning micturition, and significant lower abdominal pain was based on Ayurvedic principles. For one and half months, the patient was administered Gandharva Hastadi Tail, Kachnara Gugglu, Arbudhara Kwatha katuki Churna, Chandanasava, Amrutoz, Dhatriloha, and Sankha Bhasm. A follow-up USG revealed that the hemorrhagic cyst had completely disappeared and that the symptoms had much decreased. The current study highlights how Ayurveda can help control ovarian cysts in a way that is beneficial.

Ovarian masses and pregnancy: About 2 cases and literature review (experience of Gyneco-obstetrics service 2 Fez)

Management of adnexal masses during pregnancy can be challenging for the patient and clinician. The specter of a possible malignant tumor may influence the decision to intervene rather than the expected management. The etiologies of ovarian masses vary depending on the age of the parturient, and therefore, benign entities such as functional ovarian cysts, benign cystic teratomas, and serous cystadenomas predominate. In cases of malignancy, these are generally germ cell tumors and borderline, low-grade ovarian tumors. Ultrasound is the primary modality used to detect ovarian masses and assess the risk of malignancy. Morphological criteria identify benign cysts more precisely than malignant tumors. Tumor markers are mainly used to monitor disease status after treatment rather than to establish the diagnosis of ovarian tumor due to lack of specificity, as several markers can be elevated by pregnancy itself (e.g. , CA-125, β-hCG). We report the cases of 2 patients who consulted the emergency room in a context of pelvic pain during pregnancy whose clinical examination aimed first to eliminate an emergency, notably a torsion of the adnexa, then to explore using ultrasound the etiology and characterize the objectified ovarian mass. The care is specific during pregnancy. Expectant management is recommended for most pregnant patients with asymptomatic, unsuspicious cystic ovarian masses. Surgical intervention during pregnancy is indicated for large and/or symptomatic tumors and those that appear highly suspicious for malignancy on imaging tests. The extent of surgery depends on the intraoperative diagnosis of a benign or malignant tumor. Conservative surgery is most often performed. More aggressive surgery is indicated for ovarian malignancies, including surgical staging. Although rarely necessary, chemotherapy has been used during pregnancy with minimal fetal toxicity in patients with advanced ovarian cancer, in which the risk of maternal mortality outweighs fetal consequences.

Abstract 12851: Severe Right and Left-Sided Multi-Valvular Carcinoid Heart Disease Associated With Ovarian Carcinoid Tumor

Carcinoid tumors are neuroendocrine neoplasms that secrete vasoactive substances, primarily serotonin, and have an incidence of approximately 2 in 100,000 people. Up to 60% of carcinoid tumors result in carcinoid heart disease (CHD), and unlike other carcinoid tumors, ovarian carcinoid tumors can involve the heart without liver metastasis. By bypassing the liver, ovarian carcinoid tumors can result in CHD in the absence of liver metastasis. We present a rare case of a 40-year-old female who presented in cardiogenic shock requiring inotropic support with echocardiographic evidence of preserved left ventricular systolic function (LVEF 50-55%) and multiple retracted leaflets that exhibited poor coaptation resulting in severe mitral regurgitation, torrential tricuspid regurgitation, and moderate-to-severe aortic regurgitation. Her left heart catheterization revealed non-obstructive coronary artery disease. A non-contrast CT torso revealed an isolated large septated left ovarian cystic mass (7.1x5.2 x7.1cm) without any other mass or lesion. In the setting of an elevated CA-125 (536units/mL, normal 0-35units/mL) and 24-hour urinary 5-HIAA (12.1mg, normal 2-9mg) with a normal CEA, CHD was suspected as the most likely diagnosis given the isolated ovarian mass and severe valvular disease. She underwent triple valve surgery in which valvular pathology revealed myxoid degeneration. Her post-operative course was complicated by multi-organ failure requiring multiple inotropes and V-A ECMO shortly thereafter, but the patient unfortunately passed away. While there are a few documented cases of CHD from ovarian carcinoid (less than 0.5% of cases) and left-sided CHD (less than 10% of cases), this is the first documented case, to our knowledge, describing severe right and left-sided CHD associated with a suspected ovarian carcinoid tumor.

FRI509 A Girl With Trisomy 21 Presents With Van Wyk-Grumbach Syndrome

Abstract Disclosure: J. Hayes dorado: None. M. Calla Ayala: None. A. Colque Arias: None. K. Lanuza Gaite: None. M. Rossell Lopez: None. D. Frias Eid: None. Van Wyc-Grumbach syndrome (VWGS) is a rare presentation of long standing prepubertal hypothyroidism characterized by bilateral multicystic enlarged ovaries, vaginal bleeding and delayed bone age. It appeared that high TSH could produce FSH and LH like activity leading to multiple ovarian cysts. A 7-year-old girl with trisomy 21, presented with vaginal bleeding for 2 days prior to admission. Physical exam revealed bradycardia (68 bbm), apathy, sluggishness, as well as dry skin and eyelid oedema. She had no breast development nor pubic hair.Causes of vaginal bleeding such as trauma, possible abuse, foreign body insertion and urethral prolapse were excluded. There was no purpura or bleeding from other sites.The abdominal sonogram revealed bilateral ovarian cystic masses (V:17.29 cm3 and 16.48 cm3, right and left, respectively). Bone age was delayed almost 3 years behind her chronological age. Laboratory tests revealed TSH 860 μIU/mL, T4 0.71 μg/dL, FSH 8.12 mIU/mL, LH < 0.1 mIU/mL, estradiol 193 pg/mL, thyroid peroxidase Abs 184 IU/mL, thyroglobulin Abs 212 IU/mL, Β-hCG < 0.1mU/mL, confirming severe hypothyroidism. The girl was diagnosed with VWGS due to unrecognized chronic lymphocytic thyroiditis and LT4 treatment (75mug/OD) was initiated. The patient responded with complete remission of symptoms and regression of the ovarian cysts one month after initiation of treatment. It is very important to think of VWGS and investigate for thyroid status during the evaluation of ovarian cysts or isolated premature menarche. Early recognition can eliminate unnecessary surgery to remove ovarian cysts, as appropriate treatment with levothyroxine leads to complete remission of symptoms. Even when the diagnosis of VWGS is confirmed, practitioners must be watchful to consider surgical intervention in the presence of uncontrolled vaginal bleeding, hemodynamic instability, or failure of regression of ovarian cysts with exogenous thyroid hormone replacement.

Bilateral ovarian mature teratoma in a middle aged female A rare entity

Mature cystic teratomas of ovary accounts for 10-20% of bilateral ovarian neoplasm. Majority of ovarian mature cystic teratomas are unilateral. Bilateral presentation accounts for only 10-15%. Our case is of 35year multiparous women presented with chief complaints of abdominal pain. Imaging methods like USG abdomen and pelvis, MRI revealed presence of bilateral cystic ovarian masses suggestive of bilateral teratomas. On gross examination showed bilateral cystically enlarged ovarian masses with abundant grey yellow pultaceous material, hair tuft and Rokitansky protuberance. Microscopically showed presence of ectodermal, mesodermal and endodermal elements in bilateral ovarian cysts.

Radiomics in the CT diagnosis of ovarian cystic malignancies - a pilot study.

The conventional computed tomography (CT) appearance of ovarian cystic masses is often insufficient to adequately differentiate between benign and malignant entities. This study aims to investigate whether texture analysis of the fluid component can augment the CT diagnosis of ovarian cystic tumors. Eighty-four patients with adnexal cystic lesions who underwent CT examinations were retrospectively included. All patients had a final diagnosis that was established by histological analysis in forty four cases. The texture features of the lesions content were extracted using dedicated software and further used for comparing benign and malignant lesions, primary tumors and metastases, malignant and borderline lesions, and benign and borderline lesions. Texture features' discriminatory ability was evaluated through univariate and receiver operating characteristics analysis and also by the use of the k-nearest-neighbor classifier. The univariate analysis showed statistically significant results when comparing benign and malignant lesions (the Difference Variance parameter, p=0.0074) and malignant and borderline tumors (the Correlation parameter, p=0.488). The highest accuracy (83.33%) was achieved by the classifier when discriminating primary tumors from ovarian metastases. Texture parameters were able to successfully discriminate between different types of ovarian cystic lesions based on their content, but it is not entirely clear whether these differences are a result of the physical properties of the fluids or their appartenance to a particular histopathological group. If further validated, radiomics can offer a rapid and non-invasive alternative in the diagnosis of ovarian cystic tumors.

Clear Cell Carcinoma of Ovary - Rare Subtype with Poor Prognosis: A Case Report

Ovarian clear cell carcinoma is a rare subtype of epithelial carcinoma of ovary having poor prognosis. This tumor has been found to be associated with endometriosis and has similarities with the pathogenesis of endometrioid carcinoma. We report a case of 37 years female presenting with the pain in right lower abdomen. Computerized Tomography revealed right ovarian cystic mass. Histopathology showed tubulocystic pattern of arrangement of tumor cells with few foci showing hobnail cells which confirmed the diagnosis. Keywords: Clear cell carcinoma, Ovary, Poor prognosis

Ovarian malignant melanoma metastasized from skin mimicking a benign cyst: a rare case report and mini-review of the literature

Malignant melanomas, often appearing on the skin, rarely metastasize to internal organs and the ovaries are the least affected site. A 45-year-old female patient presenting with a skin lesion on the right side of the neck and diagnosed with malignant melanoma through excision biopsy also appeared to have lung metastasis and a nonspecific ovarian cystic mass of 6 cm after PET-CT scan was performed. Examination revealed a mass with the widest diameter of 9 cm and a surgical decision was made due to the rapid growth pattern. Tumor markers appeared to be within the normal range. Laparoscopic right salpingoopherectomy was performed and frozen section biopsy was obtained. The result was found to be malignant and complementary surgery was performed. Pathological examination of the cystic mass, which was detected to have only nonspecific findings on radiological exam, revealed tiny solid areas in its capsule. The patient was started on postoperative Dabrafenib + Trametinib treatment by oncology and was followed up without recurrence until the 24th postoperative month. At month 24, the brain metastasis with no response to radiotherapy occurred and the patient was lost on the 15th day after decompression surgery. It is important to send adnexal masses to the frozen even if they appear to have a benign character. In patients with a known history of primary cancer, the possibility of the metastasis from the primary tumor site to the ovary should be considered in those whose peroperative frozen section result is in favor of malignancy. Our case is the first case of ovarian malignant melanoma metastasis with a completely cystic and septa-free character in the literature.

Mucinous tumors arising from ovarian teratomas as another source of pseudomyxoma peritoneii: MR findings comparison with ovarian metastases from appendiceal mucinous tumors.

The origin of pseudomyxoma peritoneii (PMP) has been established as low-grade appendiceal mucinous tumors (AMT). However, intestinal-type ovarian mucinous tumors are known as another source of PMP. Recently, it is advocated that ovarian mucinous tumors causing PMP originates from teratomas. However, AMTs are often too small to detect on imaging; then, differentiating metastatic ovarian tumors of AMT from ovarian teratoma-associated mucinous tumors (OTAMT) is important. Therefore, this study investigates the MR characteristics of OTAMT compared to the ovarian metastasis of AMT. MR findings of six pathologically confirmed OTAMT were retrospectively analyzed compared to ovarian metastases of low-grade appendiceal mucinous neoplasms (LAMN). We studied the existence of PMP, uni- or bilateral disease, the maximum diameter of ovarian masses, the number of loculi, a variety of sizes and signal intensity of each content, the existence of the solid part, fat, calcification within the mass, and appendiceal diameters. All the findings were statistically analyzed using the Mann-Whitney test. Four of the six OTAMT showed PMP. OTAMT showed unilateral disease, had a larger diameter, more frequent intratumoral fat, smaller appendiceal diameter than those in AMT, and they were statistically significant (p < .05). On the other hand, the number, variety of size, signal intensity of loculi, and the solid part, calcification within the mass did not differ from each other. Both OTAMT and ovarian metastasis of AMT appeared as multilocular cystic masses with relatively uniform signal and size of loculi. However, a larger unilateral disease with intratumoral fat and smaller size of the appendix may suggest OTAMT. OTAMT can be another source of PMP, as AMT. MR characteristics of OTAMT were very similar to ovarian metastases of AMT; however, in cases with PMP combined with fat-containing multilocular cystic ovarian mass, we can diagnose them as OTAMT, not PMP caused by AMT.

Postmenopausal woman with 24 kgs ovarian mucinous cystadenoma: a rare case report

A case of a 53-year-old postmenopausal woman presenting a giant ovarian cystic mucinous tumor weighing 24 kg is reported here. When she was seen first at our outpatient clinic, she had gross abdominal distension since 2 years, and she complained of unbearable aggressive pain. Her computed tomography (CT) scan was done which came suggestive of ovarian serous cystadenoma of large massive size 35 x 40 x 32 cm with moderate ascites. On exploratory laparotomy, a giant, totally cystic, vascularized and smooth mass attached to the right ovary was encountered. On the postoperative tenth day, she was discharged without any problem. Histopathology report of the right ovarian cystic mass came suggestive of multiloculated cyst with capsule intact with Borderline Mucinous tumor of right ovary weighing 24 kg. This is both one of the largest known examples in the literature and the largest ovarian cyst ever seen at our institution.

Pelvic Cystic Echinococcosus Causing Acute Renal Failure With Ureteral Compression: Case Report

Cystic Echinococcosis (CE) is a zoonosis that is endemic in Turkey and is caused by the contamination of eggs of the Echinococcus granulosus parasite. The liver is the most common organ affected up to 70-80%. On the other hand, pelvic CE is very rare and can often be confused with gynecological malignancies. It is more difficult to diagnose in older women. In this study, we aimed to present a 72-year-old female patient who was previously operated for the diagnosis of CE that is located in segment 6 of the right lobe of the liver. In the radiological examination of the patient, a lesion compatible with recurrent intra-abdominal CE or ovarian cystic mass was observed. The patient developed acute renal failure because of the compression of the ureter by the cystic mass in the pelvis. The patient underwent total cystectomy and hysterectomy by laparotomy. The patient was discharged on the 4th post-operative day with albendazole treatment. CE should be kept in mind in the differential diagnosis of intraabdominal cystic masses.
