Thirty-eight cases of paraovarian cysts in children and adolescents: a retrospective study.

PURPOSE: Paraovarian cysts in children and adolescents can be challenging to accurately diagnose prior to surgery. Our objective is to outline the clinical characteristics of paraovarian cysts and enhance the precision of diagnosing paraovarian cysts in this age group. METHODS: We retrospectively analyzed all patients with paraovarian cysts who underwent surgery in our department from 2013 to 2021. The review focused on demographic characteristics, clinical manifestations, intraoperative findings, and postoperative pathology of these patients. RESULTS: This cohort was composed of 38 children with paraovarian cysts. The average diameter of the cysts was 4.8 cm (range 0.5-10 cm). Among the cases, 25 (65.8%) had adnexal torsion. Postoperative pathology showed that all cases were simple cysts with serous fluid. After the procedure, the patients were monitored for a period ranging from 12 to 108 months. B-ultrasound and physical examination did not reveal any significant abnormalities. CONCLUSIONS: B-ultrasound can help diagnose paraovarian cysts by detecting slight deviation movement between the cyst and the uterus. The presence of adnexa torsion in children and adolescents with paraovarian cysts does not depend on BMI, but rather on the size of cysts. Laparoscopic cyst removal has proven to be an effective surgical approach with favorable outcomes.

Giant paratubal cyst: report of a case in second level public hospital.

BACKGROUND: Giant paratubal cysts are mostly benign tumors, with an incidence of 10%. The incidence rate of neoplasms is 2% to 3%, including papillary carcinoma and serous papillary neoplasms. CASE REPORT: A 35-year-old woman who began her current condition 3 years after her pregnancy, with urgency when urinating, abdominal pain and sensation of abdominal mass, who was diagnosed and protocolized in a second public level hospital of the State of Mexico, treated with open surgery, and good postoperative evolution.

ANTECEDENTES: Los quistes paratubáricos gigantes son en su mayoría tumores benignos, con una incidencia del 10%. La tasa de incidencia de neoplasias es del 2 al 3%, incluyendo carcinoma papilar y neoplasias papilares serosas. CASO CLÍNICO: Mujer de 35 años que comenzó su condición actual 3 años después de un embarazo, con urgencia al orinar, dolor abdominal y sensación de masa abdominal, que fue diagnosticada y protocolizada en un hospital público de segundo nivel del Estado de México, tratada con cirugía abierta y con buena evolución posoperatoria.

Non-Tender Huge Abdominal Mass in an Adolescent: Bilateral paraovarian cysts.

Paraovarian cysts constitute about 10% of all adnexal masses in females and occur most commonly in the third and fourth decades of life. These cysts are benign and usually uncommon in adolescence. Such cysts pose a diagnostic challenge while distinguishing them from ovarian cysts clinically and during radiological investigations. We report a rare case of a 13-year-old female patient with bilateral paraovarian cysts, including a giant cyst in right mesosalpinx presenting to Sohar hospital, Oman in 2018. The definitive origin of the huge mass on the right side of abdominal cavity could not be established in the current case despite contrast enhanced computerized tomography. It was only on laparoscopic exploration that this mass was identified as a giant paraovarian cyst. Both the giant cyst and a smaller paraovarian cyst on the left side were enucleated with minimally invasive surgery while preserving the fertility of the patient. Only one other similar case of bilateral paraovarian cysts in an adolescent, including a giant cyst managed with laparoscopy, has been documented previously.

Leiomyoma with Bizarre Nuclei (Symplastic Leiomyoma) in the Paratubal Cyst Wall: Report of a Rare Case.

Leiomyoma is a benign mesenchymal tumor that develops from smooth muscle cells. It can present in various histological variants. Leiomyoma with bizarre nuclei is an infrequent variant of uterine smooth muscle neoplasm. It is characterized by focally or diffusely distributed bizarre cells on the background of a typical leiomyoma. These bizarre cells are large, multinucleated, or multilobulated and have an eosinophilic cytoplasm. Even though leiomyomas with bizarre nuclei display benign clinical behavior, their differential diagnosis from leiomyosarcoma can sometimes be difficult. Leiomyoma has been described most commonly in the uterus. There is no case of leiomyoma originating from paratubal cysts described in the literature. In this article, we present a rare case of leiomyoma with bizarre nuclei originating from a paratubal cyst.

Torsión aislada de la trompa de Falopio, con necrosis de un quiste paratubárico: una urgencia ginecológica infrecuente / Isolated torsion of the Fallopian tube, with necrosis of a paratubal cyst: an infrequent gynecological emergency

INTRODUCCIÓN: La torsión aislada de la trompa de Falopio ocurre en aproximadamente una de cada 50.000 a 1.500.000 mujeres, por ende, es una afección extremadamente rara. Fue originalmente descrita por Bland-Sutton en 1890. El cuadro clínico suele ser inespecífico y puede simular una amplia variedad de dolencias. CASO CLÍNICO: Paciente de 18 años de edad que acude al servicio de urgencias por dolor abdominal intenso, la cual se decide ingresar por cuadro agudo doloroso abdominal de posible etiología ginecológica, se realiza laparoscopía de urgencia por la posibilidad de un cuadro de torsión quística, durante esta se observa una imagen laparoscópica de la trompa izquierda violácea y torcida, además un quiste paratubárico hemorrágico, de color violacio; por las características laparoscópicas de la trompa y el quiste paratubárico que se relacionan con necrosis de estos elementos, se decide realizar a la paciente una anexectomía total izquierda con cistectomía del quiste paratubárico. DISCUSIÓN: La rotación de la trompa alrededor de su pedículo vascular es el evento fisiopatológico descrito, lo que provoca inicialmente la obstrucción del retorno venoso y linfático, con el consiguiente edema, ingurgitación y trombosis. Si la torsión progresa, y no se resuelve, se ve comprometida la vascularización arterial y se desencadena la necrosis del órgano y, finalmente la instauración de peritonitis, la conducta se basa en la viabilidad de la trompa: si no tiene signos de necrosis, la conducta indicada es destorcerla, si ya aparecieron signos de necrosis deberá ser extirpada.

INTRODUCTION: Isolated torsion of the Fallopian tube occurs in approximately one in every 50,000 to 1,500,000 women, therefore, it is an extremely rare condition. It was originally described by Bland-Sutton in 1890. The clinical picture is usually nonspecific and can mimic a wide variety of ailments. CLINICAL CASE: An 18-year-old patient who came to the emergency service for intense abdominal pain, which was decided to enter due to acute abdominal pain of possible gynecological etiology, an emergency laparoscopy was performed due to the possibility of a cystic torsion condition, During this, a laparoscopic image of the violaceous and crooked left tube is observed, as well as, a hemorrhagic paratubal cyst, violet in color; Due to the laparoscopic characteristics of the tube and the paratubal cyst that are related to necrosis of these elements, it was decided to perform a total left adnexectomy with cystectomy of the paratubal cyst. DISCUSSION: Rotation of the tube around its vascular pedicle is the described pathophysiological event, which initially causes obstruction of venous and lymphatic return, with the consequent edema, engorgement and thrombosis. If the torsion progresses and does not resolve, the arterial vascularization is compromised and the necrosis of the organ is triggered and, finally, the establishment of peritonitis, the behavior is based on the viability of the tube: if there are no signs of necrosis, the indicated conduct is to untwist it, if signs of necrosis have already appeared, it must be removed.

Paraovarian Cyst Torsion in a Patient with Rubinstein-Taybi Syndrome: A Case Report.

Rubinstein-Taybi syndrome is an extremely rare autosomal dominant genetic disorder that occurs in 1/125,000 and is characterized by distinctive facial appearance, short stature, mild to severe mental retardation, and higher risk for cancer. In addition, variable organ anomalies had been reported. Paraovarian cyst causing torsion of the ipsilateral fallopian tube is less common, with an estimated incidence of 1/1,500,000, but it can adversely affect tubal function. It occurs mainly in women in the reproductive age and is very rare in prepubescent girls. Here, we described the successful treatment of an extremely rare case of paraovarian cyst causing torsion of the ipsilateral fallopian tube in a patient with Rubinstein-Taybi syndrome. A 14-year-old girl with Rubinstein-Taybi syndrome was referred to our hospital for abdominal pain. Her medical history was unremarkable, except for moderate hirsutism and keloid scar. Physical examination revealed tenderness in the lower abdominal midline. The preoperative diagnosis was torsion of a left ovarian cyst. An exploratory laparoscopy was performed because of acute abdominal pain and revealed a left fallopian tube that was twisted twice due to an ipsilateral paraovarian cyst. The huge paraovarian cyst required laparotomy cystectomy, and the left ovary was preserved. Her postoperative course was uncomplicated. Preoperative diagnosis of paraovarian cysts can be difficult. The moderate hirsutism seen in our patient suggested the presence of a large paraovarian cyst due to androgen receptor-mediated effects. Therefore, Rubinstein-Taybi syndrome patients with hirsutism should be screened and assessed by pediatric surgeons for the presence of paraovarian cysts.

Laparoscopic Management of Large Right Paratubal Cyst: A Case Report.

Paratubal cysts are generally small but there are rare cases of large paratubal cyst and this case is one of them. Here we report a case of a young female with complains of abdominal fullness since 3 months. On examination, a huge mass (25 x 25 cm) extending from symphysis pubis upto xiphisternum was noted. Ultrasongraphy showed a cystic mass of 27 x 27 cm. Intraoperatively, the cyst was paratubal. It was drained with the help of veress needle and laparoscopic cystectomy was done. A large adnexal cyst extending above umbilicus is traditionally managed by laparotomy. But with the advent of laparoscopy, even a huge cyst can be managed by laparoscopy.

Paratubal Cyst Recurrence in Children and Adolescents.

STUDY OBJECTIVE: To examine the association between patient characteristics and risk for recurrence risk of paratubal cysts (PTC) in children and adolescents. DESIGN: Retrospective chart review at a single institution. SETTING: Single academic children's hospital. PARTICIPANTS: Pediatric patients presenting to Texas Children's Hospital between July 2007 and March 2019. Patients were identified for the study by reviewing pathology reports and were included if they met inclusion criteria of a pathologic diagnosis of a paratubal or paraovarian cyst removed during any surgical procedure between July 2007 and March 2019. INTERVENTIONS: Subjects with pathologic diagnoses of a paratubal cyst during the study period underwent chart review for the following data points: age at presentation, ethnicity, pathologic recurrence of paratubal cysts, pubertal status, body mass index (BMI), diagnosis of polycystic ovary syndrome (PCOS), size of cyst, laterality of cysts, and number of cysts. MAIN OUTCOME MEASURE(S): Recurrence, Pathology types. RESULTS: Of the 627 patients that met inclusion criteria, the incidence of recurrence was 11.3%. Group 1 included those with recurrence of PTC (N = 70). Group 2 was identified as those without recurrence of PTC (N = 557). There were no differences related to age, BMI, ethnicity, history of PCOS, cyst size, laterality or number of cysts present. PTC NOS and serous PTC occurred most frequently. Of the unique cases involving recurrence, 70.1% recurred on the ipsilateral side. There were no cases of paratubal cyst malignancies in this cohort. The range of pathology diagnoses included pathologies that may occur in ovarian cysts. This is particularly interesting, given the known origins of ovarian cancer from fallopian tube transformations. Rare pathology diagnoses likely did not occur with frequency to determine definitive risks of recurrence in these cases. CONCLUSIONS: There appears to be a baseline recurrence risk for PTC, for which patients can be counseled. Recurrence does not appear to be associated with any particular pathology type, cyst size, number of cysts, BMI, PCOS, or puberty stage. Recurrence, should it occur, appears to occur more commonly on the ipsilateral side.

Magnetic resonance imaging and gasless laparoendoscopic single-site surgery for the diagnosis and management of isolated tubal torsion with a paratubal cyst at 31 weeks of gestation: A case report and literature review.

A 30-year-old nulliparous woman was transferred under suspicion of acute appendicitis, due to the sudden onset of severe right lower quadrant pain at 31 weeks and 4 days of gestation. Magnetic resonance imaging showed a cystic mass measuring 40 mm in diameter in the right lower abdomen. Because the right ovary without edematous swelling was noted adjacent to the cystic mass, isolated tubal torsion was strongly suspected. Emergency gasless laparoendoscopic single-site surgery showed isolated torsion of the right fallopian tube with a paratubal cyst. The right ovary was not involved in this torsion. Because the color tone of the distal portion of the fallopian tube did not recover sufficiently after detorsion, right salpingectomy was performed. Postoperatively, the infusion of magnesium sulfate was initiated due to increased uterine contraction and continued until 36 weeks of gestation. At 38 weeks and 1 day of gestation, uneventful vaginal delivery yielded a healthy female infant.

Giant Paratubal Serous Cystadenoma in an Adolescent Female: Case Report and Literature Review.

BACKGROUND: Paraovarian/paratubal cysts constitute 5-20% of all adnexal lesions and typically originate from the paramesonephric or Müllerian duct. The primary epithelial tumors arising from paraovarian cysts account for 25% of the cases, but giant cystadenomas of paraovarian origin are extremely uncommon during childhood and adolescence with very few cases reported in the literature. CASE: We present the case of a 15-year-old female that presented with a bulky mass in the abdomen and pelvis. An initial clinical and radiological examination indicated an ovarian cyst measuring ∼25 × 20 cm. However, explorative laparotomy revealed a giant paratubal cyst that was successfully treated with complete excision using fertility-sparing surgery. Histopathological examination was consistent with a serous cystadenoma. The postoperative course was uneventful and the girl was discharged on the seventh postoperative day. At the follow-up of 6 months, the patient was doing well.

An incidental diagnosis of a giant paraovarian cyst in a female teenager: A case report.

RATIONALE: Paraovarian cysts (PCs) are cystic tumors that can be encountered between the ovarian hilum and the ovarian fimbria located within the mesosalpinx and broad ligament, being usually diagnosed within the 3rd and 4th decade of life. PATIENT CONCERNS: We report the case of a 15-year-old female admitted in our clinic for consciousness loss, who was incidentally diagnosed with a giant pelvic cystic at ultrasound. DIAGNOSES: The magnetic resonance image showed a cystic mass of 170/140/85 mm, suggesting an origin from the left ovary, reaching the subhepatic area. INTERVENTIONS AND OUTCOMES: The surgical intervention revealed 3 PCs, a giant one and 2 smaller ones within the large ligament. The cysts were removed by laparoscopic approach, and the histologic examination did not reveal any signs of neoplasia. LESSONS: In addition to their rarity, giant PCs can be an incidental diagnosis in patients presenting unrelated symptoms resulting in increased difficulties related to the diagnosis. Moreover, the imagistic tools might not establish precisely the origin of these cysts, and therefore, the final diagnosis and treatment approach could be determined sometimes only during the surgical intervention.

Clinical Predictors of Isolated Tubal Torsion: A Case Series.

STUDY OBJECTIVE: A rare cause of adolescent abdominal pain includes isolated tubal torsion (ITT). Presentation is nonspecific and few studies have investigated ITT in adolescents. Our study objective was to describe the presentation and management of ITT in a large case series. DESIGN: Retrospective observational case series. SETTING: Tertiary care children's hospital. PARTICIPANTS: Participants were female and aged 3-21 years, presenting to Children's Hospital Colorado and diagnosed with ITT between January 2004 and August 2015. INTERVENTIONS AND MAIN OUTCOME MEASURES: Clinical presentation, physical exam, laboratory findings, surgical diagnosis, and treatment provided. RESULTS: A total of 19 cases were included. Average age was 13.3 (range, 11-18) years. In patients with unilateral abdominal pain (n = 16), there was 100% correlation with side of adnexal pathology. Ultrasound examination in 14 of 18 cases (78%) noted abnormal findings ipsilateral to the ITT. Most cases were managed with laparoscopy (84%; n = 16 of 19) and detorsion with or without cystectomy (74%; n = 14 of 19). Salpingectomy was more common with prolonged pain greater than 24 hours (relative risk 5.6, 95% confidence interval, 0.7-39.0). The most common intraoperative finding was a paratubal cyst (74%; n = 14 of 19). When Doppler flow was performed, it was present in 88% (n = 16 of 18) of the affected adnexa. ITT was more common on the left side (68%; n = 13 of 19). CONCLUSION: The high occurrence of paratubal cysts might suggest pathologic predisposition for ITT. Providers should maintain a high index of suspicion for ITT, particularly if associated with a paratubal cyst. Classic examination findings of surgical abdomen, leukocytosis, fever, and absence of Doppler flow are infrequently present. Laparoscopy and detorsion are appropriate treatments for managing ITT.

Paratubal Cyst Size Correlates With Obesity and Dysregulation of the Wnt Signaling Pathway.

STUDY OBJECTIVE: Paratubal cysts (PTCs) occur in 7%-10% of women, regardless of age. Although common, PTCs often are found incidentally because of the potential for these cysts to be asymptomatic. The specific aims of the study were to determine if PTC number and size correlated with signs of hyperandrogenism and obesity, as well as to investigate the molecular profiles of these PTCs in samples derived from female adolescents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: A prospective cohort study was performed in a single children's hospital. Girls 18 years of age or younger who underwent surgery for PTC suspected on the basis of the presence of a persistent adnexal cyst on imaging or a concern for adnexal torsion involving a cyst were consented to participate in the study. RESULTS: Nineteen patients met enrollment criteria with a mean age at menarche of 11.2 ± 1.3 years. Most of the patients (84%; n = 16/19) had adnexal torsion at the time of diagnosis of PTC. Irregular menses and hirsutism was found in 52.6% (n = 10/19) of the patients, among whom 36.8% (n = 7/19) were obese. The mean PTC size was 10.4 ± 4.3 cm with 57.9% (n = 11/19) of the cohort having more than 1 PTC. When patients were compared on the basis of their body mass index, the size of PTCs was significantly larger in the overweight/obese group. The wingless-type (WNT) signaling members catenin beta 1 (CTNBB1) and wingless-type MMTV integration site family, member 7A (WNT7A) were upregulated in 86% (n = 12/14) and 79% (n = 11/14) of the patients, respectively. WNT7A was significantly upregulated in girls with 1 cyst and low body mass index. CONCLUSION: A correlation exists between obesity, cyst size, and hyperandrogenism. Activation of the WNT/CTNBB1 pathway via WNT7A might play a role in PTC development.

[Adnexal torsion during the second trimester of pregnancy: about two cases]. / Torsion d'annexe au second trimestre de la grossesse, à propos de deux cas.

Acute pelvic pain during pregnancy makes the differential diagnosis more challenging. We here report two cases of adnexal torsion during the second trimester of pregnancy in order to draw attention to this diagnosis and to highlight the importance of early treatment to avoid irreversible damages due to ischemia which can be fertility-threatening. The first patient, G1P0, 20 weeks pregnant, initially presented with appendix syndrome. Exploration with a small McBurney incision showed a right ovarian necrosis, hence ovariectomy was performed. The postoperative course was uneventful. The second patient, G2P2, 26 weeks pregnant, presented to the emergency departments with acute left iliac fossa pain. Laparotomy revealed the torsion of a hydatid of Morgagni whose necrotic appearance due to twisting required hydatid ablation. No postoperative complications were noted in the two patients. Adnexal torsion is an emergency condition that should not be ignored in the case of acute pelvic pain in pregnant women. Conservative treatment represents the gold standard and proper management is necessary to avoid possible maternal and fetal complications.

Paratubal Borderline Malignancy: A Case of a 17-Year-Old Adolescent Female Treated with Laparo-Endoscopic Single-Site Surgery and a Review of the Literature.

BACKGROUND: Although paratubal cysts are common, borderline paratubal cysts are extremely rare. We describe the case of a large borderline paratubal cyst in a 17-year-old adolescent female treated with laparo-endoscopic single-site surgery (LESS), and review the literature. CASE: A 17-year-old female was referred due to a large right adnexal cyst on pelvic sonogram. A CT scan showed a 19-cm cystic lesion with enhancing papillary projection along the wall. Laparo-endoscopic single-site surgery confirmed a large cystic mass that originated from the right salpinx. Right salpingectomy and right ovarian wedge resection were performed, and intraoperative frozen section analysis was conducted. The result of the frozen section analysis and final pathologic review indicated that the cyst was a serous papillary-type borderline tumor in a paratubal cyst. SUMMARY AND CONCLUSION: To the best of our knowledge, this is the first case report of a BPC treated with LESS. We suggest that minimally invasive, fertility-preserving surgery should be considered as a standard treatment of borderline paratubal cysts if patients desire future fertility.

[Differential diagnosis of abdominal cysts in children]. / Hasi cysták és cystosus képletek differenciáldiagnózisa gyermekkorban.

19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients.

[Giant paraovarian cyst in childhood - Case report]. / Quiste paraovárico gigante en la infancia. Reporte de un caso.

INTRODUCTION: Paraovarian cysts are very uncommon in children OBJECTIVE: To present a case of giant paraovarian cyst case in a child and its management using a modified laparoscopic-assisted technique CASE REPORT: A 13-year-old patient with a 15 day-history of intermittent abdominal pain, located in the left hemiabdomen and associated with progressive increase in abdominal volume. Diagnostic imaging was inconclusive, describing a giant cystic formation that filled up the abdomen, but without specifying its origin. Laboratory tests and tumor markers were within normal range. Video-assisted transumbilical cystectomy, a modified laparoscopic procedure with diagnostic and therapeutic intent, was performed with a successful outcome. The histological study reported giant paraovarian cyst. Cytology results were negative for tumor cells. The patient remained asymptomatic during the postoperative follow-up. CONCLUSIONS: The video-assisted transumbilical cystectomy is a safe procedure and an excellent diagnostic and therapeutic alternative for the treatment of giant paraovarian cysts.

Giant Paratubal Cyst in Adolescence: Case Report, Modified Minimal Access Surgical Technique, and Literature Review.

BACKGROUND: Giant paratubal cysts are rare lesions that can present management challenges due to their enormous size. We present a modified minimally invasive approach for effective surgical management of giant paratubal cysts. CASE: A 19-year-old adolescent with worsening abdominal distention and metrorrhagia was diagnosed with a giant paratubal cyst. A modified, minimally invasive technique designed to limit spillage of cyst fluid was successfully used for surgical management. SUMMARY AND CONCLUSION: We evacuated 5500 mL of cyst fluid without spillage, and near-complete excision of cyst was performed with preservation of adnexa. Preservation of the adnexa in female adolescents is critical, and minimally invasive approaches should be used where possible.
