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.

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.

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.

Parovarian tumors of borderline malignancy.

The incidence of a parovarian tumor is 10-20% of all uterine adnexal masses, however, it is benign in most cases, and a borderline or malignant tumor is extremely rare. The classification of disease stage and treatment is still controversial owing to its scarcity. We have managed one mucinous and two serous cystadenomas of borderline malignancy originating from paraovarian cysts in our institute over ten year. We report and discuss the cases herein.

Paratubal borderline tumor diagnosed in the adolescent period: a case report and review of the literature.

BACKGROUND: Borderline paratubal cysts are rare entities. These tumors are identified as epithelial proliferation without stromal invasion. CASE: A 19-year-old virgin patient was admitted to our clinic with abdominal pain and nausea. The sonographic evaluation showed a left adnexal mass 89 × 80 mm in diameter with solid tissue projections. Doppler examination revealed no significant blood supply. At surgery, a torsed left paratubal cyst 10 cm in diameter and normal bilateral ovaries were encountered. Cystectomy was performed and of frozen section revealed a borderline Fallopian tube neoplasm. Final pathology review was reported as a serous borderline paratubal tumor. CONCLUSION: The evaluation of the structure of cyst by ultrasound and the performance of intraoperative frozen section analysis are two important issues to diagnose the nature of a cyst. Fertility-sparing surgery is the main point of management.

Quiste paraovárico complicado: causa rara de dolor abdominal / Complicated paraovarian cyst: rare cause of abdominal pain

: We report the ultrasonographic and laparoscopic findings in a case of twisted parovarian cyst related with a Morgagni hydatid, without involving of the tube and ovary. The 11 years old patient consulted for an acute abdominal pain that made suspect the clinical existence of acute appendicitis. The identification of normal appendix and ovaries, and the finding of a complex cyst structure close to the ovary, led to the laparoscopic surgery, that identified a twisted hydatid at the right side and a non twisted cystic structure at the left side. We discuss this pathology as an eventual and rare cause of acute abdominal pain in females.

Se presentan los hallazgos ultrasonográficos y laparoscópicos en un caso de quiste paraovárico torcido correspondiente a una hidátide de Morgagni sin compromiso de la trompa ni del ovario. La paciente de 11 años consultó, al servicio de urgencia por un dolor abdominal agudo que hizo plantear clínicamente la existencia de una apendicitis aguda. La identificación de un apéndice y ovarios normales, junto al hallazgo de una estructura quística compleja próxima al ovario llevaron a la cirugía laparoscópica que identificó la hidátide torcida a derecha y una estructura quística similar no torcida a izquierda. Se discute esta patología como una eventual y rara causa de dolor abdominal agudo en el sexo femenino.

Paratubal cyst: a case report.

Paratubal cyst can undergo torsion that can make it difficult to diagnose since tubal cysts mimic ovarian cysts. Most reported cases of paratubal cysts have occurred in pediatric patients, and this type of cyst rarely causes symptoms of lower abdominal pain mimicking appendicitis. We present the case of a 28-year-old female who was taking Carbergoline for hyperprolactinoma associated with a pituitary adenoma who came to the ER at Henry Ford Hospital in Detroit experiencing severe abdominal pain. Her pain was not accompanied by nausea, vomiting or other gastrointestinal symptoms. A transvaginal ultrasound revealed a normal uterus with the right ovary containing a cyst measuring 3 cm. x 2 cm. She was released on analgesics and seen at the clinic at Henry Ford Hospital three days later. She was still experiencing pain and was given antibiotics and Darvocet. When the pain had not subsided 48 hours later, a decision was made to perform diagnostic laparoscopy. Surgery was performed 10 days later and a paratubal cyst was removed that was twisted twice on its pedicle. This case illustrates the fact that torsion of paratubal cyst should be included in the differential diagnosis of adnexal pain.

Parovarian cystadenoma: sonographic features associated with magnetic resonance and histopathologic findings.

Differentiation between malignant and benign parovarian tumors is necessary before any surgery is planned, because the postoperative spread of ovarian cancers is well documented. Both malignant and benign parovarian tumors may contain intracystic projections, so their presence is not a differentiating factor. We describe the cases of 2 patients with parovarian cystadenomas that were evaluated using sonography, MRI, and histopathology in an attempt to begin to identify the sonographic characteristics of such lesions and correlate them with MRI and histopathologic findings. In both cases, sonography revealed a cystic mass that contained multiple small intracystic mural nodules, most of which were associated with the "Chinese hat" artifact. MRI findings confirmed the presence of the cystic masses and the nodules. Histopathologic findings confirmed the diagnosis of serous cystadenoma arising in a parovarian cyst; the intracystic nodules consisted of fibrotic tissue covered with a single layer of epithelium. Thus, the results of all 3 evaluations correlated well. This characteristic sonographic appearance may be useful in making an accurate preoperative diagnosis of parovarian cystadenomas.
