CT diagnosis of parovarian cyst / 实用放射学杂志

Objective To investigate the CT performances and causes of misdiagnosis of parovarian cyst,to improve its diagnostic accuracy.Methods CT data of 75 patients with surgically and pathologically confirmed parovarian cyst were analyzed retrospectively. Results Among the 75 patients,there were 79 cysts,in which 48 patients (51 cysts)originated from the epoophoron and 27 patients (28 cysts) from the mesosalpinx.77 were simple serous cysts and 2 serous cystadenomas.38 were located in the right ovarian adnexa,36 in the left ovarian adnexa,3 in the anterosuperior uterus,1 in the rectouterine pouch and 1 in the right iliac fossa.The size of the cysts ranged from 10 mm × 13 mm to 174 mm × 227 mm.75 were single cysts and 4 double cysts,34 presented as ovoid cysts,25 as irregular cysts, 17 as round cysts and 3 as gourd-shaped cysts.All the 79 cysts showed clear boundaries,thin walls,non-mural nodules,cystic fluid with a homogeneous densitywith CT value of 0-31 HU.Enhanced scanning revealed curved “obvious enhancement of the fallopian tube”at the edge of 68 cysts.In addition,the ipsilateral ovary could be detected in 76 cysts.“Holding ball”was found in 1 9 cysts.Conclusion Indication in ipsilateral ovary,curved “obvious enhancement of the fallopian tube”at the edge of cysts and “holding ball”are distinctive CT performances of parovarian cysts.CT has an important diagnostic value in parovarian cyst.

Ectopic Epididymis in Testicular Appendices: Report of Two Cases

We report two cases of ectopic epididymal ducts and efferent ductules in the testicular appendices (TAs) of adult men with normally descended testes. In both cases, a sessile TA was incidentally found at the upper pole of the right testis during the scrotal hydrocelectomy. Microscopically, a few closely arranged tubules were detected within the TA. In the first case, the tubules were lined with a pseudostratified columnar epithelium with numerous, long microvilli, and were surrounded by a smooth muscle coat. In contrast, in the second case, the tubules had a wavy luminal surface, because ciliated columnar cells alternated with groups of cuboidal cells. In both cases, strong CD10 immunoreactivity was observed in the luminal border of the lining epithelium. Surgical pathologists should be aware of the presence of both ectopic epididymal ducts and efferent ductules that can occur in TAs, in order to avoid misinterpretation as transected, functional reproductive structures.

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.

A case of parovarian tumor of borderline malignancy / 부인종양

Parovarian cysts, generally known as hydatid cysts of Morgagni, are small round cysts attached by a pedicle to the fimbriated end of the tube. Due to the rarity of this lesion, there are controversies concerning the origin, clinical behavior, treatment and prognosis of these tumors. Parovarian borderline malignancy mostly occur in young women, main complaints are abdominal enlargement and pelvic pain. we experienced one case of parovarian borderline malignancy and report this case with a brief review of literature.

Parovarian cyst torsion at pregnancy 29+4 wks / 대한산부인과학회지

Adnexal torsion in the third trimester is very rare. Because of changes in uterine size and anatomical position of abdominal organs, the diagnosis of adnexal torsion during pregnancy is difficult to establish on the basis of symptoms, physical findings, or radiologic technique. Delayed diagnosis and management can lead to serious complications, so a rapid, reliable, and accurate imaging is needed to evaluate pregnant women with acute abdomen. Ultrasonography has been the initial imaging modality of choice in evaluation of obstetric patient, but it is technically difficult in the third trimester. MR imaging can provide a broad evaluation of the pelvic organs and enables diagnosis of many causes of acute abdomen, especially in the third trimester. We have experienced a case of Parovarian cyst torsion at pregnancy 29+4 wks and reviewed it briefly.

A Case of Torsed Voluminous Parovarian Cyst / 대한산부인과학회잡지

Parovarian cysts constitute 10% of adnexal masses. They were found in broad ligament and mostly arise from mesothelium and less commonly from paramesonephric element and rarely from mesonephric element. In most cases parovarian cysts were asymptomatic. So, they were found incidentally at surgery for other conditions. Torsion is infrequent and it is difficult to distinguish it from torsion of other adnexal masses, appendicitis, etc. Recently, we experienced a voluminous parovarian cyst undergoing torsion, 25 cm in diameter. The case is presented with a review of literature.

A comparison between ultrasound-guided interventional therapy and open or laparoscopic therapy for paraovarian cysts / 中国微创外科杂志

Objective To study the feasibility of ultrasound-guided interventional therapy for parovarian cysts. Methods Diagnostic characteristics of 82 patients preoperatively diagnosed as having parovarian cysts were analyzed, and their clinical parameters were compared between 27 patients receiving ultrasound-guided interventional therapy and 55 patients receiving open or laparoscopic operations. Results Ultrasound examination was the principal means of diagnosis of parovarian cysts. The diagnostic accordance rate was 95.3% (82/86). The operative time, intraoperative blood loss and hospitalization costs in patients receiving ultrasound-guided intervention significantly decreased as compared with those receiving open or laparoscopic operation ( t =-20 798, 65 356, -184 533 , respectively; P =0 000). There were no significant differences in the postoperative recurrence rate and pyrexia rate between the two groups ( ? 2 =0 000, P =1 000; ? 2 =0 373, P =1 000). Conclusions Ultrasound-guided interventional therapy for parovarian cysts is feasible and offers satisfactory effects.
