Sonographic diagnosis of paraovarian cysts: value of detecting a separate ipsilateral ovary.

A Giant Parovarian Cyst in a Dog with a Granulosa Cell Tumor

“…Ovarian cysts, such as ones arising from follicles or the corpus luteum, may have a similar appearance and can thus be misdiagnosed sonographically. When an ovarian cyst arises in the margin of the ovary, the remaining ovarian tissue can usually be observed along one margin of the cyst [12]. The remaining ovarian tissue near ovarian cysts with this location is crescentic in shape [12].…”

“…When an ovarian cyst arises in the margin of the ovary, the remaining ovarian tissue can usually be observed along one margin of the cyst [12]. The remaining ovarian tissue near ovarian cysts with this location is crescentic in shape [12]. However, in parovarian cyst the ipsilateral ovary is not affected and maintains its normal configuration, ovoid shape, because paraovarian cysts arise from the broad ligament between the uterine tube and ovary [3,8].…”

“…However, in parovarian cyst the ipsilateral ovary is not affected and maintains its normal configuration, ovoid shape, because paraovarian cysts arise from the broad ligament between the uterine tube and ovary [3,8]. Therefore, sonographic detection of ipsilateral ovaries separate from the cyst may be helpful for diagnosing paraovarian cysts [3,9,12]. A giant parovarian cyst can be confused with uterine lesions such as hydrometra, mucometra or pyometra because these lesions may appear as thin-walled tubular structures containing anechoic or echogenic fluid.…”

A rare case of successful pregnancy outcome with giant paraovarian cyst: a case report and review of literature

“…8 Paraovarian cysts are usually single, but bilateral lesions have been reported. 9,10 Diagnostic ultrasound (sonography) is a noninvasive diagnostic imaging technique which uses high-frequency sound waves to produce images of structures within the body. The sound waves are passed through the body tissues with a device called transducer.…”

Imaging in gynecology

“…Ultrasound morphology of various types of adnexal pathology is described in reference [74] and the diagnostic value of adding Doppler ultrasound to gray scale imaging is thoroughly discussed in reference [95]. The sensitivity and specificity of pattern recognition both with regard to malignancy and specific diagnoses are shown in Table 6 [94,[96][97][98][99][100][101][102][103][104][105][106][107][108][109]. A meta-analysis describing the diagnostic accuracy of transvaginal ultrasound specifically for the diagnosis of endometriomas has been published [110].…”
