Cysts in pregnancy discovered by sonography

Abstract

The incidence of cysts in pregnancy was established with ultrasound. In 3,330 pregnant patients who underwent sonography, 38 adnexal cystic lesions (1.14%) were found. All but two cysts were discovered before 16 weeks. Follow-up showed that the majority of the cystic lesions resolved spontaneously; these were presumed to represent corpus luteum cysts. Five patients underwent surgery because of persistent cystic lesions; a mucinous cystadenoma, a benign cystic teratoma, a paraovarian cyst, an inclusion cyst, and a tuboovarian abscess were found. Septations and echogenic material were seen within the cystic teratoma and the tuboovarian abscess but the sonographic features of the other operated lesions were identical to those seen in the corpus luteum cysts.

Ovarian tumours associated with pregnancy: a five year retrospective study in a tertiary care hospital

“…[4][5][6][7][8][9][10][11] This large variation is due to differences in the definition of clinically significant masses. In our study, we chose to review only cases where the mass was 5 cm or greater in size.…”

Unclassified tumor of the gonadal stroma in a pregnant woman

“…Adnexal masses have been noted to occur in up to 1% of all gestations [5]. Gross and microscopic examination to exclude a malignant neoplasm is an indication for operative intervention.…”

“…The reported incidence of ovarian cancer in pregnancy ranges from 1:5,000 to 1:47,000 live births, with 2-6% of persistent adnexal masses being malignant [6,7]. Epithelial cancers and tumors with low malignant potential are the most common ovarian cancers found in pregnancy [5]. In a study of 36 cases of gonadal stromal tumors during pregnancy, there were only six cases of unclassified sex cord stromal tumors [8].…”
