Risk of torsion and malignancy by adnexal mass size in pregnant women

Abstract

Risks of torsion and malignancy are not directly proportional to increasing mass size in pregnant women. Physicians should be aware of a high risk of malignancy in women with an adnexal mass of over 15 cm. However, if a mass is smaller, the size should not be considered as a single independent factor in a decision for surgery.

Primary retroperitoneal mucinous cystadenocarcinoma during pregnancy

“…It has been recommended that masses larger than 5 -6 cm in diameter that persist past 16 weeks ' gestation and have indeterminate sonographic fi ndings, should be surgically removed (Hoover and Jenkins 2011). (b) More recently, Koo et al (2011) reported that the risk for malignancy associated with masses having a diameter Ͼ 15 cm was approximately 12-fold that of masses with a diameter Ͻ 6 cm. MRI revealed a cyst with solid mural nodules in our case.…”

Adnexal Mass during Pregnancy: A Review

“…Ã Abstracts may have contained information on both the surgical outcomes and ultrasound data, either one or the other, or not at all. [3][4][5][6][8][9][10][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] simple mass based on ultrasound, only 1% of these women had a malignant mass. The reported incidence of malignancy in pregnant women with an adnexal mass is 3.6 to 6.8%.…”

“…In our review, we found that the rate of torsion of adnexal masses in pregnancy is 10%. [3][4][5][6]10,[15][16][17][18][19][20][21][22][23][24][25][26][27] Most cases of torsion occurred in the first trimester and were histologically consistent with corpus luteum cysts. One study by Koo et al focused on the risk of torsion by the size of the adnexal mass.…”

Large malignant ovarian tumors during pregnancy: two cases

“…For mixed cysts larger than 5 cm, bilateral sides, or with nipple should be followed up with ultrasound; if it persists or the size increases by 30%–50%, surgical exploration is required 2,11,12. It has been reported that cysts larger than 15 cm are 12 times more likely to be malignant than cysts less than 6 cm in diameter 13. In the first case presented in this report, ultrasound revealed a solid mass larger than 10 cm, and blood flow suggested a malignant tumor.…”
