Objectives: After studying the article entitled “Decidualized Endometriosis: Case Study of a Rare Condition in a Rare Location,” you will be able to:
Describe the typical findings associated with decidualized endometriosis
Describe the characteristic sonographic features of decidualized endometriosis
Differentiate decidualized endometriosis from other possible diagnoses
The most common benign tumors found in the uterus of women of childbearing age are Gestational trophoblastic disease Leiomyomas Leiomyosarcoma Mesothelioma
A sonographic characteristic of decidualized endometriosis is A uniformly hyperechoic lesion A very hypoechoic lesion A “ground-glass” appearance to the lesion A predominantly cystic mass with internal echogenicity
In the case presented, transvaginal sonography Established a definitive diagnosis Provided no additional data on the mass seen Was not able to be done Was not able to separate the mass from the cervix by probe manipulation
In the case presented, spectral Doppler data suggested a nonmalignant mass by Lack of high-velocity, low-resistance flow patterns Presence of very low-resistance flow patterns Presence of strongly pulsatility in the arterial flow patterns Lack of significant venous flow signals
Suspicion of endometrial carcinoma is elevated in postmenopausal women when sonographic measurements of the endometrium are >2 mm >5 mm >10 mm >15 mm
Differentiation of decidualized endometriosis from gestational trophoblastic disease can be made by evaluation of Endometrial thickness Endometrial vascularity Endometrial echogenicity Human chorionic gonadotrophin levels
Common differential diagnoses of decidualized endometriosis include all except
Leiomyoma Malignancy Germ cell tumor Gestational trophoblastic disease
A common feature of decidualized endometriosis that may make differential diagnosis difficult is Hyperechogenicity Rapid growth Lack of vascularity Irregular border margins
The endometrial changes associated with decidualization occur normally in the early stages of pregnancy because of Increased estrogen and progesterone Uterine growth Increased blood volume Elevated systemic pressure
The sensitivity of spectral Doppler measurement of the resistance index to document decidualized endometriosis has been reported to be variable and in the range of 10%–40% 40%–75% 50%–100% 80%–100%
