Diagnostic Ultrasound - Abdomen and Pelvis
Endometrial Polyp (Left) Longitudinal transvaginal ultrasound shows focal nonspecific thickening of the endometrium ſt in a patient with dysfunctional uterine bleeding. The majority of the endometrium is atrophic, with a thin trilaminar appearance . (Right) Longitudinal transvaginal ultrasound during saline infusion in the same patient reveals an elongated pedunculated polyp ſt with a small stalk corresponding to the focal area of endometrial thickening. Diagnoses: Female Pelvis (Left) Longitudinal transvaginal ultrasound of the cervix shows a large polyp ſt prolapsing through the external os . Small internal cystic spaces are visible near the internal os. (Right) Sagittal T2-weighted MR in the same patient shows the polyp protruding through the cervical canal ſt. The polyp is hypointense relative to the normal endometrium , with the exception of internal cystic spaces . (Left) Longitudinal transvaginal ultrasound shows nonspecific focal thickening ſt in the upper endometrium, which could be secondary to hyperplasia, a polyp, or carcinoma. (Right) Longitudinal transvaginal ultrasound in the same patient following saline infusion reveals 2 sessile polyps ſt corresponding to the region of focal endometrial thickening. 759
Endometrial Polyp Diagnoses: Female Pelvis (Left) Longitudinal transvaginal ultrasound of the endometrium in a patient with menorrhagia shows a hyperechoic endometrial polyp with a hyperechoic line sign st. The endometrium is proliferative . (Right) Longitudinal transvaginal color Doppler ultrasound of the same polyp shows the vascular pedicle ſt with early branching. (Left) Longitudinal transvaginal ultrasound shows a cystic endometrial polyp ſt with a hyperechoic line sign st. (Right) Longitudinal transvaginal ultrasound of a patient with postmenopausal bleeding shows that the uterus is retroverted and contains a partially cystic endometrial polyp ſt. This was treated by D&C. (Left) Sagittal T2 HASTE MR demonstrates a thickened heterogenous endometrium with lower signal intensity from a polyp ſt. A small cyst in noted in the junctional zone st that is compatible with adenomyosis. (Right) Postcontrast fat-suppressed sagittal MR confirms the enhancing polyp ſt, which has internal cystic change st. 760
