Diagnostic Ultrasound - Abdomen and Pelvis
Abnormal Endometrium Pregnancy and Complications Pregnancy and Complications (Left) Sagittal US in a patient in the 1st trimester with a serum HCG > 260,000 mIU/mL shows marked expansion of the endometrial cavity with echogenic tissue and numerous tiny cysts ſt. Pathology was consistent with a partial mole. (Right) Transverse color Doppler US in the same patient shows increased blood flow within the trophoblastic tissue st. Differential Diagnoses: Female Pelvis Submucosal Leiomyoma Adenomyosis (Left) Longitudinal US shows a hypoechoic intracavitary submucosal leiomyoma st, well delineated by the echogenic endometrium ſt. Also note partial shadowing . (Right) Longitudinal US shows what appears to be a widened trilaminar endometrium; however, the echogenic line ſt represents the thin endometrium, with the poorly delineated hypoechoic regions secondary to adenomyosis. Endometrial Polyps Endometrial Polyps (Left) Transverse US shows nonspecific endometrial thickening ſt with an internal cyst st. (Right) Saline infusion sonohysterography in the same patient reveals a pedunculated endometrial polyp st as the etiology of thickening. 1051
Abnormal Endometrium Differential Diagnoses: Female Pelvis (Left) Longitudinal US shows nonspecific thickening of the endometrium ſt with heterogeneous echogenicity. Pathology revealed an endometrial polyp. (Right) Transverse US in a postmenopausal patient with bleeding shows a thickened endometrium ſt with small heterogeneous areas of increased blood flow st. Pathology revealed polyps as well as inactive endometrium. Endometrial Polyps Endometrial Polyps (Left) Transverse color Doppler US shows a thickened endometrium ſt with a single feeding vessel st, highly suggestive of an endometrial polyp. (Right) Additional imaging in the same patient shows fluid within the endometrial cavity surrounding the polyp st. Endometrial Polyps Endometrial Polyps (Left) Longitudinal US shows a thickened, slightly irregular endometrium ſt with internal cystic components st. Pathology was consistent with hyperplasia. (Right) Nonspecific thickening of the endometrium ſt is shown. Although the presence of a small cyst st is suggestive of a benign etiology, the importance of biopsy is emphasized as this was shown on pathology to represent endometrioid carcinoma.
