Fig. 1. 56-year-old woman undergoing tamoxifen therapy for 3 years
who had prior endometrial biopsy with negative findings. Sagittal
sonohysterogram reveals 3-cm endometrial polyp (calipers) and normal
endometrium. Polyp was confirmed at hysteroscopy.

Fig. 2B. 55-year-old woman undergoing tamoxifen treatment for 5 years.
Longitudinal sonohysterogram reveals circumferentially thickened endometrium
(solid arrows) measuring 12 mm and containing cystic areas. Catheter
(open arrows) is in cervix. Histopathology from hysteroscopy with
dilatation and curettage showed endometrial hyperplasia with atypia.

Fig. 3A. 77-year-old woman undergoing tamoxifen therapy for 2 years in
whom sonohysterography revealed endometrial polyp, but hysteroscopy was
negative for polyp and histopathology revealed benign endometrium. Transverse

and projecting into endometrial cavity.

Fig. 3B. 77-year-old woman undergoing tamoxifen therapy for 2 years in
whom sonohysterography revealed endometrial polyp, but hysteroscopy was
negative for polyp and histopathology revealed benign endometrium.
Longitudinal color power Doppler sonogram reveals feeding vessel
(arrow) that further supports diagnosis of endometrial polyp.

Fig. 4A. 63-year-old woman with tamoxifen who required no further
examination after sonohysterography revealed that apparent endometrial
thickening on transvaginal sonography was caused by subendometrial cysts.
Endometrium (arrows) appeared ill-defined, had cystic areas, and
measured 11 mm in thickness on sagittal transvaginal sonogram.

Fig. 4B. 63-year-old woman with tamoxifen who required no further
examination after sonohysterography revealed that apparent endometrial
thickening on transvaginal sonography was caused by subendometrial cysts. On
longitudinal sonohysterogram, endometrium (open arrows) appears
normal and subendometrial cyst (solid arrow) is seen.
