Intermenstrual bleeding secondary to cesarean scar diverticuli: report of three cases.
BACKGROUND
The differential diagnosis of intermenstrual bleeding includes structural lesions of the endometrium and cervix.


METHODS
Discrete diverticuli were noted in the endocervical canals of three women presenting with histories of multiple cesareans and chief complaints of intermenstrual bleeding. On ultrasound, diverticuli were diagnosed as cavities filled with heterogeneous material consistent with blood. In one case, the diverticulum was also visualized on hysterosalpingogram. Hysterectomy specimens in two cases showed diverticuli lined with fibrous tissue in previous uterine scars; in one case, this also contained endometrium.


CONCLUSIONS
Uterine scar diverticuli may cause intermenstrual bleeding in women with previous cesareans. When performing ultrasound in this clinical setting, physicians should look for these defects.
