What is Ashermans syndrome, and what are its imaging characteristics?
Asherman’s syndrome is due to the presence of intrauterine adhesions or synechiae and is the result of endometrial trauma, such as from prior D&C, surgery, abortion, or infection. This is associated with infertility and secondary amenorrhea or hypomenorrhea. On sonohysterography, hyperechoic bands may be seen within the endometrial canal. On MRI, low T2-weighted signal intensity bands are seen in the endometrial canal, sometimes with distortion or obliteration of the endometrial cavity.
