What differential considerations to be considered, based on transverse sonographic image?
Septate uterus and uterine adhesion band.
Considering the history and sonographic images, what would be the final diagnosis?
Uterine synechiae (Asherman's syndrome)
What other sonographic modality would be useful in such circumstances for better diagnosis?
3-D sonography would show the synechiae in all planes, and help in better approach.
What treatment should be considered?
Hysteroscopic lysis/excision of band is usually done in such cases.
A hypoechoic band (2 mm) is seen in midline in the endometrial canal, which appears to dissect or bifurcate the endometrial cavity, in the fundal region.
