Figure 3b. Posterior neofornix of the vagina. (a) Sagittal T2-weighted image shows an apparent posterior vaginal fornix (arrow). (b) Axial T2-weighted image shows the neofornix as an apparent mass posterior to the anastomosis (arrow). It is important to diagnose this finding as a normal variant of the surgical appearance and not as a recurrent mass lesion. This appearance was seen in 25 patients (56%).
