Figure 15b. Adenomyosis. (a) Sagittal T2-weighted image shows small foci of high signal intensity in the myometrium. (b) Sagittal T2-weighted image shows a widened junctional zone in the residual corpus uteri. Susceptibility artifact from the cerclage suture is also noted (arrow). Concurrent adenomyosis was seen in four patients (9%). These appearances were observed only after surgery.
