Figure 1. Adenomyoma. (a) Sagittal T₂ weighted (fast spin echo; 4000 ms repetition time and 88 ms echo time) and (b) transverse T₂ weighted (spin echo; 4000 ms repetition time and 80 ms echo time) images show a large posterior myometrial mass. The mass contains heterogeneous solid components (arrowhead) and is partly cystic (black arrow) with loculated air (curved arrow). The cystic component communicates directly with the endometrial cavity (open white arrow) and endocervical cavity. No fistula to bowel or bladder is seen.
