(c) Spot radiograph demonstrates an irregular mass-like filling defect in the fundus with small contrast material–filled diverticula, findings that represent focal adenomyosis. (d) Transabdominal US image shows thickening of the posterior uterine fundus with a heterogeneous echotexture in the area of focal adenomyosis (cf c).
