Abstract:
MR imaging characteristics of adenomyosis were studied in nine women (five diffuse type, four focal type) who underwent hysterectomy. In all cases, MR images were correlated with surgical/pathologic findings. On T2-weighted images, diffuse type appeared as a thickening of the junctional zone, because it was often isointense with this zone. Focal type appeared as a low signal intensity, round or oval shaped mass poorly marginated from the adjacent myometrium.
