Features considered important in diagnosing adenomyosis.
| Sign | Mode | Definition |
|---|---|---|
| Asymmetry of the anterior and posterior walls | 2D | A ratio above 1 |
| Enlarged globular‐shaped uterus with globular contour | 2D | Visual assessment; Exclude uterine contractions |
| Intramyometrial cysts | 2D | Round‐shaped lesions within the myometrium, with anechoic, low‐level echogenicity, ground‐glass appearance, or mixed echogenicity of intracystic content. Typically, there is a hyperechogenic rim surrounding the cyst |
| Hyperechogenic islands | 2D |
The presence of regular, irregular ill‐defined hyperechogenic areas within the myometrium |
| Fan‐shaped shadowing | 2D | Alternating hypoechogenic and hyperechogenic linear stripes crossing the uterine wall. |
| Hyperechogenic subendometrial lines or buds | 2D | Structures perpendicular to the endometrial cavity, but in continuum with the endometrium |
| Interrupted junctional zone | 3D | Best seen by rendering the coronal plane. May be irregular, interrupted, not visible, or measurable |
| Translesional vascularity’ | Doppler (Color/power) | Helps in differentiating between a myoma and adenomyosis, by the presence of circumferential flow in a myoma, against “translesional” flow |
