This pictorial review illustrates the MRI findings of adenomyosis, a disease of the inner myometrium, and its associated conditions whilst focusing on their imaging pitfalls.

Teaching points:

• Adenomyosis is defined as the presence of ectopic endometrium within the myometrium.
• MRI is an accurate tool for the diagnosis of adenomyosis and associated conditions.
• Adenomyosis can be diffuse or focal.
• The most established MRI finding is thickening of junctional zone exceeding 12 mm.
• High-signal intensity myometrial foci on T2- or T1-weighted images are also characteristic.
