Objectives:

To establish characteristics of adenomyosis and its incidence, as well as to establish the link between adenomyosis with other imaging findings of women undergoing an MRI study by uterine myomatosis.

Material and methods:

The following study has an observational, descriptive, retrospective, and longitudinal. 50 MRI studies with the protocol for the location of fibroids were reviewed. Such studies were conducted between January 01, 2018, to December 31, 2019.

Results:

The average age was 38.72 ± 9.12 years with normal or parametric distribution according to the Kolmogórov-Smirnov test (p = 0.2). The lesson’s location was predominantly in the intramural (30%) and the intramural-subserous association (22%). The average injury size was 9.76 ± 4.44 mm. Of the 50 cases with a clinical diagnosis, only 11 (22%) were compatible with adenomyosis, for which there were 39 false positives. Microcysts were found in 15 patients (30%). No correlation was found between the size of the injury and its location (p = 0.193).

Conclusion:

MRI is a useful tool for discerning real adenomyomatosis injuries from those diagnosed by clinical diagnosis.
