Abstract

Abstract
Background: Adenomyosis is defined as the presence of ectopic endometrial glands and stroma within the myometrium. It is a disease of the inner myometrium and results from infiltration of the basal endometrium into the underlying myometrium. Magnetic Resonance Imaging (MRI) is the radiologic tool of choice for this condition. A thickness of the junctional zone of at least 12mm is the most frequent MRI criterion in establishing the presence of adenomyosis.
Adenomyosis can appear as a diffuse or focal form. Adenomyosis is often associated with hormone-dependent lesions such as leiomyoma, deep pelvic endometriosis and endometrial hyperplasia/polyps.
Aim of Study: In this study we illustrate the role of MRI in evaluation of uterine adenomyosis, its findings and associ-ated conditions.
Patients and Methods: Thirty female patients were sus-pected to have uterine adenomyosis were enrolled for MRI using 1.5-T MR imaging unit. Patients were selected according to their age group (child bearing period), their clinical mani-festations, then later MRI findings for each case, collection of data then statistical analysis was performed.
Results: MRI for Uterine Adenomyosis is considered an accurate noninvasive modality for diagnosis of adenomyosis and associated lesions. Diagnostic sensitivity, specificity and accuracy of diagnosis of MRI were 92.3%, 75% and 90% respectively in our study.
Conclusion: Our study revealed that MRI represents an accurate evaluation tool for adenomyosis allowing its diagnosis and detection of associated pathologies and can differentiate it from mimicking lesions noted at other imaging modalities and planning of appropriate treatment.
