[MRI Findings and Differential Diagnosis of Benign and Malignant Tumors of the Uterine Corpus]

Abstract

The uterus can be largely divided into the uterine corpus and uterine cervix. Diseases that can occur in the uterine corpus, composed of the endometrium and myometrium, vary from benign to malignant tumors. Ultrasound and CT are the primary non-invasive evaluation methods to differentiate between benign and malignant tumors, but in some cases, they are difficult to differentiate due to their non-specific imaging findings. However, magnetic resonance imaging (MRI), which has high resolution, helps not only in locating lesions but also in evaluating histological characteristics and staging of malignant tumors. In this review article, the characteristic MRI findings that radiologists should be aware of regarding various benign and malignant tumors detected in the uterine corpus are summarized with their points of differentiation.
