This paper reviews anterior “deep endometriosis” localization patterns on MRI, contrasting atypical anterior pelvic sites with the more commonly described posterior deep endometriosis, with emphasis on parietal and inguinal involvement and deep lesions affecting the urinary system and anterior uterine supporting ligaments. It discusses the necessary MRI protocol adaptations to improve accurate diagnosis of deep anterior endometriosis and provides specific diagnostic criteria for each lesion type. A stated limitation is that the anterior categories are “arbitrary” groupings, which may constrain how findings map to clinical or anatomic classifications. This paper is centrally about endometriosis — it focuses on MRI features of anterior pelvic deep endometriosis.

Abstract

Many atypical locations for deep endometriosis exist that are not well known to both the radiologist and gynecologist. This work explores these unusual localizations, which we have arbitrarily grouped under the term "anterior endometriosis" in contrast to the more common posterior presentation of deep endometriosis that has been so well described in the literature. Parietal and inguinal involvement is first detailed, followed by a description of deep endometriosis involving the urinary system and anterior supporting ligaments of the uterus. A necessary adaptation to the MRI protocol in order to accurately diagnosis deep anterior endometriosis as well as specific diagnostic criteria for each type of lesion is reviewed.
