Abstract

Ultrasound is an effective tool to detect and characterize endometriosis lesions. Variances in endometriosis lesions’ appearance and distorted anatomy secondary to adhesions and fibrosis present as major difficulties during the complete sonographic evaluation of pelvic endometriosis. Currently, differential diagnosis of endometriosis to distinguish it from other diseases represents the hardest challenge and affects subsequent treatment. Several gynecological and non-gynecological conditions can mimic deep-infiltrating endometriosis. For example, abdominopelvic endometriosis may present as atypical lesions by ultrasound. Here, we present an overview of benign and malignant diseases that may resemble endometriosis of the internal genitalia, bowels, bladder, ureter, peritoneum, retroperitoneum, as well as less common locations. An accurate diagnosis of endometriosis has significant clinical impact and is important for appropriate treatment.

Highlights

  • Endometriosis is a common, chronic, and debilitating gynecological condition that affects between5–15% of women within their reproductive ages [1,2]

  • Several studies have demonstrated the possibility of a diagnosis diagnosis (DD) of endometriosis lesions with benign [19,22,24,25,26] and malignant genital diseases [26,27]

  • The accuracy of ultrasound for the diagnosis of pelvic endometriosis has greatly improved the mucosal and/or muscular layers of the ureter [22,61]. It presents as a nodule along over recent years, and it is widely regarded as the first-line diagnostic tool, despite a significant the course of the ureter that causes a dilatation of the ureteral tract proximal to the stenosis

Summary

Introduction

Endometriosis is a common, chronic, and debilitating gynecological condition that affects between. It is characterized by the growth of tissue that mimics endometrial tissue and exhibits the same responses to hormonal changes [1] This abnormal tissue growth occurs outside the uterus, usually on other organs inside the pelvis and abdominal cavity, creating endometriosis implants. These endometriosis implants lead to local inflammatory reactions that promote fibrosis and adhesion formation, which create resistance between organs and may result in an altered pelvic anatomy [3]. The accuracy of the ultrasound in detecting deep-infiltrating endometriosis depends on the experience.
