This paper is a narrative chapter defining endometriosis, describing its suggested prevalence, nonspecific symptoms with pelvic pain as the most common, and proposed etiologies such as retrograde menstruation and metaplasia. It outlines three endometriosis phenotypes (ovarian endometrioma, superficial peritoneal endometriosis, and deep infiltrative endometriosis) and notes wide variation in disease extent, and it discusses the role of laparoscopy alongside imaging modalities used to rule out other pelvic diseases and suggest endometriosis. A major limitation is that it provides an overview rather than original study data, and it does not establish diagnostic performance or standardized outcomes for any single imaging method. This paper is centrally about endometriosis — it provides a comprehensive description of disease phenotypes and the imaging-based diagnostic role in suspected cases.

Abstract

Endometriosis is the presence and growth of the glands and stroma of the lining of the uterus in an aberrant or heterotopic location. It is benign, but in many women, it is a progressive disease. The prevalence of endometriosis has been suggested to be 10% of women and is found predominantly in women of childbearing age. Symptoms of endometriosis are nonspecific, but the most common symptom is pelvic pain. The cause of endometriosis is uncertain and may involve retrograde menstruation, metaplasia. There are three phenotypes of endometriosis that include ovarian endometrioma, superficial peritoneal endometriosis, and deep infiltrative endometriosis (DIE). The extent of diseases varies considerably from isolated peritoneal lesions to widespread pelvic adhesions, infiltrating lesions, and ovarian cysts. Laparoscopy is only recommended in patients with negative imaging results and/or unsuccessful or inappropriate empirical treatment. However, a wide range of imaging modalities have gained a significant role in ruling out other pelvic diseases and may suggest the presence of endometriosis in the pelvis.
