This paper/chapter describes adenomyosis as a cause of abnormal uterine bleeding, emphasizing that its pathogenesis and clinical manifestations vary and can be grouped into intrinsic, extrinsic, and intermediate types with different bleeding and pain patterns. It outlines that heavy menstrual flow and irregular bleeding can persist even during medical treatments such as LNG-IUS, GnRHa injections, or dienogest, and notes that intrinsic forms may show a clearer relationship to abnormal angiogenesis or other factors. The chapter states that MRI can support detailed classification of adenomyosis in cases with refractory bleeding and help delineate treatment options, but it does not provide original data or formal evidence synthesis within the text. Relevance to endometriosis: adenomyosis is discussed as a distinct cause of abnormal uterine bleeding with imaging and medical-therapy considerations, though the excerpt does not explicitly position it alongside endometriosis in the same way.

Abstract

The complex pathogenesis and different manifestations of adenomyosis make it a difficult cause of abnormal uterine bleeding to be diagnosed and treated. Adenomyosis can be divided generally into three types: intrinsic, extrinsic, and intermediate. Different types have different clinical presentations. In terms of intrinsic type, the cause of abnormal uterine bleeding is more obvious, and dysmenorrhea may not occur at the same time. It is because the abnormal uterine bleeding may be closely related to abnormal angiogenesis or other factors. The uterine bleeding is characterized by heavy menstrual flow and irregular bleeding, which is often encountered even during drug treatment, such as placing levonorgestrel-releasing intrauterine system (LNG-IUS) or GnRHa injection or taking dienogest. MRI can guide the detailed classification of adenomyosis with refractory bleeding and the treatment options.
