Role of computed tomography in imaging of endometriosis
This review describes computed tomography findings of endometriosis in various organs, aiming to improve diagnosis by increasing awareness of these varied, often nonspecific, appearances.

This review examines the role of computed tomography (CT) in imaging endometriosis, focusing on common CT appearance patterns across pelvic organs. It outlines that while transvaginal ultrasound and MRI are the primary modalities for diagnosis and pre-surgical mapping, CT is often used as the first test in women with acute or nonspecific abdominal/pelvic pain, even though its CT findings are variable and nonspecific and can overlap with other pathologies. A key limitation emphasized is that endometriosis is frequently not suspected initially because CT features may not be distinctive, despite recognizable signs such as ovarian endometriomas, hemoperitoneum after rupture, uterine distortion, bowel bridging lesions, and urinary tract involvement. This paper is centrally about endometriosis — it specifically reviews abdominopelvic CT imaging findings and how CT can contribute to earlier diagnosis despite being a non-preferred modality.
