Takeuchi M, Matsuzaki K, Harada M. Endometriosis, a common but enigmatic disease with many faces: current concept of pathophysiology, and diagnostic strategy. Jpn J Radiol 2024:10.1007/s11604-024-01569-5. [PMID: 38658503 DOI: 10.1007/s11604-024-01569-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Accepted: 04/06/2024] [Indexed: 04/26/2024]
Abstract
Endometriosis is a benign, common, but controversial disease due to its enigmatic etiopathogenesis and biological behavior. Recent studies suggest multiple genetic, and environmental factors may affect its onset and development. Genomic analysis revealed the presence of cancer-associated gene mutations, which may reflect the neoplastic aspect of endometriosis. The management has changed dramatically with the development of fertility-preserving, minimally invasive therapies. Diagnostic strategies based on these recent basic and clinical findings are reviewed. With a focus on the presentation of clinical cases, we discuss the imaging manifestations of endometriomas, deep endometriosis, less common site and rare site endometriosis, various complications, endometriosis-associated tumor-like lesions, and malignant transformation, with pathophysiologic conditions.

Noninvasive diagnostic imaging for endometriosis part 2: a systematic review of recent developments in magnetic resonance imaging, nuclear medicine and computed tomography. Fertil Steril 2024; 121:189-211. [PMID: 38110143 DOI: 10.1016/j.fertnstert.2023.12.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 12/13/2023] [Indexed: 12/20/2023]
Abstract
Endometriosis affects 1 in 9 women, taking 6.4 years to diagnose using conventional laparoscopy. Non-invasive imaging enables timelier diagnosis, reducing diagnostic delay, risk and expense of surgery. This review updates literature exploring the diagnostic value of specialist endometriosis magnetic resonance imaging (eMRI), nuclear medicine (NM) and computed tomography (CT). Searching after the 2016 IDEA consensus, 6192 publications were identified, with 27 studies focused on imaging for endometriosis. eMRI was the subject of 14 papers, NM and CT, 11, and artificial intelligence (AI) utilizing eMRI, 2. eMRI papers describe diagnostic accuracy for endometriosis, methodologies, and innovations. Advantages of eMRI include its: ability to diagnose endometriosis in those unable to tolerate transvaginal endometriosis ultrasound (eTVUS); a panoramic pelvic view, easy translation to surgical fields; identification of hyperintense iron in endometriotic lesions; and ability to identify super-pelvic lesions. Sequence standardization means eMRI is less operator-dependent than eTVUS, but higher costs limit its role to a secondary diagnostic modality. eMRI for deep and ovarian endometriosis has sensitivities of 91-93.5% and specificities of 86-87.5% making it reliable for surgical mapping and diagnosis. Superficial lesions too small for detection in larger capture sequences, means a negative eMRI doesn't exclude endometriosis. Combined with thin sequence capture and improved reader expertise, eMRI is poised for rapid adoption into clinical practice. NM labeling is diagnostically limited in absence of suitable unique marker for endometrial-like tissue. CT studies expose the reproductively aged to radiation. AI diagnostic tools, combining independent eMRI and eTVUS endometriosis markers, may result in powerful capability. Broader eMRI use, will optimize standards and protocols. Reporting systems correlating to surgical anatomy will facilitate interdisciplinary preoperative dialogues. eMRI endometriosis diagnosis should reduce repeat surgeries with mental and physical health benefits for patients. There is potential for early eMRI diagnoses to prevent chronic pain syndromes and protect fertility outcomes.

Abstract
BACKGROUND Polypoid endometriosis (PEM) is a rare and unique type of endometriosis. To date, no article has provided a systematic report of this disease. The current article provides a complete report on rare PEM based on ultrasound, magnetic resonance imaging, intraoperative findings and postoperative pathology data. CASE SUMMARY A 38-year-old female patient was admitted to our hospital after complaining of "vague pain in the right lower quadrant with an aggravated menstrual period for 8 mo". The patient underwent laparoscopic exploratory surgery on January 7, 2022. The postoperative pathology revealed extensive PEM. CONCLUSION PEM is a type of endometriosis that is a benign disease but has biological properties similar to malignant tumours.

Multimodality imaging findings of infected endometriomas: "T1 signal reversal" as a potential diagnostic sign? Radiol Case Rep 2023; 18:2452-2460. [PMID: 37235080 PMCID: PMC10206383 DOI: 10.1016/j.radcr.2023.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 04/10/2023] [Indexed: 05/28/2023] Open
Abstract
Endometrioma superinfection is a rare clinical entity that may cause diagnostic confusion and can be complicated by rupture, peritonitis, sepsis, and even death. Therefore, early diagnosis is crucial for appropriate patient management. Since clinical findings can be mild or nonspecific, radiological imaging is frequently used for diagnostic purposes. From a radiological perspective, it can be challenging to distinguish the presence of infection in an endometrioma. Complex cyst structure, wall thickening, increased peripheral vascularization, nondependent air bubbles, and surrounding inflammatory changes have been reported as potential US and CT findings suggestive of superinfection. On the other hand, there is a gap in the literature regarding MRI findings. To the best of our knowledge, this is the first case report in the literature to discuss MRI findings and temporal evolution of infected endometriomas. In this case report, we aim to present a patient with bilateral infected endometriomas at different stages, and to discuss the multimodality imaging findings, focusing specifically on the MRI. We defined 2 new MRI findings that may indicate the presence of superinfection in the early period. The first one was the "T1 signal reversal" seen in bilateral endometriomas. The second one, "progressive disappearance of T2 shading," was observed only in the right-sided lesion. These nonenhancing signal changes accompanied by increased lesion sizes during MRI follow-up were thought to represent a transition from blood to pus, and the percutaneous drainage of the right-sided endometrioma microbiologically confirmed our suspicion. In conclusion, MRI can be helpful in the early diagnosis of infected endometrioma due to its high soft tissue resolution. Percutaneous treatment may contribute to patient management as an alternative to surgical drainage.

T2*-Weighted Imaging Performance in the Detection of Deep Endometriosis among Readers with Different Experience: Comparison with Conventional MRI Sequences. Diagnostics (Basel) 2022; 12:diagnostics12071545. [PMID: 35885451 PMCID: PMC9315498 DOI: 10.3390/diagnostics12071545] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 06/17/2022] [Accepted: 06/22/2022] [Indexed: 11/30/2022] Open
Abstract
Magnetic resonance imaging (MRI) is an effective technique for the diagnosis and preoperative staging of deep infiltrative endometriosis (DIE). The usefulness of MRI sequences susceptible to chronic blood degradation products, such as T2*-weighted imaging, remains uncertain. The present study aims to evaluate the diagnostic performance of these sequences in addition to the conventional protocol for DIE assessment. Forty-four MRI examinations performed for clinical and/or ultrasound DIE suspicion were evaluated by three readers with variable experience in female imaging. The inter-observer agreement between the reader who analysed only the conventional protocol and the one who also considered T2*-weighted sequences was excellent. The less experienced reader diagnosed a significantly higher number of endometriosis foci on the T2*-weighted sequences compared with the most experienced observer. T2*-weighted sequences do not seem to provide significant added value in the evaluation of DIE, especially in less experienced readers. Furthermore, artifacts caused by undesirable sources of magnetic inhomogeneity may lead to overdiagnosis.
