Pathogenesis and MRI findings in two cases of seromucinous borderline tumors coexisting with carcinoma in endometriotic cysts: Case reports and literature review
Seromucinous borderline tumors (SMBTs) generally have a favorable prognosis, and fertility-preserving surgery may be indicated. However, SMBT may occasionally coexist with carcinoma, necessitating careful management. This report presents two cases of SMBT coexisting with carcinoma within endometriotic cysts and reviews pathogenesis mechanisms with MRI-pathological correlations. In both cases, SMBT components appeared as papillary or nodular projections with prominent high signal intensity on T2WI, no diffusion restriction on DWI, and gradual, weak enhancement on dynamic contrast-enhanced (DCE) MRI. In contrast, coexisting carcinoma components showed intermediate signal intensity on T2WI, diffusion restriction on DWI, and rapid, intense enhancement on DCE-MRI. As it affects prognosis and treatment strategy, assessing the coexistence of carcinoma with SMBT is essential. This is the first report to demonstrate the usefulness of multiparametric MRI, including DWI and DCE-MRI, in evaluating SMBT and coexisting carcinoma in endometriotic cysts.
期刊介绍：
The Journal of Obstetrics and Gynaecology Research is the official Journal of the Asia and Oceania Federation of Obstetrics and Gynecology and of the Japan Society of Obstetrics and Gynecology, and aims to provide a medium for the publication of articles in the fields of obstetrics and gynecology.
The Journal publishes original research articles, case reports, review articles and letters to the editor. The Journal will give publication priority to original research articles over case reports. Accepted papers become the exclusive licence of the Journal. Manuscripts are peer reviewed by at least two referees and/or Associate Editors expert in the field of the submitted paper.
