Advanced Carcinoma Endometrium in a Reproductive Age Group Woman: A Magnetic Resonance Imaging Diagnosis

Introduction: Endometrial adenocarcinoma, usually seen in postmenopausal women, can also occur in younger patients and is often associated with polycystic ovarian syndrome (PCOS) and obesity. Case Report: We report a case of a 33-year-old nulligravida woman with a 14-year history of subfertility, who presented with abdominal pain and a large abdominopelvic mass. While initial computed tomography (CT) imaging suggested ovarian malignancy, magnetic resonance imaging (MRI) revealed significant myometrial invasion, pointing to endometrial carcinoma. An endometrial biopsy confirmed grade 1 endometrioid adenocarcinoma, later staged as grade 2 stage 3 with positive pelvic lymph nodes after surgery. Discussion: Though clinical examination was suggestive of ovarian tumors, imaging helped in the diagnosis of endometrial cancer and further management. Conclusion: This case highlights the critical role of MRI in diagnosing endometrial carcinoma in younger women with atypical symptoms and underscores the importance of awareness among healthcare providers to suspect and appropriately investigate endometrial cancer in this population.
