Abstract:   (341 Views)
Background: Ovarian Malignant Müllerian Mixed Tumor (MMMT), also named ovarian carcinosarcoma (OCS), is a rare and aggressive biphasic malignancy with malignant epithelial and mesenchymal components. Advanced magnetic resonance imaging (MRI) techniques like quantitative T2 mapping enable non-invasive tissue microstructural assessment, their diagnostic value for ovarian MMMT requires further elucidation with clinical case evidence. Case presentation: A 78-year-old female presented with chronic constipation and a pelvic mass. Imaging revealed a large, heterogeneous pelvic mass with peritoneal and omental involvement. Quantitative MRI analysis revealed a T2 mapping value of 148±18 ms and a low apparent diffusion coefficient (ADC) value of 0.98±0.08×10-3 mm2/s. Histopathological examination confirmed ovarian MMMT with heterologous chondrosarcoma components. Conclusion: This case demonstrates that quantitative MRI parameters, especially T2 mapping, can reflect the high-grade malignant microstructural features of ovarian MMMT. T2 mapping serves as a valuable non-invasive biomarker for characterizing this rare gynecological malignancy, potentially aiding in the differentiation of benign and malignant ovarian lesions and assessment of tumor aggressiveness.
Keywords: Ovarian malignant Müllerianmixed tumor, carcinosarcoma, magnetic resonance imaging, t2 mapping, apparent diffusion coefficient.
