Malignant transformation of an endometriotic cyst: MDCT and MR findings DOI: https://doi.org/10.3941/jrcr.v5i1.435Keywords: endometriosis, endometriotic cyst, carcinoma, imaging, multidetector CT, magnetic resonanceAbstract Malignant transformation is a rare complication of endometriosis. MR criteria for diagnosis include the presence of soft-tissue components, enhanciment after contrast material administration in an endometriotic cyst. We present the multidetector CT and MR imaging findings in a case of an incidentally found endometrioid adenocarcinoma in a left-sided ovarian endometrioma, occurring in a 30-year old woman. MR imaging enabled the correct preoperative characterization of the lesion, by depicting a soft-tissue element, with strong and early enhancement after gadolinium administration. The same area had high signal intensity on diffusion-weighted images and low apparent diffusion coefficient values due to restricted diffusion, findings also strongly suggestive of malignancy.Downloads Published 2011-01-22 Issue Section Genitourinary Radiology License The publisher holds the copyright to the published articles and contents.
