[INTRODUCTION - Müllerian adenosarcoma is typically composed of benign glandular epithelial elements admixed with malignant sarcomatous stroma. This rare tumour usually originates in the endometrium and grows as a polypoid mass into the endometrial cavity. CASE REPORT - We report the case of a woman aged 32, who presented with abnormal vaginal bleeding and was diagnosed with an adenosarcoma after a curettage and subsequent hysterectomy. CONCLUSION - This tumour has a relatively good prognosis among the mixed mesenchymal sarcomas of the uterus and the majority of patients with this neoplasm survive. The gynecologists and pathologists should be aware of this entity and discuss the risks and benefits of radiation and chemotherapy, which is usually indicated for malignant diseases.]

[Magnetic resonance imaging (MRI) is a young, developing technology used to create images with extraordinary detail of body tissue or the brain by applying nuclear magnetic resonance phenomena. The MRI technique uses a pulse of radio-frequency energy to excite the hydrogen nuclei, the protons. The distribution of hydrogen nuclei of water and fat in the body depends on the tissue type and whether or not the tissue is healthy or diseased. The image brightness is a complex function of properties in the region of interest, which include parameters of protons density and the relaxation times of the protons. Manipulating these properties is accomplished by varying the experiment (pulse sequence) used at the time of examination to yield images that contains different contrast. Although MRI is normally a noninvasive technique, contrast agents can be administered to a subject to enhance a region of interest. There are now more than 22,000 MR systems in use worldwide. MR is one of the best diagnostic exams for imaging many types of soft-tissue including: the brain, the spine, the heart, aorta and coronary arteries, the organs of the upper abdomen and the pelvis as well as the joints.]
