Diffusion-weighted imaging of a malignant brenner tumor.
Microscopically, ovarian malignant Brenner tumor shows components of malignant transitional cell tumor intermixed with benign and borderline elements. We report a case of this tumor with components that transition from benign to malignant on diffusion-weighted images (DWI) and in histologic findings. The benign component showed low signal intensity on T(2)-weighted images, whereas the malignant...
متن کاملMalignant brenner tumor of ovary.
Brenner tumor is a relatively uncommon neoplasm. It constitutes 1.4–2.5 % of all ovarian tumors and has a predilection for the postmenopausal women. Most Brenner tumors are benign, with only 2–5 % being malignant. The malignant components of the tumor, which show heterogeneous epithelial growth and atypia with intervening stroma, consist of transitional cells, squamous or undifferentiated carci...
متن کاملDiffusion-Weighted MR Imaging in Brain Tumor
Primary neoplasms of the central nervous system (CNS) have a prevalence of between 15,000 and 17,000 new cases annually in the United States and are estimated to cause the deaths of 13,000 patients. Gliomas are the leading cause of primary CNS tumors, accounting for 40–50% of cases and 2–3% of all cancers4. Despite new treatment techniques, patients’ survival still remains very low, varying bet...
متن کاملDifferential chemosensitivity of tumor components in a malignant oligodendroglioma: assessment with diffusion-weighted, perfusion-weighted, and serial volumetric MR imaging.
We report the case of malignant oligodendroglioma in a 36-year-old man who underwent diffusion-weighted, perfusion-weighted, and volumetric MR imaging before and after PCV (procarbazine, CCNU, vincristine) chemotherapy. The tumor regions exhibiting a low apparent diffusion coefficient and increased relative cerebral blood volume showed a marked response to chemotherapy and dramatic decrease in ...
