Solid mature teratoma of the ovary: appearances at MR imaging.
Magnetic resonance imaging (MRI) appearances of a case with rare solid mature teratoma of the ovary is presented. The lesion was almost entirely solid with small cystic component. The solid tissue, consisting of bronchial cartilage, smooth muscle, glands, and epithelium, exhibited hypointense signal on T1-weighted image, relatively hyperintense signal on T2-weighted image, and reticular pattern of enhancement on the postcontrast scan. The presence of fatty tissue mixed with hair bundle, which did not exhibit a signal intensity of fatty tissue, was clearly indicated by chemical shift artifact within the cystic component.
