Figure 10a. Ossifying fibromyxoid tumor in a 32-year-old man. (a) Axial T2-weighted (4,500/160) MR image at the level of the stomach (S) shows a well-defined mass with multiple septa and an overall signal intensity higher than that of muscle, as well as a focal nodule of relatively low signal intensity (arrow). (b) Photograph of a resected specimen reveals myxoid components (white areas) separated by bands of fibrous tissue (arrowheads), as well as a soft-tissue nodule (arrow) that corresponds to the low-signal-intensity area seen on MR images. (c) Photomicrograph (original magnification, x100; hematoxylin-eosin stain) shows the trabecular or lacy arrangement of tumor cells in the myxoid matrix, with areas of marked ossification (arrow) that exhibited low signal intensity on MR images.
