Figure 9b. Leiomyomas with coagulative necrosis in a 38-year-old woman. (a, b) Axial T2-weighted fast SE MR image (a) and T1-weighted SE MR image (b) show two intramural leiomyomas (straight arrows), which have lower signal intensity than the myometrium on the T2-weighted image (a) and higher signal intensity on the T1-weighted image (b). A small amount of liquefactive degeneration is present in the lateral aspect of the left-sided tumor (curved arrow). (c) Photomicrograph (original magnification, x40; hematoxylin-eosin stain) of the larger myoma shows a homogeneous matrix without recognizable cells, findings that correspond to coagulative necrosis.
