Radiographic images of the tumor. (a) An axial non-enhanced computed tomography image. A nodular lesion was seen adjacent to the uterus. The mass had low-density areas, and the peripheral and septal portions were isodense relative to the uterus. (b–d) Magnetic resonance images in the axial plane. The tumor had an intermediate to low signal intensity on a T1-weighted image; (b) a high signal intensity, particularly of the cavities, on a T2-weighted image (c); and a multilocular enhancement pattern on a contrast-enhanced, fat-suppressed T1-weighted image (d). The white bars represent 5 cm
