case_images: Magnetic resonance (MR) images of an intrapelvic IVL tumor in a 50-year-old woman. A mixed solid and cystic pelvic mass extended from the intermuscularis to the subserosa, as well as the extrauterine environment and had a worm-like appearance. The lesions showed isointensity on T1WI (A) and inhomogeneous signal intensity on T2WI (B) (arrow). The diffusion-weighted image (b-value = 800 s/mm2) (C) indicates high signal intensity in most of the mass (arrow). Apparent diffusion coefficient (ADC) mapping (D) shows high intensity within the mass (arrow). Strong homogeneous enhancement is seen in the arterial (E) and delayed (F) phases on the T1 sagittal image. All images were obtained using a 1.5-T MR scanner (Achieva, Philips Medical Systems).

case_images: T1W1 signal was observed after gadolinium chelate injection (Figure 1). The endometrium was pressured, and the lymph nodes were normal.
case_images: (A) Images from the operating theater. (B) Histology of the resected tumor at x10 magnification. Intravascular tumor presents within the lumen of a vein, showing dense proliferation of uniform spindle-shaped smooth muscle cells. (C) The smooth muscle compartment is shown by h-caldesmon staining (h-caldesmon, 100x).
