Diagnostic challenge of lipomatous uterine tumors in three patients

Figure 1 Computed tomography, ultrasound and magnetic resonance images of lipomatous uterine tumor in a 79-year-old woman. A and B: Computed tomography axial images of the pelvis without contrast (A) and with intravenous contrast (B) show a non-enhancing lesion in left side of the uterine fundus (long arrows); C: The density is similar to that of subcutaneous fat. Ultrasound of pelvis in transverse view shows a hyperechoic lesion (2.46 cm × 2.11 cm) in the uterine fundus; D: T1-weighted axial MRI image shows a homogeneous hyperintense lesion in left side of uterine fundus; E: The lesion shows complete suppression of signal intensity in T1-weighted fat-suppressed sequence, suggestive of fat component; F: No contrast enhancement is seen after intravenous gadolinium is administered. Compression of the uterine cavity is clearly demonstrated. Magnetic resonance imaging (MRI) images of the lesion (short arrows) (D-F).
