Click Pelvic magnetic resonance images of a 34-year-old female patient with placental site trophoblastic tumor. Magnetic Resonance, T1 TSE, Philips Intera Pulsar 1.5T, TR=566; TE=10, Axial plane, no contrast.

Significant findings: hyperintense filling of the endometrial cavity related to the presence of blood.


Click Pelvic magnetic resonance images of a 34-year-old female patient with placental site trophoblastic tumor. Magnetic Resonance, T2 TSE, Philips Intera Pulsar 1.5T, TR=3500; TE=90, Axial oblique plane perpendicular to the long axis of endometrial cavity, no contrast.

Significant findings: Heterogeneous hyperintensity of the uterine corpus myometrium signal, with loss of the zonal anatomy.


Click Pelvic magnetic resonance images of a 34-year-old female patient with placental site trophoblastic tumor. Magnetic Resonance, three-dimensional fat-suppressed T1-weighted gradient-echo sequence (specifically, a T1-weighted high-resolution isotropic volume exception: THRIVE; Philips Medical Systems), Philips Intera Pulsar 1.5T, TR:5.6; TE:2.8, Sagittal plane, images acquired 120 seconds after the administration of 0.1mmol/kg of gadopentetate dimeglumine at a rate of 2mL/sec followed by a 20-mL saline flush at the rate of 2 mL/s.


Significant findings: Heterogeneous hyperintensity of the uterine corpus myometrium signal, with loss of the zonal anatomy.

Click Pelvic magnetic resonance images of a 34-year-old female patient with placental site trophoblastic tumor. Magnetic Resonance, diffusion-weighted MR image (b =0, 600, 1000sec/mm2), Philips Intera Pulsar 1.5T, TR=70.9; TE=2500, Axial plane, no contrast.

Significant findings: the tumor has high signal intensity (water restriction) with almost complete myometrial replacement.


Click Pelvic magnetic resonance images of a 34-year-old female patient with placental site trophoblastic tumor. Magnetic Resonance, apparent diffusion coefficient (ADC) map), Philips Intera Pulsar 1.5T, TR=70.9; TE=2500, Axial plane, no contrast.

Significant findings: The area of high signal intensity seen at diffusion-weighted MR imaging demonstrates low signal intensity, a finding that is consistent with impeded diffusion.
