Teaching Points: 1. Gestational Trophoblastic Disease is an aberrant proliferation of placental trophoblastic tissue and encompasses a wide range of benign and malignant disease processes. 2. Imaging has played a crucial role in the early diagnosis of Gestational Trophoblastic Disease with ultrasound being the initial modality of choice. 3. MR and CT enable evaluation of myometrial invasion and extra-uterine extension of disease. 4. Characteristic radiographic signs can help differentiate the spectrum of Gestational Trophoblastic disease and its mimics. These signs will be illustrated in the exhibit.
