Gestational Trophoblastic Disease: A Multimodality Imaging Approach with Impact on Diagnosis and Management
A 25-year-old patient presenting with episodic torrential vaginal bleeding, 3 months after completion of chemotherapy for choriocarcinoma. β-hCG levels were not raised. Grey-scale TAS (a) shows two large anechoic lesions in the myometrium (arrows). Color Doppler (b) demonstrates a whirled to-and-fro color flow in these cystic spaces. CT angiogram image (c) reveals a grossly dilated left uterine artery (arrowheads) with a saccular pseudoaneurysm (thick arrow) showing a narrow neck (thin arrows) arising from it and protruding into the adjoining myometrium.
