Fluorodeoxyglucose positron emission tomography/computed tomography and magnetic resonance imaging of uterine leiomyosarcomas: 2 cases report / 中华医学杂志(英文版)

Uterine leiomyosarcoma is an uncommon malignant neoplasm of smooth muscle origination and is associated with a poor prognosis. We report two cases of uterine leiomyosarcoma that presented with pulmonary metastases. 2-deoxy-2-(¹⁸F)fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) was performed to identify the primary carcinoma and found the focus located in the uterus. The follow-up magnetic resonance imaging (MRI) confirmed the diagnosis was uterine leiomyosarcoma.
