ABSTRACT: Here we report imaging studies of a patient with pulmonary benign metastasizing leiomyoma (BML). A 44-year-old woman who underwent a hysterectomy for uterine cellular leiomyoma presented with abnormal shadows on a chest X-ray. Chest computed tomography (CT) revealed multiple well-defined nodules in both lungs. Chest magnetic resonance imaging (MRI) indicated these nodules as T1-low/T2-high intensity lesions. Contrast-enhanced MRI indicated these nodules as well-enhanced lesions, while 18F-fluorodeoxyglucose positron emission tomography-CT revealed no abnormal accumulation in these nodules. Bilateral lung wedge resections were performed for the largest 2 lesions to confirm the diagnosis, and both nodules were histologically diagnosed as BML.
