Diagnosis: Benign Metastasizing Leiomyoma
Radiologic Findings: On initial chest radiograph, multiple small nodular opacities were noted in both lung fields.Initial chest CT showed multiple small nodules in the bilateral lungs, and there was no evidence of calcification within the nodules.
Follow-up chest CT taken 13months later showed slightly increase in size of some of these nodules in the bilateral lungs. There was no evidence of mediastinal lymph node enlargement.
One month after the follow-up CT, the FDG PET was performed and showed no definite FDG uptakes of these nodules.

PHx> s/p TAH due to submucosal leiomyoma 11 months ago

Lung, percutaneous needle biopsy results: Consistent with leiomyoma (CD34: Negative, Desmin: Positive, Smooth muscle actin: Positive, S-100: Negative)
