This case is a very good example of how a multimodality approach was taken in diagnosis and management of patient with suspected uterine sarcoma, which turned out to be uterine leiomyoma with parasitic leiomyoma mimicking the pararenal deposit. There has been an increased use of fluorodeoxyglucose avid positron emission tomography-computed tomography in pelvic malignancies, especially in the cases where there is suspected extrapelvic spread. It was an interesting finding of parasitic leiomyoma, which can be easily thought to be as deposit/mass in a patient with pelvic malignancy.
