PET/CT of Delayed Uterine Leiomyoma Metastasizing to Lung and Femur

Abstract

Benign metastasizing leiomyomas are benign disseminated extrauterine tumors in patients with prior history of uterine leiomyomas and may occur years after hysterectomy. The lung is mostly affected, with a less common occurrence in the brain, heart, spine, retroperitoneum, and bone. We present the role of ¹⁸F-FDG PET/CT in the metabolic staging and postsurgical monitoring of a patient with lung and femoral involvement.
