18F-NaF Uptake in Retroperitoneal Neurofibroma and Uterine Leiomyoma Calcifications.

Abstract

A 48-year-old woman with intermittent lower back pain for 9 months and known retroperitoneal neurofibroma underwent F-NaF PET/CT scan to assess possible bony lesions causing the pain. Incidentally, the images showed elevated NaF activity in the retroperitoneal neurofibroma. In addition, uterine leiomyoma with heterogeneous calcifications revealed increased NaF activity.
