Presurgical Identification of Uterine Smooth Muscle Malignancies through the Characteristic FDG Uptake Pattern on PET Scans

Figure 3

Illustrative images of two patients with leiomyosarcomas (LMS) (the case numbers reported in Figure 3 correspond to those in Table 2). Case #1 had a high-grade LMS and showed the “hollow ball” sign on the coronal view of the FDG PET image (a), PET/CT fusion image (b), and maximum-intensity projection image (c). Case #6 had a low-grade LMS and showed the “hollow ball” sign on the coronal view of the FDG PET image (d), PET/CT fusion image (e), and maximum-intensity projection image (f).
