Schwannoma of the right psoas major. (a) CT- coronal plane. (b) PET- coronal plane. (c) PET/CT fusion image. As indicated by the red arrow, the density of the mass was slightly lower than that of the adjacent muscle tissue. Moreover, the uptake of 18F-FDG increased moderately and homogeneously. Tumor size = 2.5 cm, SUVmax = 3, HF = 0.36, TLG = 25.5, MTV = 15 cm3, and P value = 0.21
