A nodular lesion in the pelvis (arrow). A, B A contrast-enhanced MRI (T1-weighted with fat suppression) showed an intrapelvic lesion increasing in size from 13 to 19 mm after 4 months. C, D A contrast-enhanced CT showed a 20-mm nodular lesion with a contrast effect. E FDG-PET/CT showed a low accumulation of FDG in the nodular lesion. F SRS showed the low expression of somatostatin receptors in the nodular lesion.
