The 18F-FDG PET/CT of patient before operation. (A) The image revealed hypermetabolic lesions in the right thorax (long arrow) and the right upper abdomen (short arrow). (B-D) On the axial CT, PET, and fused PET/CT showed a large irregular lesion in the right lung upper lobe, measuring 8.4 cmx10.2 cmx8.1 cm showing intense 18F-FDG uptake with SUVmax of 13.4. (E-G) The axial CT, PET, and fused PET/CT revealed the increased activity corresponded to a slight hypodense right adrenal gland soft tissue mass, measuring 5.1 cmx6.3 cmx6.5 cm showing intense 18F-FDG uptake with SUVmax of 13.4.

The maximum intensity projection image ( Figure 1A ) revealed hypermetabolic lesions in the right thorax ((long arrow) and the right upper abdomen (short arrow). On the axial CT ( Figure 1B ), PET ( Figure 1C ), and fused PET/CT ( Figure 1D ) showed a large irregular lesion in the right lung upper lobe, measuring 8.4 cmx10.2 cmx8.1 cm showing intense 18F-FDG uptake with SUVmax of 13.4. The axial CT ( Figure 1E ), PET ( Figure 1F ), and fused PET/CT ( Figure 1G ) revealed the increased activity corresponded to a slight hypodense right adrenal gland soft tissue mass, measuring 5.1 cmx6.3 cmx6.5 cm showing intense 18F-FDG uptake with SUVmax of 13.4.
High-grade Endometrial Stromal Sarcoma in the right adrenal gland. (A, B) The tumor cells were seen in a swirling flow structure. (C) CD10 (+).

On histopathological examination, the tumor cells were seen arranged in a swirling flow structure ( Figures 2A, B ). Immunohistochemistry showed: ER (-), PR (-), CD10 (+) ( Figure 2C ), P16 (+), Ki-67 (50%).
