A 47-year-old woman with a history of subtotal gastrectomy due to gastric cancer underwent bone scintigraphy to evaluate possible recurrent disease. The whole-body images revealed a single focus of elevated 99mTc-MDP activity in the right pubic region, which was located in the intrapelvic soft tissue on subsequent SPECT/CT images. Pathological examination after needle biopsy demonstrated that the soft tissue was an implantation metastasis from gastric cancer.
Bone epithelioid angiosarcoma is an extremely rare osseous malignancy with an aggressive and destructive biological behavior. We present FDG PET/CT findings of a 59-year-old woman with left lower limb pain for 1 month. The images revealed abnormal activity in both left fibula and left tibia. In addition, abnormal activity in the sacrum and enlarged retroperitoneal lymph nodes was also noted. Pathological examination demonstrated bone epithelioid angiosarcoma.
