Figure 3. FDG-PET/CT scan A: There is an FDG avid (SUVmax = 17.0) soft
tissue mass in the pre-coccygeal region (arrows) measuring 3.8 x 3.0 cm.
B: There is an FDG avid (SUVmax = 6.3) soft tissue lesion in anterior
pelvic wall (blue arrow) measuring 1.3 x 1.2 cm reveals metastatic
lesion.
She underwent CT guided biopsy from the per-sacral mass, and it revealed
poorly differentiated carcinoma.
Due to the multiple recurrent lesions and the presence of metastasis,
she was referred for chemotherapy. There was no treatment response
despite the numerous chemotherapy courses, and the disease progressed.
Her pelvic pain was difficult to control by the nerve block and
palliative measures. Finally, one year after the diagnosis, she,
unfortunately, passed away due to the progression of metastatic
abdominopelvic lesions.
