Skeletal muscle metastasis of
gastric cancer is extremely rare and is associated with various symptoms. Here, we
report on a 60-year-old
woman with right
hip pain after excessive
walking. Two years earlier, the
patient had been treated for advanced
gastric cancer (
surgery,
adjuvant chemotherapy). Upon
magnetic resonance imaging, diffuse
muscle swelling and high signal intensity were observed in T2-weighted images of the right
hip muscle. However, the FDG uptake in the right gluteal
muscles was not obviously increased. Pathological examination of
muscle biopsy revealed metastatic
adenocarcinoma of
stomach origin. The
patient was treated with
chemotherapy, and the swelling and
pain in the right
hip are progressively improving.
