We present a 61-year-old woman who suffered from peritoneal cancer surgery 2 years ago, referred for 99mTc-MDP bone scan because of higher serum CA-125 level, which showed multiple intense tracer activities in her abdominal and pelvic region without other abnormalities. SPECT/CT revealed the activities were loaded in the intestine but not in the bone. A wait-and-see policy was adopted because of no abdominal discomfort. After 1-year follow-up, another bone scintigraphy showed the tracer uptake was significantly decreased.
