FIGURE 1. Unexpected extraabdominal disease in 64-y-old woman with known perirectal recurrent adenocarcinoma. DHC 18F-FDG study was assessed for staging before surgery. In addition to recurrent tumor (long arrow), sites of increased uptake were also detected in left breast (short arrow) and left axilla (arrowhead), suggesting second metastatic primary cancer. Left hydronephrosis and hydroureter were also detected. Removal of perirectal tumor and mastectomy with axillary dissection were performed during surgery.
