title: Scirrhous metastases to the gastrointestinal tract at CT: the malignant target sign.
abstract: OBJECTIVE
  Our objective was to study the presence of a characteristic appearance of metastatic disease to the gastrointestinal tract on contrast-enhanced CT in patients with known malignancies and to investigate its clinical implications.
  
  
  CONCLUSIONS
  Twenty-five patients with scirrhous metastases had a malignant CT target sign. Careful observation and correlation with clinical history are required to differentiate this unique sign from a benign target sign.
