title: [Discovery of benign hepatic lesions during investigation for hepatic metastases].
abstract: Benign lesions may be unexpectedly discovered when investigating for liver metastases. This is illustrated here by 6 cases of alleged liver metastasis in patients previously operated upon for cancer and referred for hepatectomy. The diagnosis was corrected by additional examinations or on surgery. A model of diagnostic and therapeutic approach is suggested. As a rule, a cystic lesion seen on ultrasonography does not require supplementary arteriography and needle biopsy -- are necessary in cases of dense, heterogeneous lesions.
