[Percutaneous injection of a contrast medium in isolated lesions of the breast]

The percutaneous injection of contrast medium was performed into 44 breast fibroadenomas, 13 tumors of fibrocystic disease and 5 cancers. The radiological aspect does not to assure some discrimination between peri- or intracanalicular fibroadenomas, nor between giant fibroadenomas and cystosarcoma phyllodes. The opacification of the intratumoral galactophoric channels is achieved in 34,1% of fibroadenomas. It can be observed in fibrocystic disease but nor in cancer. A pattern of fibrous tissue and/or opacification of large peripheric extratumoral channels will appear in 34,1% of fibroadenomas. They are be observed in fibrocystic diseases and cancers. It is the same thing for spot figure. For diagnosis, the technic is not recommended to be generalized since the accuracy seems to be less serious than the cytological analysis of the puncture.
