[Color Doppler ultrasonography in the diagnosis of solid breast lesions].

The color-Doppler signals in 50 patients with breast lumps were assessed subjectively. Number and location of vessels within the masses were recorded and compared with histologic diagnosis and lesion size. All the malignancies were vascularized but only 16/37 of the benign ones showed vessels. All malignancies but one displayed > or = 2 vessels, which on the other hand occurred in only 4/16 vascularized benignancies. There was a relation between size of the lesion and number of the observed vessels, and color-Doppler proved more reliable in the differential diagnosis of breast masses when lesions less than 2 cm were considered.
