The sonographic features of ten breast hamartomas are reported. Four masses
were clinically palpable. The mammographic appearance was characteristic of
hamartomas in five cases. In the remaining five lesions, because the
radiographic appearance was not pathognomonic, surgical excision was
required for pathologic confirmation of the diagnosis. A wide spectrum of
sonographic appearances was identified, the most frequent was that of a
moderate to well-circumscribed, solid, hypoechoic mass with posterior
acoustic shadowing. Two isoechoic hamartomas were very difficult to
visualize on sonography. We conclude that ultrasound has a minimal role in
the diagnosis of breast hamartomas, in view of their wide sonographic
variability.
