Sonographic features of breast hamartomas.

Abstract

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.

Benign breast lesions: Ultrasound

“…US image (Fig. 8) is usually heterogeneous with a variable mixture of isoechoic elements (fat and glandular tissue) and hyperechoic elements (fibrous connective tissue); it sometimes shows a target or multilayered appearance which is pathognomonic like the mammographic features [52,53]. Consistency and compressibility depend on the fat component, which is extremely variable.…”

Hamartomas from head to toe: an imaging overview

“…The sonographic appearance of this lesion has wide variability owing to varying amounts of fatty, fibrous and glandular tissues. 39 The most common ultrasound appearance is that of a circumscribed and compressible oval mass, composed predominantly of a hyperechoic fatty component. Heterogeneous echogenicity is frequently present.…”

Breast Hamartoma: a Case Report

“…It is actually a result of the hamartoma pushing normal parenchyma aside rather than replacing it. Breast hamartoma has a wide variation of sonographic appearance, which is not helpul for differential diagnosis (9). It is pointed out that in mammographically and clinically detected hamartomas, most have heterogeneous echogenecity without posterior acoustic shadowing (3).…”
