Resumo
Purpose: to evaluate, in a prospective way, the importance of
ultrasound features of solid breast lesions in the
differentiation between benign and malignant lumps.
Methods: one hundred and forty-two patients with solid
breast lesions, from the Department of Gynecology and
Obstetrics of the Federal University of Goias (Brazil), were
included in the trial. All ultrasound examinations were
performed by a training doctor, always supervised by an
experienced professional. The characteristics of the lesions
studied were: shape, retrotumoral echoes, internal echoes,
oriented diameter, halo of bright echoes and Cooper
ligaments. Each of the ultrasound features was compared to
the results of the histological examination.
Results: among the 142 patients included in the trial, 90
(63%) had their lesions excised, and 77 (86%) had
pathologic diagnoses of benign tumors and 13 (14%) of
malignant tumors. The following characteristics were
statistically significant in the diagnosis of the breast cancer
( χ 2 ): masses with retrotumoral shadowing (p=0.0001),
irregular shape (p=0.0007), heterogeneous internal echoes
(p=0.0015) and vertically oriented – taller than wide
(p<0.0001). The presence of halo of bright echoes anterior
to the lump and the presence of wider Cooper ligaments
were not related to the correct diagnosis of malignancy in
this trial.
Conclusion: ultrasound is a diagnostic method that can help
physicians between the differentiation of benign and
malignant breast lumps. The presence of retrotumoral
shadowing, irregular shape, heterogeneous internal echoes
and vertical orientation - lesions taller than wide - were
related to the pathologic diagnosis of breast malignancies.
