Ultrasound nonmass breast lesion features may signal malignancy

By Amerigo Allegretto

Some nonmass breast lesion characteristics on ultrasound exams can be considered suspicious for malignancy at screening ultrasound.

November 5, 2024

Images depict a 43-year-old woman with a malignant nonmass lesion that was diagnosed as microinvasive ductal carcinoma. (A) Transverse and (B) longitudinal ultrasound images show a hypoechoic nonmass lesion (solid arrows) with segmental distribution in the left breast. The lesion has associated calcifications (dashed arrows in A). (C) Longitudinal color Doppler ultrasound image shows high vascularity. (D) Magnified image in the mediolateral oblique view from screening mammography shows grouped calcifications (arrows), which are considered a mammographic correlate of the ultrasound-detected nonmass lesion (A radiopaque marker attached to the skin is visible in the image because the mammographic exam was performed after screening breast ultrasound). Ultrasound-guided core needle biopsy and pathologic examination revealed ductal carcinoma in situ, but the lesion was upgraded to microinvasive ductal carcinoma at subsequent surgery (2.5-cm ductal carcinoma in situ, histologic grade II, estrogen receptor-positive, progesterone receptor-positive, human epidermal growth factor receptor type 2-negative).

Could elastography replace conventional ultrasound-guided FNAC?

By Amerigo Allegretto

Strain elastography does not have additional benefits over conventional elastography-guided FNAC for diagnosing malignancy in thyroid nodules.

October 15, 2024

Images depict a 43-year-old woman with a solitary left-sided thyroid nodule classified at gray-scale ultrasound as category U3, upgraded to category U4 at strain elastography, and classified as category Thy4 at cytopathologic examination. Subsequent surgical histopathologic examination confirmed papillary cell carcinoma. (A) Longitudinal view of the left thyroid lobe demonstrates the low reflective nodule (between arrows) measuring 13 × 12 × 11 mm (not shown) and with a halo. (B) A longitudinal image with side-by-side visualization of the nodule (arrow) at gray scale (left) and strain elastography (right). The nodule is predominantly blue, indicating increased stiffness. (C) A longitudinal view shows the needle (arrows) within the stiffer aspect of the nodule for cytology sampling. U and Thy categories are according to British Thyroid Association system.
