What does circumscribed mass mean?

Circumscribed masses. A circumscribed mass in mammography is a mass where the contour is clearly defined along at least 75% of its surface. The remaining 25% may, at most, be masked by the adjacent gland. Circumscribed masses first indicate benign lesions.

Is there a Nodular density in the left breast?

Recent sceening mammogram stated a nodular density is identified posteriorly in left breast. Went back for spot compression of left breast and received the following report from the radiologist: Upon spot compression, the area in question becomes less defined.

What is the differential diagnosis for posterior mediastinal mass?

The differential diagnosis for a posterior mediastinal mass includes: neoplasm neurogenic tumors – most common nerve sheath tumors schwannoma. neurofibroma.

Where are the masses on the left breast?

At the 8 o’clock position of the left breast there is a well-defined oval mass of heterogeneous (predominantly hyperechoic) echogenicity. Pathology • Fibrocystic change

What’s the difference between low density and high density?

‘ Density ‘ is usually classified as either fatty, low, iso-dense or high. The mass is probably benign for fatty and low densities, moderately suspicious of malignancy for an iso-density and highly suspicious of malignancy at high densities. The mammographic characteristics of breast masses is quite a complex and detailed study.

Which is more likely high density or low density breast cancer?

A mass with a density higher than of the surrounding fibroglandular parenchyma is more likely to be malignant than a low-density mass (Fig. 5.2a–c ). In a retrospective study of 348 breast masses with biopsy confirmation, 70.2 % of the high-density masses were malignant, and 22.3 % of the iso- or low-density masses were malignant [ 6 ].
