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.

Which is the best description of a circumscribed mass?
Often masses that are circumscribed may be overlapped by parenchyma in some areas. These are described as obscured or partially circumscribed. A microlobulated margin appears as fine nodularity or undulation of the edge of the lesion and implies a more malignant nature.
Can a circumscribed mass be cancer?
Circumscribed oval and round masses are usually benign. An irregular shape suggests a greater likelihood of malignancy. The margins can be described as circumscribed, microlobulated, obscured (partially hidden by adjacent tissue), indistinct (ill-defined), or spiculated (characterized by lines radiating from the mass).
What is a focal density in a mammogram?
By definition, a focal asymmetric density is seen on two mammographic views but cannot be accurately identified as a true mass (,,,Fig 4). Although a focal asymmetric density may represent normal breast tissue, further evaluation is often warranted to exclude a true mass or architectural distortion.
What is a well circumscribed lung nodule?
A solitary pulmonary nodule is a well-circumscribed round lesion measuring up to 3 cm in diameter and surrounded by aerated lung. Once a nodule is discovered, clinical and radiologic features and quantitative models can be used to determine the likelihood of malignancy.
What does a Nodular density on a mammogram mean?
The finding of a nodular density on mammogram refers to fibrocystic changes that are usually benign. However, the presence of nodular densities makes the mammogram more difficult to read because it is more difficult to see a small lesion on mammogram or to palpate a definite lump on physical exam.

In Table 4.1 the differential diagnosis of circumscribed masses based on their density is shown. Masses that are fatty—lipomas, oil cysts, and galactoceles—and circumscribed masses that are mixed density are characteristically benign.
How are nodules and masses divided into tumorlike conditions?
Magnetic resonance imaging (MRI) and positron-emission tomography are complementary techniques that can provide additional staging and prognostic information [1]. Pleural nodules and masses can be divided into tumoral lesions and tumorlike conditions.

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.
By definition, a focal asymmetric density is seen on two mammographic views but cannot be accurately identified as a true mass (,,,Fig 4). Although a focal asymmetric density may represent normal breast tissue, further evaluation is often warranted to exclude a true mass or architectural distortion.
How big is a nodule on a CT scan?
Lung nodules — small masses of tissue in the lung — are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size.
How big is a lung nodule in centimeters?
Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A larger lung nodule, such as one that’s 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule.
