Are all Spiculated masses malignant?
Mammographically, such lesions are often similar, and only some can be differentiated on the basis of morphologic characteristics. Although microcalcifications are often associated with breast carcinoma, not all spiculated lesions with microcalcifications are malignant.
What is the meaning of Spiculated masses?
(SPIH-kyoo-LAY-ted …) A lump of tissue with spikes or points on the surface.
What does spiculated margins mean?
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 stellate opacity?
It presents a large opacity with ill-defined borders, which is not characteristic. It can appear as an architectural distortion. In contrast, the typical stellate image is less common because it has no elastosis. The dense center is often as dense or less dense than that of the parenchyma.
What is a Spiculation?
Spiculation is a stellate distortion caused by the intrusion of breast cancer into surrounding tissue. Its existence is an important clue to characterizing malignant tumors. Many successful mammographic methods have been proposed to detect tumors with spiculation.
Can a spiculated mass be benign?
Although a spiculated mass is thought of as a classic finding of malignancy on mammography, ultrasound, and MRI, its differential diagnosis includes benign lesions.
Can spiculated margins be benign?
What does Spiculation mean?
1 : covered with or having spicules : spicular, prickly. 2 : divided into small spikelets.
Is a 1.6 cm lung nodule big?
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.
