forming acute angles. 
The margin of the mass is not circumscribed. 


Valid for the following modalities: US.</td></tr><tr><td style="white-space:nowrap">CircumscribedMargin<a name="MarginCS-CircumscribedMargin"> </a></td><td>Circumscribed margin</td><td>A circumscribed margin is one that is well defined, 
with an abrupt transition between 
the lesion and the surrounding tissue. 
For US, to describe a mass as circumscribed, its 
entire margin must be sharply defined. 
Most circumscribed lesions have round or oval shapes.

Valid for the following modalities: MG US MRI.</td></tr><tr><td style="white-space:nowrap">IndistinctMargin<a name="MarginCS-IndistinctMargin"> </a></td><td>Indistinct margin</td><td>There is no clear demarcation of the entire margin, 
or of any portion of the margin, 
from the surrounding 
tissue. 
For mammography, this descriptor should not be used 
when the interpreting 
physician believes it is likely due to immediately 
adjacent breast tissue. 
Use of this descriptor 
usually implies a suspicious finding.

of primary breast carcinoma, 
and is an important consideration in patients undergoing 
breast conservative surgery.

Valid for the following modalities: US.</td></tr><tr><td style="white-space:nowrap">IrregularMargin<a name="MarginCS-IrregularMargin"> </a></td><td>Irregular margin</td><td>Edges around the soft tissue that don't look smooth. 
Indicative of some sort of growth or mass rather 
than a cyst.

Much like a 6 or 8 leaf clover. 
The edge of all of the leaves would be considered 
lobulated. 


Valid for the following modalities: US.</td></tr><tr><td style="white-space:nowrap">MacrolobulatedMargin<a name="MarginCS-MacrolobulatedMargin"> </a></td><td>Macrolobulated margin</td><td>Smooth margin with distinct separation between the 
mass and the surrounding border. 
Macrolobulaed margins are  oval-shaped and  have 
a wide rather than tall formation. 


Valid for the following modalities: MG.</td></tr><tr><td style="white-space:nowrap">MicrolobulatedMargin<a name="MarginCS-MicrolobulatedMargin"> </a></td><td>Microlobulated margin</td><td>The margin is characterized by short-cycle undulations 
or scalloped appearance,and 
the margin of the mass is not circumscribed.

Valid for the following modalities: MG US.</td></tr><tr><td style="white-space:nowrap">NonCircumscribedMargin<a name="MarginCS-NonCircumscribedMargin"> </a></td><td>Non circumscribed margin</td><td>The mass has one or more of the following features: 
indistinct, 
angular, microlobulated, or spiculated in any portion 
of the margin There is not a clear demarcation between 
the mass and the surrounding 
tissue.

tissue. 
This is used primarily when some of the margin of 
the mass is circumscribed, but 
the rest (more than 25%) is hidden.

from the mass, often a sign 
of malignancy, 
but the significant feature is that the margin of 
the mass is not circumscribed.
