The breast within a breast sign refers to the common mammographic appearance of breast hamartomas (fibroadenolipomas). Since these benign lesions are well-circumscribed and contain a mixture of fibrous, glandular and fatty tissue (just like normal breast), it is not surprising that they appear v...
Egg shell calcifications in the breast are benign peripheral rim like calcifications
They represent calcifications secondary to fat necrosis, calcification of oil cysts.
thin rim like calcification (< 1mm in thickness)
small to several cent...
Linguine sign is one of the imaging signs of intracapsular rupture of a breast implant.
After implantation of a silicone or saline breast implant, a fibrous capsule (scar) forms around the implant shell. In an intracapsular rupture, the contents of the implant are contained by the fibrous scar,...
Popcorn calcification refers to amorphous calcifications often with rings and arcs that resemble popped corn kernels. This type of calcification may be seen in many radiological settings including 1:
chondroid lesions (e.g enchondroma, chondrosarcoma)
Popcorn calcification in the breast is the classical description for the calcification seen in involuting fibroadenomas, which as the name suggests has a pop corn like appearance.
A fibroadenoma in the long run may degenerate and calcify. Initially there are a few punctate periphera...
Punctate microcalcifications in the breast are defined as calcific opacities < 0.5 mm in diameter seen within the acini of a terminal duct lobular unit.
rarely in DCIS (punctate, clustered, segmentally distributed)
Salad oil sign, also referred as droplet sign, is characterised by small rounded high T2 signal foci within a breast implant on MRI studies and represents water droplets or small amounts of air within the silicone. It also can be characterised as hypointense foci on the water-suppressed sequence...
Snowstorm sign may refer to:
snowstorm sign - complete hydatiform mole (ultrasound)
snowstorm sign - extracapsular breast implant rupture (ultrasound)
Snowstorm sign on breast ultrasound imaging represents the presence of free silicone droplets mixed with breast tissue giving a characteristic heterogeneous echogenic appearance with the dispersion of the ultrasound beam. It is considered the most reliable sign of extracapsular breast implant ru...
Stepladder sign may refer to:
intra-capsular breast implant rupture (ultrasound)
air-fluid levels in obstructed small bowel (erect abdominal radiograph)
Stepladder sign is a sonographic sign indicating an intracapsular breast implant rupture. It is considered the most reliable ultrasonographic finding in silicone gel breast implant intracapsular rupture. It is identified as multiple, discontinuous, parallel, linear echoes in the lumen, and is an...
The tattoo sign is a feature given to describe dermal calcifications seen on mammography 1. The basis of this sign is that dermal calcifications maintain fixed relationships to one another which are reproducible with similar projections at different times. This is in contrast to intramammary cal...
The tent sign is a term referred to a characteristic of the posterior edge of the breast parenchyma when a mass (usually an infiltrating lesion) causes its retraction and forms a "V" that resembles the tip of a circus tent.
The detection of a "tent-sign" is facilitated by t...
