Breast within a breast sign

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...

Eggshell calcification (breast)

Eggshell calcifications in the breast are benign peripheral rim like calcifications Pathology They are typically secondary to fat necrosis or calcification of oil cysts. Radiographic features thin rim-like calcification (<1 mm in thickness) lucent centers small to several centimeters in di...

Keyhole sign (intracapsular breast implant rupture)

The keyhole or noose sign indicates an uncollapsed intracapsular breast implant rupture seen as the focal invagination of the implant shell caused by a small concealed leak of silicone outside shell where the two membranes do not contact each other. It is best appreciated by MRI. Differential d...

Linguine sign (breast)

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

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) fibrous dysplasia pulmonary hamartomas ...

Popcorn calcification within the breast

Popcorn calcification in the breast is the classical description for the calcification seen in involuting fibroadenomas which, as the name suggests, has a popcorn-like appearance.  Pathology A fibroadenoma in the long run may degenerate and calcify. Initially there are a few punctate periphera...

Punctate microcalcification within the breast

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. Pathology Associations fibrocystic changes skin calcification skin talc rarely in DCIS: punctate, clustered, segmentally distributed Radi...

Salad oil sign

Salad oil sign, also referred to as the droplet sign, is characterized by small rounded high T2 signal foci within a breast implant on MRI studies and represents water droplets or small amounts of gas within the silicone. It also can be characterized as hypointense foci on the water-suppressed s...

Snowstorm sign (disambiguation)

Snowstorm sign may refer to: snowstorm sign: complete hydatiform mole (ultrasound) snowstorm sign: extracapsular breast implant rupture (ultrasound) snowstorm sign: thyroid pulmonary metastases (chest radiograph)

Snowstorm sign (extracapsular breast implant rupture)

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 (disambiguation)

Stepladder sign may refer to: intracapsular breast implant rupture (ultrasound) gas-fluid levels in obstructed small bowel (erect abdominal radiograph)

Stepladder sign (intracapsular breast implant rupture)

The 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 i...

Subcapsular line sign (intracapsular breast implant rupture)

The subcapsular line sign is a small localized leak from a silicone implant that leads to the formation of a thin layer of silicone between the implant shell and the fibrous capsule. It represents a minimally collapsed intracapsular breast implant rupture. It is best appreciated by MRI.

Tattoo sign (mammogram)

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 that are reproducible with similar projections at different times. This is in contrast to intramammary calc...

Teardrop sign (intracapsular breast implant rupture)

The teardrop sign indicates an uncollapsed intracapsular breast implant rupture and is seen as a small focal invagination of the implant shell caused by a minimal concealed leak of droplets of silicone outside the shell where the two membranes contact each other. It is best appreciated by MRI. ...

Tent sign (breast)

The tent sign is a term referring to a characteristic appearance of the posterior edge of the breast parenchyma when a mass (usually an infiltrating lesion) causes its retraction and forms an inverted "V" that resembles the tip of a circus tent. The detection of a "tent sign" is facilitated by ...
