Code | Display | Definition |
Cyst | Cyst | A cyst is a sac-like pocket of membranous tissue
that contains fluid, air, or other
substances.
Cysts can grow almost anywhere in the body or under
the skin.
Valid for the following modalities: MG US MRI. |
CystComplex | Cyst complex | Complex cysts have irregular or scalloped borders,
thick walls, and some evidence
of solid areas and/or debris in the fluid.
These solid areas echo back the sound waves from
the ultrasound.
A complex cyst is sometimes aspirated, or drained
with a fine needle, so that the
fluid inside can be tested.
If blood or any unusual cells are present, further
testing may be needed to rule
out breast cancer.

Valid for the following modalities: MG US. |
CystComplicated | Cyst complicated | Complicated cysts are "in between" simple and complex.
Although they share most of the features of simple
cysts, they tend to have some
debris inside them and echo back some of the ultrasound
waves.
However, they don't have the thick walls or obvious
solid components that a complex
cyst has.

Valid for the following modalities: MG US. |
CystMicro | Cyst micro | A microcyst Is a sac-like pocket of tissue that contains
fluid, air, or other substances.
A Microcyst is small and less than 2-3 mm and are
often in clusters and only show up on a mammogram
or ultrasound.
Valid for the following modalities: US. |
CystOil | Cyst oil | Oil cysts are filled with fluid that may feel smooth
and soft/squishy.
Oil cysts are caused by the breakdown of fatty tissue.
Valid for the following modalities: MG US. |
CystSimple | Cyst simple | A simple cyst is a sac-like pocket of membranous
tissue that only contains clear
fluid.
Valid for the following modalities: MG US. |
CystWithDebris | Cyst with debris | A cyst that is filled with debris and fluid substance.
It Is either considered a complex or complicated
cyst.
The type of debris determines what kind of cyst.
