A microcystic cluster refers to part of the spectrum of cystic change in the breast on ultrasound.
These small lesions are found on high resolution ultrasound imaging of the breast; before the days of high resolution ultrasound these lesions were unknown.
They consist of groupings of minute cysts that are grouped together and form part of the spectrum of benign cystic change in the normal breast. This is part of normal breast parenchyma and these lesions are not symptomatic. They are part of normal development and involution of the breast (ANDI).
Clusters of minute cysts that group together. These lesions have no malignant potential 1
There is no solid component to these lesions and they are not symptomatic or palpable 2
These lesions rarely cause confusion and are encountered daily in ultrasound practice. These lesions do not change significantly with time except for normal involution associated with senescent changes in the breast. Note them and move on.
