Clustered microcysts

Clustered microcysts, or a microcystic cluster, refer to part of the spectrum of cystic change in the breast on ultrasound. They are part of aberrations in development and involution of the breast.

These lesions have no malignant potential 1,2.

These lesions are not symptomatic or palpable 3.

These appear as a cluster of anechoic foci, each less than 2-3 mm in diameter, with thin (less than 0.5 mm) intervening septations and no discrete solid components.

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.
