59-year-old woman with left breast mass. CC mammogram shows dense mass with sharply defined, lobulated contours, located at the inner part of the left breast.

Gray-scale sonogram. Smooth bordered semisolid mass with internally scattered, mostly circumferentially oriented anechoic multiple cyst, creating rosette appearance and accompanying echogenic material filled the intercystic spaces (hydatid sand).

Intercystic spaces were filled with homogenous echogenic material (hydatid sand) predominantly seen in the centre of the lesion, creating rosette appearance (wheel-spoke pattern) (Figure 2).
Axial contrast-enhanced thorax CT image. Hypodense, well-defined mass with capsular wall and internal septae, situated at the inner part of the left breast. The lesion shows capsular enhancement.

The breast lesion was heterogeneous hypodense with a smooth thick wall and septations, internally, had a density of 35 HU (Figure 3).
(a) Axial T1- and (b) T2-weighted MR images show that left breast mass with well-defined borders has multiple cystic loculations creating "rosette" pattern. Capsular wall and internal septae of the lesion are isointense on T1-weighted image and hypointense on T2-weighted image; marginally contrast enhancement seen on fat-saturated contrast enhanced T1-weighted image (c).

Short Tau Inversion Recovery (STIR) images. The capsular wall of the lesion enhanced marginally as smooth rim with a gradually increasing pattern, whereas internal septations and detached membrane were not enhanced at dynamic T1-weighted images (Figures 4(a), 4(b), and 4(c)). Superior and inferior polar outpouchings of the mass and capsular defect at the inferior edge were noteworthy.
STIR sequence image demonstrates hypointense capsule and detached internal membrane with perilesional fluid accumulation eccentrically, revealing focal rupture.

Mass was outlined with a curvilinear, minimal fluid collection near the defect, revealing a focal rupture (Figure 5).
The surgical specimen showed characteristic daughter cysts of hydatid disease.
