case_images: On US imaging, diffuse hypoechoic collections are observed in the glandular tissue in both breasts (a), and thick septations(b) are noticeable. These collection areas (blue asterisk) extend into the pectoral muscle fibers (red arrow) up to the axillary tail (c). Cell block with hematoxylin and eosin stain (d) and fine needle aspiration smears with May-Grunwald-Giemsa stain (e-f) showed abundant amorph gelatinous material.

case_images: Initially, ultrasound revealed heterogeneously and asymmetrically scattered, septate, fluid-like, anechoic collections in both breasts that also had transpassed in between the pectoralis muscle fibers (Fig. 1).
case_images: Mediolateral oblique (a) and craniocaudal(b) mammography images of the right and left breasts. Widespread mass opacities covering both breast parenchyma are observed (dashed lines and arrows in A-B).

case_images: Mammography showed dense breast parenchyma and nodular mass-like densities (Fig. 2).
case_images: Axial fat-suppressed T2-weighted (a), axial post-contrast fat-suppressed T1-weighted (b), axial post-contrast subtraction (c), sagittal post-contrast fat-suppressed T1-weighted (d), DWI (diffusion-weighted imaging) (e), ADC (apparent diffusion coefficient) map (f) and silicon-suppressed MRI sequences (g). Septate cystic areas are observed, which are hyperintense on T2-weighted imaging of the filling material and do not show diffusion restriction. These areas extend into the pectoral muscles in both breasts (yellow asterisks in A and D). It was thought that the filling material on the left might be infected because of the rim enhancement in the post-contrast series (red arrows in B).

case_images: The material in the left breast was accompanied by thin rim enhancement (Fig. 3). 3 cc of filler material was aspirated from the left breast, cytological analysis showed basophilic Aquafilling  material surrounded by diffuse inflammatory infiltrates.
