Tomosynthesis revealed a lower inner partially circumscribed lesion which proved by ultrasound well-defined complicated cystic lesion with internal echo debris (postoperative seroma likely hemorrhagic), the lesion was categorized as (BIRADS 3).MRI d Axial T1 weighted image e Axial T2 weighted image f Post-contrast subtraction T1 weighted image proved to be well-defined complicated cystic lesion with internal content eliciting high signal in T1 and T2 with faint post-contrast enhancement ( postoperative seroma likely hemorrhagic), the lesion was categorized as (BIRADS 3). FNAC revealed hemorrhagic fluid
