Post-operative Post Irradiation using Ultrasound Breast Tumor

The commonest abnormality is a hematoma, producing a rounded lesion which, in the early stages is , ill defined but which later becomes better defined. Blood clots adjacent to the inner wall of the haematoma may mimic a solid lesion. Associated to this there may be skin thickening, focally increased reflectivity and trabecular distortion, producing quite marked focal attenuation. Eventually a scar results, seen sonographically as a narrow band of attenuation extending down from the skin deeper in the tissue, perhaps persisting trabecular distortion and skin thickening.
