Case 16:   Metastasis - Breast Cancer

Diagnostic Category:

Clinical Presentation:

71 year old woman with metastatic breast carcinoma following treatment.

CT: Ring of fibrotic tumor stroma

Imaging Findings:

CT demonstrates central hypodense tumor necrosis and ring enhancement on the 10 minute delayed phase indicating desmoplastic stroma reaction (fibrosis). In this case as a effect of treatment. However more peripheral washout of the lesions on delayed images represents viability of malignancy.

Note subtle capsular retraction due to the metastasis in segment 4A (first two images).
