Case History: 54-year-old female with large palpable breast mass filling most of the left breast.
54-year-old female with large palpable breast mass filling most of the left breast.
Figure 1. Axial T1WI shows large well-defined lobular circumscribed heterogeneous signal intensity left breast mass, mainly low signal and perifocal edema is visible in posterior lateral margin. No cystic changes or hemorrhagic bright signal in T1WI. No axillary LNs enlargement at other levels.
Figure 2. Sagittal T1WI shows large well-defined lobular circumscribed heterogeneous signal intensity left breast mass, mainly low signal and perifocal edema is visible in posterior lateral margin. No cystic changes or hemorrhagic bright signal in T1WI. No axillary LNs enlargement at other levels.
Figure 3. No chest wall invasion in axial T1FS post-contrast.
Figure 4. Dynamic time intensity curve shows heterogeneous moderate enhancement and benign features rapid progressive uptake curve.
Diagnosis: Benign phylloid tumor of the breast
Phylloid tumor is a large, rapidly growing circumscribed mass without calcifications.
The appearance of these breast tumors, especially small lesions, on sonography and mammography usually does not allow the distinction of a fibroadenoma and a phylloid breast tumor that needs therapy.
There are no reliable mammographic or sonographic criteria by which to differentiate benign from malignant phylloid tumors.
