Inflammatory breast carcinoma and locally advanced breast carcinoma: characterisation with MR imaging

Abstract

IBC is a distinct clinical and pathological entity resulting in typical MR imaging features. Skin changes (thickening, oedema, enhancement) related to neoplastic involvement of the dermal lymphatics are suggestive of IBC and should prompt a skin biopsy to confirm or rule out the diagnosis.

What Radiologists Need to Know about Diagnosis and Treatment of Inflammatory Breast Cancer: A Multidisciplinary Approach

“…MR imaging findings of IBC differ from those of LABC as follows: nonmasslike enhancement (73% for IBC versus 40% for LABC), skin thickening (53% versus 27%), skin edema (87% versus 27%), and skin enhancement (33% versus 7%) (26). Additional imaging findings that occur more frequently with IBC than LABC include diffuse edema and prepectoral or intramuscular pectoral edema; diffuse cutaneous or subcutaneous and prepectoral high signal intensity on T2-weighted images indicating edema may increase the specificity for IBC (27,28).…”

“…Common findings of IBC on contrast-enhanced MR images are extensive or segmental nonmasslike enhancement and diffuse skin thickening (Fig 8) (20,(25)(26)(27). MR imaging findings are classified according to the BI-RADS lexicon (21).…”

Malignant Mastitis

“…Meme MRG'de LİMK ile karşılaştırıldığında İMK'de daha fazla kitlesel olmayan kontrastlanma (İMK: %73, LİMK: %40), deride kalınlaşma (İMK: %53, LİMK: %27), deride ödem (İMK: %87, LİMK: %27) ve deride kontrastlanma (İMK: 33, LİMK: %7) izlenir [16]. Diffüz meme ödemi, prepektoral veya intramuskuler ödem, diffüz deri ve deri altı ödeme ikincil T2 ağırlıklı görüntülerde sinyal artışı izlenmesi de İMK tanısını destekler [3,17].…”
