“…A fat-fluid level may be present [33]. In post-contrastographic images, FN shows several degrees of enhancement, depending on the stage (acute or chronic) of the inflammatory process [32]. More recent lesions present with irregular contours and may have variable enhancement surrounding the lesion, while older lesions show marked irregularity, retraction, and fibrosis, and generally do not enhance [32].…”

“…In particular, T1-weighted fat-suppressed sequences are helpful to differentiate fat from blood which also shows high-signal intensity on T1-weighted images [30]. As fat-containing lesions are extremely uncommon in malignant conditions, the presence of fat is extremely useful for differentiating FN from a malignant lesion [31,32]. A fat-fluid level may be present [33].…”

“…In 2009, the American Society of Plastic Surgeons (ASPS) Fat Graft Task Force assessed the efficacy of the procedure in 283 patients, documenting only 37 (12.7%) complications, the most frequent being liponecrosis in 16 (5.7%) cases [39]. The main diagnostic difficulties in evaluating patients having undergone breast lipofilling after BOS are mainly related to FN [32]. Patients may clinically present with palpable and painful mammary swelling, and the mammographic and US imagines may be misleading.…”

Breast-oncoplastic surgery, allowing local tumor control and a better cosmetic outcome, is oncologically safe when applied to early-stage breast cancer. Breast cancer recurrence following conservative therapy may occur during the first 5 years after treatment, with a peak incidence after 2 years. Therefore, during the follow-up period, patients undergo a series of ultrasound (US) and mammographic examinations. However, after surgery and radiation therapy, several modifications occur in the treated breast, causing difficulties in image interpretation, especially when local recurrence is suspected. Although not included in routine follow-up, magnetic resonance imaging (MRI) is often used in clinical practice, being considered more sensitive than the conventional imaging examinations in discriminating between postsurgical tissue modifications and tumor recurrence. In this review article, we analyze expected and pathologic breast MRI findings after conservative oncoplastic surgery compared to US and mammographic findings in order to distinguish local recurrence and avoid potential pitfalls in image interpretation.

“…The presence of fat, which is typically hyperintense in T1-weighted sequences, together with the patient's clinical history, can help to rule out a neoplasm and diagnose fat necrosis (18). (Ganau et al, 2009;Taboada et al, 2009;Tan et al, 2005). Fig.…”

Fat necrosis (FN) of the breast is a benign nonsuppurative inflammatory process of the adipose tissue. The radiologic appearance ranges from benign to suspicious for malignancy; therefore, it is very important to know the distinguishing radiologic features of FN on different modalities. Mammography is more helpful in identifying FN than ultrasonography in most of the cases, and MRI may also be used to rule out malignancy as an adjunct to mammography and sonography. Even when modern diagnostic modalities are used, biopsy may still be unavoidable for some cases. In conclusion, an accurate history and familiarity with the radiologic findings are crucial to recognizing FN and avoiding unnecessary interventions.
