Unusual findings on MRI of patients with breast implants

▪ ABSTRACT

Introduction:

Breast prosthesis implantation is one of the most performed surgeries in the world. Over time, different materials were used to reconstitute breast volume. Despite technical and surgical improvements and the safety of current implants, patients are faced with potential “unusual” complications: intracapsular and extracapsular ruptures, late hematomas and contour deformity, intra-nodal silicone, or herniation of the fibrous capsule. Magnetic resonance imaging (MRI) is the most useful imaging modality for investigating these complications.

Method:

This is a series of cases in which so-called “unusual” changes were reported, due to their low frequency or lack of mention in the literature, after surgeries to include a silicone prosthesis. The data were collected from the personal experience of one of the authors in his private clinic, in the city of Brasília-DF, between April 2015 and March 2023.

Results:

A total of 211 patients were evaluated, and less frequent changes were found in the MRI of 12 patients (5.68%), of which: 5 with a large amount of pericapsular fluid, 3 with capsular granuloma, 1 late seroma with hemorrhagic content, 1 intra and extracapsular rupture, 1 nodule close to the implant’s fibrous capsule, 2 axillary lymph node disease ipsilateral, 1 intra-nodal silicone, 1 pectoral muscle edema, 2 desmoid tumor and 1 herniation of the fibrous capsule.

Conclusion:

It is estimated that there are 50 million women with breast implants in the world. Based on this data, the number of so-called “unusual” complications becomes a diagnostic challenge for the plastic surgeon and radiologist.
