RESUMEN
Breast implants are associated with well-known common complications that have been widely studied, such as rupture and capsular contraction. However, the increasingly growing number of patients with breast implants has led to the increased likelihood of coming across less common complications; these include seromas or late infection; adenopathies in the internal mammary chain; granulomas in the capsule of the implant, which in some cases can extend beyond the fibrous capsule; desmoid tumors associated with the implants; and breast implant-associated large cell anaplastic lymphoma. This article aims to review the main uncommon complications associated with breast implants and to describe and illustrate their findings in different imaging techniques. Proper management of these complications is important; this is especially true of late seroma and the diagnosis of breast implant-associated large cell anaplastic lymphoma for their repercussions.
