| Summary: | Background: To determine whether there is correlation between magnetic resonance imaging (MRI) findings and breast elastography to differentiate seroma/hematoma from silicone-induced granuloma of breast implant capsule (SIGBIC). Methods: Prospective study of 99 patients with breast implants submitted to breast MRI during the period from February 1 to May 1, 2017. Patients who present MRI findings of seroma/hematoma or SIGBIC were submitted to a complementary ultrasound elastography study to evaluate the correlation of the results. The criteria adopted for the diagnosis of granuloma by MRI were heterogeneous hypersignal in the T2-weighted sequences, late contrast enhancement, and black drop sign. Lesions that did not enhance after the use of contrast were considered as seroma/hematoma. By elastography, the results were considered positive for granuloma when presented as hard lesions, whereas seroma/hematoma presented as soft lesions. Results: Of the 99 patients evaluated, 15 were included in the study. Of the 15 patients, 9 had solid intracapsular MRI masses, whereas 6 presented collections without contrast enhancement. The complementary elastography study showed correlation with MRI results in all cases of SIGBIC and seroma/hematoma, being elastography able to differentiate lesions from solid to cystic. Conclusions: Elastography of intracapsular masses in breast implants presented results compatible with those found by MRI to differentiate solid lesions from collections.
