MRI Visualization and Distribution Patterns of Foreign Modeling Agents: A Brief Pictorial Review for Clinicians

Figure 5

Magnetic resonance imaging STIR sequence showing different patterns in the breasts, in two patients, with the infiltration of silicone and other substances. Patient 1: it was used silicone, an approximate amount of 1250 ml. (a) Axial plane: there is infiltration by modelling material with a mixed and nodular pattern, with hypointense signal in the superficial portion (white arrows) and a diffuse pattern with hyperintense signal in the deep part of both breasts (white arrowheads); right axillary ganglion with modeling infiltration is also identified. (b) Coronal plane: the hypointense signal’s globular pattern also affects the intermammary region’s subcutaneous cellular tissue (white arrows). Patient 2: it was a mixture of mineral oil, car’s oil, and silicone, with an approximate amount of 2000 ml. (c) Axial plane: a globular pattern of hyperintense signal is observed (white arrows), associated with diffuse hyperintensity changes due to diffuse infiltration in both breasts. (d) Coronal plane: globular pattern of hyperintense signal predominantly in the left breast (white arrow).
