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

Figure 7

STIR sequence magnetic resonance shows three planes to describe the infiltration and migration of the modeling agent to the ischiorectal fossa. The substance used by this patient was biopolymers and an approximate amount of 1000 ml. (a) Axial plane: infiltration by modeling material with a diffuse pattern that infiltrates the gluteus maximus muscles (white arrowheads) with migration towards the ischiorectal fossa. (b) Coronal plane: the affection by modeling material is presented in the subcutaneous cellular tissue (white arrows). (c) Sagittal plane: identifying migration of the modeling material towards the lumbar region (long white arrow).
