case_images: Because of the increased CRP, an infectious process and a magnetic resonance imaging (MRI) were performed, and the suspected diagnosis of OMP was established (Figures 4-6, blue arrows). An abscess of Hoffa's fat pad with circular fat pad infiltration was observed (Figures 4-6, red arrows).
