[|AI|]  Dear friend Heterogeneous bone marrow signal means that on MRI means that the signal from the marrow was not of normal character, it is usually an incidental finding but in some it may be some malignancy is discovered, and as per recommendation of one study an oncology consult is warranted. The rest of the findings are consistent with posterior cruciate ligament and cartilage damage with initial osteoarthritic findings.
