Reason: right knee pain after fall MENISCI: The anterior and posterior horns of the medial and lateral menisci are intact. Note is made of a prominent interface of the meniscofemoral ligament of Wrisberg with the posterior horn of the lateral meniscus, resulting in what we believe to be a pseudotear.ARTICULAR CARTILAGE AND BONE: The articular cartilage appears normal. There is geographic curvilinear signal abnormality containing fat within the distal femoral metastasis and proximal tibial metadiaphysis likely representing peculiar islands of red marrow or perhaps areas of chronic osteonecrosis.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL
1. No acute injury.2. Bone marrow signal abnormalities suggestive of peculiar islands of red marrow or perhaps chronic osteonecrosis.
