Knee pain Note that metallic susceptibility artifact overlies the medial and anterior soft tissues of the knee which represents the radiopaque foreign body seen on prior radiographs.MENISCI: Note that the anterior horn of the medial meniscus is obscured secondary to the susceptibility artifact. The visualized portion of the anterior horn is otherwise intact and there is no evidence of medial or lateral meniscal tear.ARTICULAR CARTILAGE AND BONE: There is a diffuse intermediate signal intensity of the marrow on T1 sequences reflecting chronic changes of sickle cell disease. The articular cartilage of the medial, lateral, and patellofemoral compartments is preserved. LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
No evidence of internal derangement of the knee. Note that the anterior horn of the medial meniscus is obscured due to susceptibility artifact from known foreign body but within these limits, there is no discrete meniscal tear.
