Sample Knee MRI Medical Transcription Report

MRI OF THE RIGHT KNEE

CLINICAL HISTORY:  Work injury.

Multiplanar sagittal, axial, and coronal images were obtained through the right knee without contrast administration. Images through the osseous structures do show abnormal signal involving the medial femoral condyle. This is most consistent with a bone contusion. Articular cartilage does not appear affected. No findings of any cortical irregularity to suggest a fracture. There is a moderate joint effusion. Images through the anterior and posterior cruciate ligaments show normal signal characteristics and contour without evidence of a tear. The posterior horn of the medial meniscus shows diffuse, increased signal change consistent with a mixed or degenerative-type process. No findings of any abnormal linear signal to communicate with the articulating surface to suggest a tear. Anterior horn is preserved. The lateral meniscus is preserved in contour and signal. The coronal images through the collateral ligaments fail to fully trace the lateral collateral ligament. This suggests a complete tear. Some widening and fraying of the medial collateral ligament indicating perhaps partial tear.

IMPRESSION: Bone contusion involving the medial femoral condyle. Diffuse, mixed, or degenerative-type changes involving the posterior horn of the medial meniscus. Probable complete tear of the lateral collateral ligament whose course cannot be fully traced on the coronal images. Suggestion of partial tear involving the medial collateral ligament. Joint effusion as might be anticipated.

MRI OF THE RIGHT KNEE

HISTORY:  Pain.

Multiplanar images were obtained. The PCL is intact. The ACL appears to be intact but with increased signal. Injury to the ACL is not excluded. There is a linear area of increased signal involving the posterior horn of the medial meniscus that does touch upon the inferior articular surface consistent with a tear. The menisci are otherwise unremarkable. The collateral ligaments are intact. There is a medial suprapatellar joint effusion with plica within it. There are cysts posterolateral to the knee joint as well as posterior and superior to the PCL, as well as anterior to the tear, in the posterior horn of the medial meniscus. Marrow signal within the bony structures is unremarkable. There are some lateral and medial osteophytes. There is marked medial compartment narrowing.

IMPRESSION:
1.  Tear, posterior horn of the medial meniscus that touches upon the inferior articular surface.
2.  Medial suprapatellar joint effusion with plica within it.
3.  Some cysts posterolateral to the knee, posterior, superior to the posterior cruciate ligament, as well as some fluid anterior to the tear of the posterior horn of the medial meniscus.
4.  Overall, the anterior cruciate ligament appears to be grossly intact but with increased signal. Partial injury to the anterior cruciate ligament is not excluded.
5.  There are some retropatellar osteophytes as well.

MRI OF THE RIGHT KNEE

Multiplanar images were obtained. The PCL is intact. There is no normal-appearing ACL. There is increased signal in the area of the ACL. This is suggestive of a tear of the ACL. Marrow signal within the bony structures is unremarkable. There is globular increased signal of the posterior horn of the medial meniscus. There does appear to be a component of this meniscus that is linear and touches upon the superior articular surface on one image and inferior articular surface on the next, for which a complex tear is not excluded. There is some fluid surrounding the posterior horn of the medial meniscus as well. The menisci otherwise are unremarkable. There is a large suprapatellar joint effusion. The collateral ligaments appear grossly intact.

IMPRESSION:
1.  No normal-appearing anterior cruciate ligament, suggestive of a tear of the anterior cruciate ligament. There is increased signal in the area of the anterior cruciate ligament.
2.  Suprapatellar joint effusion.
3.  Abnormal appearance of the posterior horn of the medial meniscus suggestive of an acute tear superimposed on some degenerative change.
