Name of the Patient : Abc XyzShlmn / M / 22 yrs.
Referred by : Dr. Abc Xyzosle.
Examination : M.R.I. of the Left Knee Joint.
CLINICAL PROFILE :
C/O pain with swelling over the left knee joint with click.
EXAMINATION :
M.R.I of the left knee joint was performed using the following parameters :
4 mm thick T1 Weighted, proton and GRASS sagittal images.
4 mm thick T1 Weighted and STIR coronal images.
4 mm thick T1 Weighted and Fast Scan (T2 *) axial images.
OBSERVATION :
Menisci :
There is a linear, hyperintense signal on all the pulse sequences in the posterior horn of the lateral meniscus of the left knee joint extending upto the inferior articular margin. This represents a Grade III meniscal signal (Meniscal tear). This lesion is seen to communicate with an intermediate signal intensity lesion on the T1 Weighted images along its posterior and postero-lateral margins, which turns hyperintense on the GRASS and STIR images and represents a parameniscal cyst. A similar intrameniscal lesion is seen in the anterior horn of the lateral meniscus in communication with a smaller parameniscal cyst along its anterior margin.
The anterior and posterior horns of the medial meniscus reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The posterior cruciate ligament appears buckled but shows normal signal intensity.
The anterior cruciate ligament shows normal contour. An ill-defined signal is seen around the anterior cruciate ligament which may represent a strain.
Collateral Ligaments and the Patellar Tendon :
The medial collateral ligament and the patellar tendon are normal.
The lateral collateral ligament is displaced laterally by the parameniscal cyst.
Hoffas Fat Pad :
The Hoffas fat pad is normal.
Articular cartilage and bones :
The patella is tilted laterally and extends slightly beyond the lateral margin of the lateral femoral condyle.
Minimal fluid is noted in the left knee joint.
The articular cartilage overlying the patella, tibia and femur appears normal.
IMPRESSION :
1. A horizontal tear of the posterior horn of the lateral meniscus of the left knee joint with a parameniscal cyst along its posterior and postero-lateral margin.

- 3 - Scan-00006
2. A smaller, parameniscal cyst along the anterior horn of the lateral meniscus of the left knee joint with a small meniscal tear.
3. Buckling of the posterior cruciate ligament with a partial strain of the anterior cruciate ligament.
4. Lateral tilt of the patella which extends slightly beyond the lateral margin of the lateral femoral condyle (with the knee joint in the extended position).
5. Minimal left knee joint effusion.
