Name of the Patient : Abc Xyzlmn / M / 57 yrs.
Referred by : Dr. Abc Xyzndhi.
Examination : M.R.I. of the Right Knee Joint.
CLINICAL PROFILE :
H/O sudden onset of pain in the right knee joint while climbing stairs 2 months back with subsequent swelling and locking since then.
M.R.I of the right 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 axial images.
There is seen an intrasubstance, hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus of the right knee joint, extending upto the superior articular surface. This represents Grade III meniscal signal (meniscal tear).
A linear hypointense signal is seen in the posterior horn of the lateral meniscus on all the pulse sequences not reaching upto the articular surface would represent Grade II meniscal signal (meniscal degeneration).
The anterior horn of the medial and lateral menisci reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The anterior and posterior cruciate ligaments show normal contour and signal characteristics.
Collateral Ligaments and the Patellar Tendon :
The medial and lateral collateral ligaments and the patellar tendon are normal.
Hoffas Fat Pad :
The Hoffas fat pad is normal.
Articular cartilage and bones :
The articular cartilage overlying the patella and tibia appears normal.
There is a small right knee joint effusion.
There is an ill-defined, hyperintense signal on the T2 Weighted and STIR images in the medial femoral condyle and in medial tibial plateau, adjacent to the medial tibio-femoral joint. This signal appears iso to hypointense to normal marrow on the T1 Weighted images. A well-marginated, focal, hypointense signal on the T1 Weighted images is noted in the subchondral region along the inferior margin of the medial femoral condyle. This lesion appears slightly hyperintense on the T2 Weighted and STIR images. Slight irregularity of the underlying articular cartilage is noted (scans 102.12, 13).
1. Altered signal in the posterior horn of the medial meniscus of the right knee joint, extending upto the superior articular surface represents Grade III meniscal signal (meniscal tear).
- 3 - Scan-00006
2. Small right knee joint effusion.
3. Focal altered signal in the subchondral region along the inferior margin of the medial femoral condyle with slight irregularity of the overlying articular cartilage may represent a subchondral fracture/osteochondritis dessicans.
4. Diffuse altered signal in the marrow of the medial femoral condyle and in medial tibial plateau, adjacent to the medial tibio-femoral joint most likely represents bone bruise.
