Name of the Patient : Abc Xyzchand Sollmn / M / 40 yrs.
Referred by : Dr. Abc Xyz. Shah.
Examination : M.R.I. of the Right Knee Joint.
CLINICAL PROFILE :
C/O pain in the right knee joint since 1 1/2 years.
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.
5 mm thick GRASS axial images.
There is reduction in the right medial tibio-femoral joint space.
There is a linear, 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 margin. This represents a horizontal flap tear.
The anterior horn of the medial meniscus and the anterior and posterior horns of the 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 :
There is an ill-defined, hyperintense signal on the GRASS and STIR images in the marrow of the proximal tibia. This signal appears hypointense to normal marrow on the T1 Weighted images. A horizontally oriented linear hypointense signal on all the pulse sequences about 2.7 cms distal to the superior articular surface of the tibia may represent a fracture line. An old fracture of the proximal fibula is also noted (scans 104.14/15/16, 108.19).
An ill-defined, hyperintense signal on the STIR and GRASS images is also noted in the lateral femoral condyle.
Irregularity of the articular margin of the medial femoral condyle is noted with subchondral pits/erosions. Irregularity of the articular cartilage overlying the medial femoral condyle is noted.
There is slight reduction in the patello-femoral joint space.
Marginal, fairly large, osteophytes are noted around the articular surfaces of the right femur, tibia and patella. Loose bodies are also noted in the right knee joint which appears hypointense on the GRASS and STIR images.
- 3 - Scan-00006
There is a small right knee joint effusion.
The MRI features suggest osteoarthritic changes involving the right knee joint with :
1. A horizontal flap tear involving the posterior horn of the medial meniscus of the right knee joint.
2. A horizontally oriented fracture line of the proximal tibia with diffused altered signal, probably a stretch fracture.
3. Old fracture of the proximal right fibula with callus formation.
4. Reduction in the medial tibio-femoral joint space with irregularity of the articular cartilage overlying the medial femoral condyle with subchondral bony changes.
5. Small right joint effusion with multiple loose bodies in the right knee joints.
6. Marginal osteophytes around the right knee joint.
