Name of the Patient : Abc Xyz G. Wadhlmn / F / 50 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Left Knee Joint.
CLINICAL PROFILE :
Alleged H/O injury to the left thigh with twist of the left knee joint on 00.00.00.
H/O 2-3 episodes of sudden give way of the left knee joint since then.
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.
5 mm thick Fast Scan (T2 *) axial images.
There is a horizontally oriented linear, hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus of the left knee joint reaching upto the inferior articular margin. This most likely represents a horizontal flap tear.
The anterior and posterior horns of the lateral meniscus and the anterior horn of the medial meniscus reveal normal configuration and signal characteristics.
Cruciate Ligaments :
The anterior cruciate ligament is ill-defined and shows a hyperintense signal on the GRASS images along its course. The tibial attachment of the anterior cruciate ligament appears slightly attenuated. A hypointense area on the T1 Weighted images which turn hyperintense on the STIR and GRASS images is seen in the region of the attachment of the anterior cruciate ligament (? avulsions ? subchondral cyst).
The posterior cruciate ligament shows 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 unremarkable.
Articular cartilage and bones :
There is an ill-defined hyperintense signal on the GRASS and STIR images in the subchondral region in the lateral femoral condyle and in the lateral tibial plateau adjacent to the left tibio-femoral joint. This lesion appears hypointense on the T1 Weighted images and would represent bone bruise in the given clinical setting. Minimal subchondral depression of the lateral femoral condyle, antero-laterally is also noted (se/im 102.15, 105.10). ..3/.
- 3 - Scan-00002
There is an ill-defined, hyperintense signal on the GRASS and STIR images in the soft tissues along the posterior margin of the proximal left tibia at the level of the tibio-fibular joint. This may represent soft tissue contusion, in the given clinical setting.
A small left knee joint effusion is noted.
1. A horizontal flap tear of the posterior horn of the medial meniscus of the left knee joint.
2. Changes in the anterior cruciate ligament may suggest a partial tear (? avulsion at its tibial attachment).
3. Bone bruise in the subchondral region in the lateral femoral condyle and in the lateral tibial plateau adjacent to the left tibio-femoral joint with a subchondral depression/fracture in the lateral femoral condyle, antero-laterally.
5. A small left knee joint effusion with probable soft tissue contusion along the posterior margin of the proximal left tibia.
