Name of the Patient : Abc Xyzbai P. Kotlmn / F / 49 yrs.
Referred by : Dr. Abc XyzP. Mehta / Dr. Abc Xyzhah.
Examination : M.R.I. of the Left Knee Joint.
CLINICAL PROFILE :
C/O pain in the left leg and knee with mild swelling since 10-12 days.
M.R.I. of the left knee with tibia-fibular joint was performed using the following parameters :
4 mm thick proton, T1 Weighted and GRASS sagittal images.
5 mmm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
5 mm thick T1 Weighted and STIR coronal images.
There is a linear hyperintense signal on all the pulse sequences in the posterior horn of the medial meniscus of the left knee joint not reaching upto the articular margin. This represents Grade II meniscal signal (meniscal degeneration).
The anterior and posterior horns of the lateral meniscus and anterior horn of the medial meniscus 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 seen an ill-defined, hyperintense signal on the T2 Weighted and GRASS images within the marrow of the proximal third of the left tibia along the endosteum of the subcutaneous aspect of the left tibia. This lesion appears iso to hypointense to normal marrow on the T1 Weighted images. The subcutaneous fat overlying this segment of the tibia also shows a hyperintense signal on the T2 Weighted images. The involved segment is about 9.0 cms distal to the left knee joint.
A bone island is noted in the proximal left tibia.
The articular cartilage overlying the patella, tibia and femur appears normal.
There is no left knee joint effusion.
1. Altered signal in the posterior horn of the medial meniscus of the left knee joint represents Grade II meniscal signal (meniscal degeneration).
2. Altered signal within the marrow of the proximal third of the left tibia (about 9.0 cms distal to the left knee joint) along the endosteum of the subcutaneous aspect of the left tibia and in the overlying subcutaneous fat as described is not specific for a single etiology. This most likely is an inflammatory lesion. The possibility of a traumatic etiology is less likely.
3. A bone island in the proximal left tibia.
