Name of the Patient : Abc Xyzesh R. Dulmn / M / 19 yrs.
Referred by : Dr. Abc Xyzudhat / Dr. Abc Xyzadhav.
Examination : M.R.I. of the Right knee with lower Thigh.
CLINICAL PROFILE :
C/O pain and swelling over the right thigh since 2 years.
M.R.I. of the right knee with lower thigh was performed using the following parameters :
5 mm thick GRASS axial images.
4 mm thick T1 Weighted, Proton and GRASS sagittal images.
4 mm thick T1 Weighted and STIR coronal images.
There is evidence of a well-defined mass lesion just anterior to the shaft of the lower third of the right femur. Its inferior aspect is seen to be located at a distance of approximately 8.0 cms from the right knee joint. This lesion is seen to measure approximately 4.0 x 2.0 x 1.3 cms and is located deep to the vasti muscles and the quadriceps tendon.
This lesion is near isointense to normal muscle on the T1 Weighted images and turns hyperintense on the T2 Weighted, STIR and GRASS images. There is indentation upon the quadriceps tendon and muscle. There is no bony erosion or destruction. There is no periosteal reaction on this scan.
There is prominence of the deep and superficial veins of the visualized right thigh.
A linear hyperintense signal is seen within the posterior horn of the medial meniscus and may represent Grade II meniscal signal (meniscal degeneration).
The rest of the visualized portion of the right femur per se shows normal signal intensity.
The MRI features are suggestive of a mass lesion anterior to the shaft of the right femur measuring approximately 4.0 x 2.0 x 1.3 cms as described. This is not specific for a single diagnosis. The differential diagnosis may include,
1. A neoplasm like a nerve sheath tumor.
2. A Ganglion cyst.
3. A cavernous angioma (less likely).
4. Fluid filled suprapatellar bursa (less likely).
5. Synovial cell sarcoma (less likely).
