Name of the Patient : Abc Xyz Plmn / F / 17 yrs.
Referred by : Dr. Abc Xyzhrivastav.
Examination : M.R.I. of the Lower End of Right
CLINICAL PROFILE :
C/O pain and swelling over the lower end of the right femur since 3-4 months.
Histopathology s/o chondrosarcoma. Operated for the same on 00.00.0000.
M.R.I. of the lower end of right femur was performed using the following parameters :
5 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
4 mm thick T1Weighted and STIR coronal images.
4 mm thick T1 Weighted and T2 Weighted (with fat saturation) sagittal images.
Vitamin E capsules were placed as markers at the site of swelling.
There is a large mass lesion in the posterior compartment and along the medial margin of lower one third of the right femur which measures approximately 6.0 x 3.3 x 5.8 cms. This lesion is hypointense to normal muscle on the T1 Weighted images and turns hyperintense on the T2 Weighted and STIR images. Few areas show lobulated appearance with presence of septae. There is protuberance along the antero-medial margin of the distal femoral diaphysis, with a
broad base. The above described mass lesion is seen to cap this protuberance. The marrow in the lower one third portion of the right femur shows hyperintense areas on the T2 Weighted and STIR images which is hypointense to normal marrow on the T1 Weighted images. The soft tissues and the fat in the popliteal region is irregular. There is displacement of the popliteal vessels postero-laterally.
The vastus medialis muscle show a hyperintense signal on the T2 Weighted and STIR images. Susceptibility artefacts are noted in the vastus medialis muscle.
Protuberance along the antero-medial margin of the distal diaphysis of the right femur may represent an osteochondroma. Soft tissue along the medial and postero-medial margin of the distal right femur may represent chondrosarcoma (probably arising from the cartilagenous cap).
The plain radiographs were not available for review.
