Name of the Patient : Abc Xyz L. Glmn / M / 40 yrs.
Referred by : Dr. Abc Xyzar.
Examination : M.R.I. of Both Hips.
CLINICAL PROFILE :
C/O pain in the right hip region since 6 months.
EXAMINATION :
M.R.I of both hips was performed using the following parameters :
5 mm thick T1 Weighted and STIR coronal images.
5 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.
5 mm thick Proton density sagittal images.
OBSERVATION :
There is loss of normal contour of the right femoral head with
supero-lateral subluxation.
There is a subchondral hypointense lesion on the T1 Weighted images in the antero-superior quadrant of the right femoral head which appears hyperintense on the T2 Weighted images. A small, femoral herniation pit is noted along the medial margin of the right femoral neck. The articular cartilage over the right femoral head is not well-identified. Marginal osteophytes are noted around the right femoral head. An osteophyte is noted along the lateral margin of the right acetabulum which shows a hypointense signal on the T1 Weighted images which turn hyperintense on the T2 Weighted images. A small subchondral cyst is noted in the right acetabulum. There is no right hip joint effusion. The muscles around the right hip joint appear atrophied as compared to the left.
There is a well-marginated, fat signal intensity area on all the pulse sequences in the antero-superior quadrant of the left femoral head. A peripheral hypointense rim with an internal hyperintense rim on the T2 Weighted images on all the pulse sequences is noted around the lesion. The articular cartilage overlying the left femoral head is unremarkable. The left acetabulum appears normal. There is no left hip joint effusion.
IMPRESSION :
1. Class A avascular necrosis of the left femoral head.
2. Changes described in the right hip joint suggest osteoarthritic (? secondaries) changes. Focal altered signal in the antero-superior quadrant of the right femoral head may represent a subchondral cyst.
