Name of the Patient : Abc Xyz. Almn / M / 70 yrs.
Referred by : Dr. Abc Xyznshah.
Examination : M.R.I. of Both Hips.

CLINICAL PROFILE :

C/O pain in the left hip region since 1 month.

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 axial images.
5 mm thick Proton density sagittal images.

OBSERVATION :

There are well-marginated, geographical areas following fat signal characteristics on all the pulse sequences in the head of the left femur. The left femoral head shows loss of normal contour. The double line sign is well-identified. The neck of the left femur and the left acetabulum reveal an ill-defined hypointense signal on the T1 Weighted images which appears hyperintense on the T2 Weighted and STIR images. No obvious break in the cortex is noted. A small left hip joint effusion is noted. The articular cartilage overlying the left femoral head appears thinned out posteriorly. Slight atrophy of the left gluteal muscles in relation to the right is noted.

A well-marginated area following fat signal characteristics on all the pulse sequences is noted in the head of the right femur, which shows normal contour. The right femoral neck, right acetabulum and the articular cartilage overlying the right femoral head are unremarkable. There is no right hip joint effusion.

The pelvic bones and femora show spotty fatty changes suggesting osteoporosis.

IMPRESSION :

1. Class A avascular necrosis of the left femoral head with a small left hip joint effusion. Altered signal in the left acetabulum and neck of the left femur may represent bone bruise/edema.

2. Class A avascular necrosis of the right femoral head.
