Name of the Patient : Abc Xyz Kalmn / F / 30 yrs.
Referred by : Dr. Abc Xyzngsarkar.
Examination : M.R.I. of the Left Thigh with MRV &
MRA.

CLINICAL PROFILE :

C/O pain with swelling in the lower left 1/3 rd femur since 6 months.
Operated for a ? removal of lipoma from the same region in 0000.

EXAMINATION :

M.R.I. of the left thigh with MRV and MRA was performed using the following parameters :

7 mm thick T1 Weighted and T2 Weighted (with fat saturation) axial images.

5 mm thick T1 Weighted and STIR coronal images.

7 mm thick GRASS sagittal images.

MRV and MRA were performed using 2D TOF sequences.

OBSERVATION :

There is seen fatty replacement in the bulk of the left vastus lateralis muscle and the biceps femoris muscle, distally. These changes are seen over a distance of about 18.0 cms cephalad to the left knee joint.

There are multiple, serpingenous lesions in the bulk of the left vastus lateralis muscle, biceps femoris muscles and in the intermuscular fat plane between these muscles in the anterior and posterior compartments of the distal left



thigh, laterally. These lesions are of intermediate signal intensity on the T1 Weighted images and appear hyperintense on the T2 Weighted and STIR images and extend about 18.0 cms supero-inferiorly, proximal to the left knee joint. There is no bone erosion or destruction noted. The subcutaneous tissue around this lesion are unremarkable. There is no extension of this lesion into the left knee joint space per se.

The rest of the visualized muscles in the distal left thigh are unremarkable.

Scar of previous surgery along the antero-lateral margin of the distal left thigh is noted.

MRV/MRA of the distal left thigh and proximal left leg does not reveal any abnormal vascularity at the site of the lesion. There are no obvious arterial feeder vessels or enlarged draining veins into the venous system identified on this study.

IMPRESSION :

1. Post-operative/post-biopsy status.

2. Serpingenous lesions in the bulk of the left vastus lateralis muscle, left biceps femoris muscle and in the intermuscular fat plane between these muscles in the anterior and posterior compartments of the distal left thigh, laterally, as described, are not specific for a single etiology. This lesion most likely represents an intermuscular/intramuscular hemangioma.

3. No obvious arterial feeder vessels or enlarged draining veins into the venous system are identified on this study.

As compared to the previous MRI dated 00.00.00, there is no significant change noted.
