Name of the Patient : Abc Xyzhotlmn / F / 57 yrs.
Referred by : Dr. Abc Xyzhansali.
Examination : M.R.I. of the Right Thigh.

CLINICAL PROFILE :

H/O being operated for a myxoid liposarcoma Grade I on 00.00.00.
For follow-up.

EXAMINATION :

M.R.I. of the right thigh was performed using the following parameters :

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

6 mm thick T1 Weighted sagittal images.

6 mm thick T1 Weighted and STIR coronal images.

OBSERVATION :

There is a post-operative scar in the antero-lateral aspect of the right thigh with susceptibility artifacts. The bulk of the right thigh appears small.

There is seen an ill-defined lesion in the anterior compartment of the right thigh deep to the quadriceps muscles and measures approximately 3.0 x 2.8 x 6.0 cms. This lesion is located approximately 4.0 cms cranially from the right knee joint. This lesion is hyperintense on the T1 Weighted images and is heterogenously hyperintense (predominantly hypointense) on the T2 Weighted and STIR images.



An ill-defined hyperintense area is seen in the right antero-lateral aspect of the vastus lateralis muscle on the T2 Weighted and STIR images and is of intermediate signal intensity on the T1 Weighted images.

Subtle hyperintense signal seen in the vastus intermedius and lateralis muscle on the T2 Weighted images in the right thigh would be due to fatty change.

The visualized portion of the right femur shows normal signal intensity. There is no obvious bone destruction or erosion.

IMPRESSION :

In a known C/O myxoid liposarcoma Grade I, the MRI features are suggestive of :

1. Post-operative status.

2. Altered signal in the right vastus lateralis muscle and in the right vastus intermedius muscle, in some places, in the middle third of the right thigh as described and deep to the quadriceps muscle 6.0 cms cranially from the knee joint, most likely is the sequelae of previous surgery (post-operative fibrosis). The possibility of these signal intensity changes being due to tumor recurrence is less likely.

As compared to the previous MRI (scan no:00005) dated 00.00.00, there is no significant change noted.
