Name of the Patient : Abc Xylmn / M / 22 yrs.
Referred by : Dr. Abc Xyzhari.
Examination : M.R.I. of the Pelvis.

CLINICAL PROFILE :

C/O swelling in the left inguinal region with pain in the LLE since 1 year.

EXAMINATION :

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

10 mm thick T1 Weighted and T2 Weighted axial images.

9 mm thick T1 Weighted and STIR coronal images.

9 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is destruction of the acetabular component of the left iliac bone, left pubic bone and partially, the left ischial bone. The remnant of the acetabular component of the left iliac bone and ischial bones appear relatively hypointense when compared to the normal marrow on the T1 Weighted images and appears hyperintense on the T2 Weighted and STIR images. There is seen a fairly large, approximately 16.0 x 16.0 x 21.0 cms sized, lobulated intermediate signal intensity mass lesion extending from the level of the true pelvis through the inguinal region into the proximal left thigh, medially. This lesion appears heterogeneously hyperintense on the T2 Weighted and STIR images but is predominantly hypointense on the T2 Weighted images. The pelvic structures including the urinary bladder and the rectum are seen to be displaced to the right. The muscles in the left inguinal region and the proximal left thigh are displaced laterally. The left iliac and femoral vessels are draped along the antero-lateral margin of the lesion. The left ilio-psoas muscle is along the left lateral margin of the lesion. There is extension into the left hip joint per se. A small left hip joint effusion is also noted. In the proximal left thigh the lesion is seen medially and posteriorly.

The visualized left femoral head and neck are unremarkable. There are no abnormally enlarged lymph nodes identified in the visualized pelvis.

Atrophy of the muscles around the left hip joint is noted.

IMPRESSION :

A fairly large, approximately 16.0 x 16.0 x 21.0 cms sized, heterogeneous signal intensity mass lesion in the pelvis extending into the proximal left thigh, with destruction of the left iliac, pubic and ischial bones as described, is not specific for a single etiology. A sarcomatous lesion (? chondrosarcoma) may be considered as a differential diagnosis. Involvement of the left hip joint is also noted.
