Name of the Patient : Abc Xylmn / F / 27 yrs.
Referred by : Dr. Abc Xyzhah.
Examination : M.R.I. of the Pelvis.

CLINICAL PROFILE :

C/O backache radiating to the RLE with paresthesias since 8 days.

EXAMINATION :

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

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

4 mm thick T1 Weighted and STIR coronal images.

7 mm thick T2 Weighted (with fat saturation) sagittal images.

OBSERVATION :

There is an ill-defined, hypointense signal on the T1 Weighted images involving the sacrum on the right and the bodies of the first three sacral segments. This lesion appears hyperintense on the T2 Weighted images and STIR images. Minimal extension of the lesion into the presacral soft tissues is noted on the right. Effacement of the second sacral foramen on the right is noted with encasement of the nerve root at this level. The right sacro-iliac joint per se is not involved. The visualized left sacro iliac joint and the hip joints on either side are unremarkable.

Also seen is a fairly large, approximately 7.0 x 5.0 x 8.0 cms well-defined, intermediate signal intensity mass lesion on the T1 Weighted images in the pelvis between the uterus and the rectum, slightly more to the left of the midline. This lesion appears relatively hyperintense as compared to normal muscle on the T2 Weighted and STIR images. Few cystic/necrotic foci are noted within this lesion. The lesion appears to be separate from the uterus, rectum and the bony pelvis. It is seen to indent the uterus and rectum. The right adnexal region is unremarkable. Minimal fluid is noted around the lesion.
..2/.




The urinary bladder shows normal wall thickness. The left iliac vessels are in close relation to the pelvic mass lesion.

IMPRESSION :

1. Altered signal in the sacrum on the right as described is not specific for a single etiology. Such changes may be seen in :

a. Infective processes like tuberculous osteitis.

b. Neoplasia like round cell tumors.

2. A fairly large 7.0 x 5.0 x 8.0 cms sized mass lesion in the pelvis in the utero-rectal pouch, to the left of the midline as described, is not specific for a single etiology. The differential diagnosis would include :

a. Pedunculated fibroid.

b. Lymphnodal mass.

c. Less likely to represent an ovarian lesion.

d. Desmoid.

Name of the Patient : Abc XyzDabholmn / F / 45 yrs.
Referred by : Dr. Abc Xyzesai.
Examination : M.R.I. of the Left Knee Joint.

CLINICAL PROFILE :

C/O left knee joint pain with clicking and limitation of movement.
Alleged H/O fall 3 months ago.

EXAMINATION :

M.R.I of the left knee joint was performed using the following parameters :

4 mm thick T1 Weighted, proton and GRASS sagittal images.

4 mm thick T1 Weighted and T2 Weighted coronal images.

5 mm thick GRASS axial images.

OBSERVATION :

Menisci

Linear hyperintense signal on all the pulse sequences, not reaching upto the articular surface is noted within the posterior horns of the medial and lateral menisci. This would suggest Grade II signal (meniscal degeneration).

The anterior horns of the lateral and medial menisci reveal normal configuration and signal characteristics.

Cruciate Ligaments :

The anterior and posterior cruciate ligaments show normal contour and signal characteristics.





Collateral Ligaments and the Patellar Tendon :

The medial and lateral collateral ligaments and the patellar tendon are normal.

Hyperintense signal on the T2 Weighted and GRASS images is noted within the soft tissues adjacent to the medial collateral ligament. This would represent soft tissue edema/contusions the result of fall.

Hoffas Fat Pad :

The Hoffas fat pad is normal.

Articular cartilage and bones :

The articular cartilage overlying the patella, tibia and femur appears normal.

Hypointense signal on the T1 Weighted images which turn hyperintense on the T2 Weighted and GRASS images is seen within the lateral femoral condyle and would represent bone edema/contusion.

IMPRESSION :

In the given setting of trauma, the MRI features are suggestive of bone edema/contusions within the lateral femoral condyle on the left side. Altered signal in the soft tissues of the left knee joint medially suggests soft tissue injury.

Date : 00.00.00

Name of the Patient : Abc Xyzillmn / M / 65 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O abnormal behaviour with involuntary movements of the RUE and RLE with slurred speech since 5 months.

EXAMINATION :

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

5 mm thick T1 Weighted, proton and T2 Weighted axial images.

5 mm thick FLAIR coronal images.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There are hypointense areas (isointense to CSF) on the T1 Weighted images, of varying size in the left cerebellar hemisphere, pons, right external capsule, bilateral lentiform nuclei, bilateral thalami and right periatrial region. These are seen to turn hyperintense on the proton and T2 Weighted images and represent lacunar infarcts. The lesion in the right external capsular region may be the sequelae of a previous bleed.

Hyperintense areas are seen on the proton, T2 Weighted and FLAIR images in the periventricular and frontal deep white matter. These are iso to hypointense to normal white matter on the T1 Weighted images and are suggestive of ischemia/infarction.

There is mild fullness of both the lateral ventricles.

The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. The vertebro-basilar system is ectatic.


IMPRESSION :

1. Lacunar infarcts in the left cerebellar hemisphere, pons, right external capsule, bilateral lentiform nuclei, bilateral thalami and in the right periatrial region. The lesion in the right external capsular region may be the sequelae of previous hematoma.

2. Altered signal in the periventricular and frontal deep white matter would represent areas of ischemia/infarction.

OBSERVATION :

Areas of hypointensity on the T1 Weighted images which turn heterogeneously hyperintense on the T2 Weighted images are seen to involve the L5 vertebral body, transverse processes, pedicles, articular pillars, laminae and spinous process. There appears to be a break of its superior cortical endplate.

There is extension of this pathologic process into the paravertebral soft tissues on the right side over the L4 to S1 vertebral levels. Also seen is extension into the anterior and
right lateral epidural space over the L3 to the S1 vertebral level with encroachement into the L4-L5 neural foramina bilaterally and on the right side at the L5-S1 level. There is resultant indentation of the thecal sac over these levels.

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

7 mm thick T1 Weighted and STIR coronal images.

8 mm thick T1 Weighted sagittal images.

OBSERVATION :

The subcutaneous fat in the inguinal regions on either side shows an ill-defined hypointense signal on the T1 Weighted images and which turns significantly hyperintense on the T2 Weighted and STIR images. There is a break in the continuity of the surface of the skin on either side in these regions at about the level of the roof of the acetabulum, suggesting a sinus. The sinus tract on the left side also shows evidence of air. The underlying abdominal wall muscles on the left at the operative site also show an ill-defined hyperintense signal on the T2 Weighted and STIR images. An approximately 2.0 cms diameter sized collection is noted deep to the sinus tract on the left in close relation to the left ilio-psoas muscle (se/im 103.21, 104.6). Another smaller collection is seen in the anterior abdominal wall to the right of the midline at the acetabular roof level (se/im 102/22, 102.23, 103/22 and 103.23).



The urinary bladder shows normal wall thickness. There is no prostatic enlargement noted. The seminal vesicles are unremarkable.

The visualized bony pelvis shows normal signal intensity. The visualized hip joints are unremarkable.

The ischio-rectal fossae on either side appear normal.

There are no abnormally enlarged pelvic lymph nodes identified. No obvious vascular anomaly is noted. There is no free fluid in the pelvis.

IMPRESSION :

Altered signal in the subcutaneous fat in the inguinal regions on either side may represent inflammatory changes, in the given clinical setting. Break in continuity of the skin surface in these regions suggest sinus tracts. Involvement of the anterior abdominal wall muscles on the left is noted with a small collection deep to the anterior abdominal wall muscles to the left and a smaller collection in the anterior abdominal wall, to the right of the midline as described.

OBSERVATION :

There is seen an ill-defined, hypointense signal on the T1 Weighted images in the diaphysis of the proximal third of the left tibia, extending over a 10 cms long segment, approximately 5.0 cms distal to the left knee joint. This lesion appears hyperintense on the T2 Weighted and STIR images. There is no obvious cortical or bone erosion or destruction seen though there is some element of periosteal reaction along the antero-medial margin of the left tibia. The soft tissues overlying the antero-medial margin of the left tibia appear hyperintense on the T2 Weighted and STIR images which may represent inflammatory changes/soft tissue edema.

The zone of transition between the affacted segment and the normal marrow is ill-defined.

The visualized fibula is unremarkable.
