Name of the Patient : Abc Xyzlmn / F / 33 yrs.
Referred by : Dr. Abc Xyzshi.
Examination : M.R.I. of the Left Knee Joint.

CLINICAL PROFILE :

H/O fall 6 months back with pain and swelling over the left knee joint since then.

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 (with fat saturation) coronal images.

4 mm thick T1 Weighted and GRASS axial images.

OBSERVATION :

There is evidence of an area of hypointensity on the T1 Weighted images which turns hyperintense on the T2 Weighted and GRASS images in the region of Hoffas pad and posterior to the quadriceps tendon. This most likely represents synovial thickening. A few areas of hypointensity on the GRASS images are also seen within this lesion. Slight effusion is seen within the left knee joint.

A linear hyperintense signal, not reaching upto the articular surface is seen within the posterior horn of the medial meniscus. This would represent Grade I meniscal signal (degeneration).






The anterior and posterior cruciate ligaments and the rest of the menisci are unremarkable. The visualized femur, tibia and patellar are unremarkable.

IMPRESSION :

The MRI features are suggestive of synovial thickening around the left knee joint as described. Pigmented villo nodular synovitis may be considered.

A contrast enhanced scan may be worthwhile.

C/O backache since 3 months with radiation of pain to the RLE and paresthesias.

EXAMINATION :

M.R.I of the lumbo-sacral spine was performed using the following parameters :

5 mm thick T1 Weighted and T2 Weighted sagittal images.

5 mm thick T1 Weighted and T2 Weighted axial images.

OBSERVATION :

There is sacralization of the L5 vertebra and the L4 vertebra is as marked on the film. Please correlate with plain radiographs.

There is loss of water content of the D12-L1 and L2-L3 intervertebral discs.

There is a transepiphyseal herniation of the L2-L3 disc through the antero-superior margin of the L3 vertebral body. The L3 vertebral body adjacent to the L2-L3 disc appears hypointense on the T1 Weighted images and hyperintense on the T2 Weighted images.

Minimal posterior disc bulges are noted at the L2-L3 and L4-L5 levels.

The rest of the lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The facet joints and the visualized pre and paravertebral soft tissues are unremarkable.

The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

15.0 mm at L1-L2
15.0 mm at L2-L3
15.0 mm at L3-L4
11.0 mm at L4-L5
10.0 mm at L5-S1.

Name of the Patient : Abc Xyzbai Blmn / F / 65 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Dorsal Spine.

CLINICAL PROFILE :

C/O backache with weakness in BLE since March 0000. D8 to D10 decompressive laminectomy with drainage of paravertebral abscess done 20 days back.

EXAMINATION :

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

4 mm thick T1 Weighted and T2 Weighted sagittal images.

7 mm thick T1 Weighted and T2 Weighted axial images.

OBSERVATION :

There is evidence of laminectomy over the D7 to D11 levels with post-operative changes in the soft tissues in the posterior dorsal region over these levels.

There is an ill-defined, hypointense signal on the T1 Weighted images in the D8, D9 and D10 vertebral bodies, more to the left of the midline. This signal, however, appears isointense to slightly hyperintense on the T2 Weighted images. The D8-D9 intervertebral disc is slightly more hyperintense on the T2 Weighted images.

The dorsal spinal cord over the D6 to D11 vertebral levels appears hypointense to normal cord on the T1 Weighted images and is hyperintense on the T2 Weighted images. Its margins are slightly irregular.






The rest of the visualized dorsal vertebral bodies and the remaining intervertebral discs are unremarkable. The visualized pre and paravertebral soft tissues are unremarkable.

There is no extrinsic cord compression.

The conus medullaris terminates at the L1 level.

Screening, T1 Weighted sagittal images of the lumbo-sacral spine reveals Grade I spondylolisthesis of the L5 over the S1 vertebra with probable spondylolysis of L5.

IMPRESSION :

1. Post-operative status.

2. Altered signal of the D8, D9 and D10 vertebral bodies and D8-D9 intervertebral disc may be the sequelae of previous osteitis and discitis.

3. Altered signal in the dorsal spinal cord over the D6 to D11 vertebral levels may represent cord edema/ischemia/? myelomalacic changes or syrinx.

The previous scans were not available for comparison.

Name of the Patient : Abc Xyz Nlmn / F / 46 yrs.
Referred by : Dr. Abc Xyzisheri.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O right hemiparesis with altered sensorium and fever since 4 days.

EXAMINATION :

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

5 mm thick T1 Weighted and T2 Weighted axial images.

5 mm thick FLAIR coronal images.

5 mm thick T1 Weighted sagittal images.

Limited MR Venogram sequence was obtained in the coronal plane.

SOME SCANS SHOW PATIENT MOTION.

OBSERVATION :

There are ill-defined, hyperintense areas on the T2 Weighted and FLAIR images in the frontal regions bilaterally, left posterior parietal region and to a much lesser extent in the right posterior parietal region. These lesions appear predominantly hypointense on the T1 Weighted images and are seen to involve the cortex and subcortical white matter. There is a hyperintense focus on all the pulse sequences within the left frontal region which represents subacute haemorrhage. There is resultant effacement of the sulcal spaces with mild indentation and inferior displacement of the left lateral ventricle by the lesion in the left posterior parietal region.

Both the lateral, third and the fourth ventricles are otherwise unremarkable. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.


The superior sagittal sinus and partly the left transverse sinus do not show the normal flow void signal. In place, there is a hyperintense signal on all the pulse sequences within the above mentioned dural venous sinuses which represent a thrombus.

Limited MR Venogram reveals absence of normal flow signal in the superior sagittal sinus and a thin streak in the left transverse sinus. The left sigmoid sinus is well-visualized. The right transverse and sigmoid sinuses are not well-visualized (? hypoplasia). The internal cerebral veins, vein of Galen and straight sinus are unremarkable.

IMPRESSION :

The MRI features described above suggest superior sagittal and left transverse sinus thrombosis with altered signal in the frontal regions and posterior parietal regions bilaterally, which most likely represent venous infarcts. The left frontal lesion shows evidence of haemorrhage.
