5 mm thick T1 Weighted and Fast Scan (T2 *) axial images.

OBSERVATION :

There is reduction in height and loss of water content of the cervical intervertebral discs.

There is slight anterior translation of nearly all the proximal cervical vertebrae over the corresponding distal vertebra.

There is invagination of the odontoid process through the foramen magnum with resultant indentation on the cervico-medullary junction. The peridental fat is not well identified. Intermediate signal intensity lesion is noted in the peridental region on the T1 Weighted images which appears hyperintense on the T2 Weighted and Fast Scan (T2 *) images.

Small posterior peridiscal osteophytes are noted in the cervical region. There is also ligamentum flavum hypertrophy at the C1-C2, C2-C3, C3-C4, C4-C5 and C6-C7 levels with resultant effacement of the posterior subarachnoid space.


Type III degenerative marrow changes are noted adjacent to the C2-C3, C3-C4 and C6-C7 intervertebral discs.

The rest of the cervical vertebral bodies show normal signal intensity. The joints of Luschka and the visualized pre and paravertebral soft tissues are unremarkable.

The cervical spinal cord reveals normal signal intensity.

The left vertebral artery appears hypoplastic.

IMPRESSION :

1. Slight anterior translation of nearly all the proximal cervical vertebrae over the corresponding distal vertebra.

2. Basilar invagination with tip of the odontoid process indenting the cervico-medullary junction.

3. Altered signal in the peridental region may either represent pannus or degenerative fibrous tissue.

4. Small posterior peridiscal osteophytes are noted in the cervical region with ligamentum flavum hypertrophy at the C1-C2, C2-C3, C3-C4, C4-C5 and C6-C7 levels.

These changes may either be the sequelae of rheumatoid arthritis with secondary degenerative changes or may be primarily degenerative in etiology.

5 mm thick T1 Weighted and T2 Weighted axial images.

OBSERVATION :

There is near complete collapse of the D5 vertebral body with an angular kyphus at that level.

The D4, visualized D5, D6, D7 and D8 vertebral bodies show an ill-defined, hypointense signal on T1 Weighted images which turn hyperintense on the T2 Weighted images. The intervening intervertebral discs are unremarkable.

There is seen an intermediate signal intensity mass lesion on the T1 Weighted images in the prevertebral region extending over the D2 to D9 vertebral levels. This lesion appears hyperintense on the T2 Weighted images and most likely represents an abscess. Few septae are seen within this lesion. Anterior displacement of the trachea, oesophagus and the great vessels is noted. Similar lesion is noted in the epidural space, circumferentially at the D4 and D5 vertebral levels and into the corresponding neural foramen at these levels. The dorsal spinal cord at these levels however show normal signal intensity.



The rest of the visualized dorsal vertebral bodies and intervertebral discs reveal normal signal intensity. The facet joints are unremarkable.

The conus medullaris terminates at the L1-L2 level.

IMPRESSION :

Near complete collapse of the D5 vertebral body with altered signal of the D4 to D8 vertebral bodies as described, most likely represents osteitis, probably tuberculous osteitis. Prevertebral and epidural soft tissue lesion may represent an abscess.

There is no significant cord compression or cord signal alteration noted.

The possibility of a neoplasm like a small cell tumor seems unlikely.

Name of the Patient : Abc XyzSinlmn / F / 26 yrs.
Referred by : Dr. Abc Xyzmpat / Dr. Abc Xyzdar.
Examination : M.R.I. of the Sella & Perisellar Region.

CLINICAL PROFILE :

C/O amenorrhea.
Serum Prolaction level = 41ng.

EXAMINATION :

M.R.I of the sella and perisellar region was performed using the following parameters :

3 mm thick T1 Weighted and T2 Weighted coronal images.

3 mm thick T1 Weighted sagittal images.

The brain was screened with 5 mm thick T2 Weighted axial images.

After contrast administration, 3 mm thick T1 Weighted coronal, sagittal and axial images (with magnetization transfer) were obtained and 5 mm thick T1 Weighted axial images with magnetization transfer were obtained through the brain.

Delayed 3 mm thick T1 Weighted coronal images were also obtained through the sella.

OBSERVATION :

There is seen a very small, approximately 4.0 mms diameter sized well-defined, hypointense lesion on the T1 Weighted images on the surface of the anterior pituitary gland, to the left of the midline, close to the cavernous segment of the left internal carotid artery. This lesion appears hyperintense on the T2 Weighted images (scans 104.7-8 & 105.7-8). Minimal superior convexity of the anterior pituitary gland is noted at that level.




After administration of contrast, on the early post-contrast images, there is rim-enhancement of the above described lesion (scan 106.6) on the delayed post-contrast images, the lesion fills up with contrast (scan 110.6).

The posterior pituitary gland reveals normal hyperintense signal on the T1 Weighted images. The pituitary stalk is in the midline. The hypothalamus is unremarkable.

The cavernous sinuses and the suprasellar cisterns are unremarkable.

No abnormality is detected in the brain parenchyma. The ventricular system is unremarkable. There is no midline shift.

Inflammatory changes are noted in the sphenoid sinus on the left.

A septum is also noted in the sphenoid sinus.

IMPRESSION :

A very small, approximately 4.0 mms diameter sized well-defined lesion on the surface of the anterior pituitary gland, to the left of the midline, close to the cavernous segment of the left internal carotid artery follows the enhancing pattern of a pituitary microadenoma.

The possibility of a Rathkes cleft cyst seems less likely.

Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O craniotomy done on 00.00.00 with excision of meningioma.
No complaints at present.
For follow up.

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 is evidence of left fronto-parietal craniotomy.

There is seen an approximately 1.1 x 1.5 cms sized intermediate signal intensity, extra-axial lesion on the T1 Weighted images in the left high parietal, parafalcine region (at the vertex) close to the superior sagittal sinus. This lesion appears relatively hypointense on the proton and T2 Weighted images (scans 104.19, 103.19, 105.8, 101.8). The lumen of the superior sagittal sinus
is not well-identified in this region.

There is predominantly hypointense signal on the T1 Weighted
images in the left fronto-parietal parafalcine cortex. This lesion appears hyperintense on the proton, T2 Weighted and FLAIR images. Focal hyperintense signal on the T1 Weighted images within this lesion represents extracellular methaemoglobin (subacute blood). Prominent sulcal space is noted in the left frontal region.

..2/.







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. No obvious vascular anomaly is identified on this study.

Incidentally noted is an empty sella.

IMPRESSION :

1. Post-operative status.

2. Altered signal in the left fronto-parietal parafalcine cortex may the sequelae of previous surgery.

3. An approximately 1.1 x 1.5 cms sized extra-axial lesion in the left high parietal, parafalcine region (at the vertex) close to the superior sagittal sinus as described may either represent surgical hemostatic material or may represent residual tumor nodule.

As compared to the previous MRI dated 00.00.00 (study no.00003), the patient is now status post-operative with near complete excision of the meningioma. ? Residual surgical hemostatic material, ?? tumor nodule is identified as described above.

A contrast enhanced scan/follow up scan would be worthwhile.
