Name of the Patient : Abc Xyzhchandra lmn / M / 28 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Cervical Spine.

CLINICAL PROFILE :

C/O paresthesias in BLE.

EXAMINATION :

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

4 mm thick T1 Weighted and T2 Weighted sagittal images.

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

OBSERVATION :

The cervical intervertebral discs show slight loss of water content.

Small posterior disc bulges are noted at the C3-C4, C4-C5, C5-C6 and C6-C7 levels.

Slight facetal hypertrophy is noted at the C2-C3, C3-C4, C4-C5 and C5-C6 levels.

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 atlanto-axial region and the cervico-medullary junction are unremarkable.
Scan-00007

The dorsal spine was screened with 4 mm thick T2 Weighted sagittal images and 5 mm thick T1 Weighted axial images. There is seen an approximately 2.8 x 1.5 x 9.9 cms sized extramedullary lesion posterior to the spinal cord extending over the D6-D7 disc level upto the D11 vertebral level. This lesion follows CSF signal characteristics on all the pulse sequences and extends into the neural foramen along the nerve roots over these levels. This lesion most likely represents an arachnoid cyst (? neuroenteric cyst). There is resultant significant compression and thinning of the dorsal spinal cord over the D7 to D10 vertebral levels. It is difficult to assess the signal characteristics of the cord over these levels in view of the significant thinning of the cord. Slight widening of the spinal canal over the affected levels is noted.

Small postero-central disc herniations with peridiscal osteophytes at the D7-D8, D8-D9 and D9-D10 levels.

IMPRESSION :

1. Small posterior disc bulges at the C3-C4, C4-C5 and C5-C6 and C6-C7 levels.

2. Slight facetal hypertrophy at the C2-C3, C3-C4, C4-C5 and C5-C6 levels.

3. An approximately 2.8 x 1.5 x 9.9 cms sized extramedullary lesion posterior to the spinal cord extending over the D6-D7 disc level upto the D11 vertebral level most likely represents an arachnoid cyst. There is resultant cord compression and thinning of the dorsal spinal cord over the extent of the lesion.

A dedicated study of the dorsal spine would be worthwhile.
