Name of the Patient : Abc Xyza lmn / F / 38 yrs.
Referred by : Dr. Abc Xyzve / Dr. Abc XyzVyas.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O sudden onset of fall with giddiness.

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.
4 mm thick T2 Weighted sagittal images.
3 mm thick T1 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is suggestion of occipitalization of the posterior arch of the atlas.

There is atlanto-dens subluxation with the atlanto-dens distance measuring approximately 9.0 mms. There is indentation upon the cervico-medullary junction by the postero-superior aspect of the odontoid process.

There is no focal area of altered signal intensity within the brain parenchyma.

There is slight 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.





IMPRESSION :

1. Probable occipitalization of the posterior arch of the atlas. Correlation with plain radiographs would be worthwhile.

2. Atlanto-dens subluxation with the atlanto-dens distance measuring approximately 9.0 mms with indentation upon the cervico-medullary junction by the postero-superior aspect of the odontoid process.
