Name of the Patient : Abc XyzK. Kumlmn / M / 19 yrs.
Referred by : Dr. Abc Xyzdar.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O giddiness with LOC for an hour on 00.00.00.
Now C/O loss of taste.

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 and Fast Scan (T2 *) coronal images.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is a small, well-marginated hypointense lesion with a peripheral hyperintense rim on the T1 Weighted images in the right thalamus which appears hyperintense on the T2 Weighted and FLAIR images and represents a lacunar infarct (the peripheral hyperintense rim on the T1 Weighted images may represent paramagnetic substances).

Both the lateral, third and the fourth ventricles are normal. A mega cisterna magna is noted. The rest of the basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

There is occipitalization of the atlas. There is atlanto-dens subluxation with the atlanto-dens interval measuring approximately 9.0 mm. There is however no significant cord compression noted on this study.



IMPRESSION :

1. A lacunar infarct in the right thalamus.

2. Occipitalized atlas with atlanto-dens subluxation with the atlanto-dens interval measuring approximately 9.0 mm.

If clinically indicated, a dedicated study of the cervical spine would be worthwhile.

As compared to the previous MRI dated 00.00.00, there is a decrease in the size of the lesion in the right thalamus. The left thalamic lesion and lesion in the splenium of the corpus callosum on the left side is not well-appreciated on this study. Contrast was not administered during the present study.
