Name of the Patient : Abc Xyzhaturlmn / F / 65 yrs.
Referred by : Dr. Abc Xyz Sampat.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O progressive dementia with right focal findings (? multi-infarct dementia).

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.

FEW IMAGES SHOW PATIENT MOTION INSPITE OF SEDATION.

OBSERVATION :

Areas of hypointensity on the T1 Weighted images which turn hyperintense on the proton, T2 Weighted and FLAIR images are noted within the pons, periventricular white matter and corona radiata bilaterally.

Fairly well-defined areas which are iso to hyperintense to CSF on all the pulse sequences (lacunar infarcts) are seen within the lentiform nuclei, thalamus and corona radiata bilaterally.

There is mild fullness of the ventricular system and prominence of the basal cisternal spaces, cerebral cortical sulci and cerebellar folia bilaterally.

A CSF intensity lesion is seen lateral to the left cerebellar hemisphere (with indentation upon it) which may represent an arachnoid cyst). Note is made of an empty sella.

The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

IMPRESSION :

The MRI features are suggestive of :

1. Areas of altered signal within the pons, periventricular white matter and corona radiata bilaterally are most likely ischemic in etiology.

2. Lacunar infarcts within the lentiform nuclei, thalamus and corona radiata bilaterally.

The above findings may be seen with multi-infarct dementia.

3. A probable arachnoid cyst, lateral to the left cerebellar hemisphere.
