Name of the Patient : Abc Xyzshna D. lmn / M / 56 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain and
Intracranial M.R.A.

CLINICAL PROFILE :

C/O giddiness, gait ataxia and speech disturbance since 3 days.
Known hypertensive and tobacco chewer.

EXAMINATION :

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

5 mm thick T1 Weighted and T2 Weighted axial images.

5 mm thick FLAIR coronal images.

Intracranial MRA was performed with 3D TOF sequence.

The neck MRA could not be performed as the patient was moving.

OBSERVATION :

BRAIN :

There are ill-defined, hyperintense areas on the T2 Weighted and FLAIR images in the thalami, bilaterally extending into the midbrain on either side and in the head of right caudate nucleus. These lesions appear iso to hypointense to normal white matter on the T1 Weighted images.

There is mild dilatation of the lateral and third ventricles. The fourth ventricle is normal.

There is slight prominence of the cerebral cortical sulci bilaterally. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.


Mucosal thickening is noted in the ethmoidal air cells bilaterally.

INTRACRANIAL MRA :

Apparent narrowing of the M1 segment of the right middle cerebral artery in its mid segment is artifactual. Motion artifacts are noted in some images.

The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, left middle cerebral, basilar, vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.

IMPRESSION :

Altered signal in the thalami, bilaterally and in the head of the right caudate nucleus most likely represents ischemic changes.

No significant abnormality is detected on the intracranial MRA on this study.
