Name of the Patient : Abc Xyz G. Klmn / F / 67 yrs.
Referred by : Dr. Abc Xyzaria / Dr. Abc Xyztrak.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O left sided hemiparesis on 00.00.00 from which patient recovered in 10 minutes.
Known hypertensive/diabetic.

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.

Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.

OBSERVATION :

BRAIN :

There are ill-defined, hyperintense areas on the proton, T2 Weighted and FLAIR images in the posterior parietal periventricular white matter bilaterally. These appear isointense to hypointense to normal white matter on the T1 Weighted images and most likely represents ischemic changes. Small bright foci on the proton, T2 Weighted and FLAIR images are noted in the subcortical and deep white matter in the frontal and parietal regions bilaterally and these may also represent ischemic changes.

Prominent perivascular spaces are noted in the cerebral hemispheres bilaterally.

There is mild fullness of both the lateral and the third ventricles. The fourth ventricle is normal. The basal cisternal spaces are unremarkable. There is no shift of the midline
structures.

INTRACRANIAL MRA :

The right vertebral artery and the A1 segment of the right anterior cerebral artery appear hypoplastic. The vertebro-basilar system appears ectatic.

Slight irregularity and narrowing of the M1 segment of the left middle cerebral artery in its mid-segment is noted. The Sylvian branches of the left middle cerebral artery are however well-identified.

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

NECK MRA :

The right vertebral artery in the neck also appears hypoplastic.

The common carotid arteries and their bifurcations and the left vertebral artery appear normal. There are no vessel wall irregularities or stenosis of the vessels noted.

IMPRESSION :

1. Altered signal in the posterior parietal periventricular white matter bilaterally most likely represents ischemic changes.

2. Small foci of altered signal in the subcortical and deep white matter in the frontal and parietal regions bilaterally also represent ischemic changes.

3. Hypoplastic right vertebral artery and the A1 segment of the right anterior cerebral artery.

4. Slight irregularity and narrowing of the M1 segment of the left middle cerebral artery in its mid-segment may be atherosclerotic in etiology.
