Name of the Patient : Abc Xyzhchandra Tamlmn / M / 57 yrs.
Referred by : Dr. Abc Xyzlal / Dr. Abc XyzBR> Examination : Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O giddiness with gait imbalance and tremors in BUE since 4-5 months.

EXAMINATION :

The brain was screened with 5 mm thick T2 Weighted coronal images.

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

OBSERVATION :

There is a linear hyperintense signal on the T2 Weighted images in the subcortical white matter in the right posterior parietal region. This lesion most likely represents an ischemic lesion.

There is mild fullness of the third and both the lateral ventricles. The fourth ventricle is normal. There is prominence of the Sylvian fissures, cerebral cortical sulci and cerebellar folia bilaterally. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.

Inflammatory changes are noted in the left maxillary antrum.

INTRACRANIAL MRA :

There is slight ectasia of the vertebro-basilar system. The right posterior cerebral artery is seen to arise from the right internal carotid artery (continuation of the right posterior communicating artery).



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

NECK MRA :

A slight filling defect is seen along the posterior wall of the distal right common carotid artery just prior to its bifurcation. This most likely represent an atheromatous plaque.

The left common carotid artery and the internal carotid and vertebral arteries in the neck appear normal.

IMPRESSION :

1. Altered signal in the subcortical white matter in the right posterior parietal region most likely represents an ischemic lesion.

2. Mild cerebral cortical and cerebellar atrophy.

3. A small atheromatous plaque along the posterior wall of the distal right common carotid artery just prior to its bifurcation.

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