Name of the Patient : Abc Xyzlal lmn / M / 78 yrs.
Referred by : Dr. Abc XyzS. Bhagvat.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O 4 episodes of weakness of BLE with fall in 4-5 years.
Known 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.
5 mm thick T1 Weighted sagittal images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
OBSERVATION :
BRAIN :
There are ill-defined, hyperintense areas in the fronto-parietal and the periventricular deep white matter on the proton, T2 Weighted and FLAIR images. These are isointense to normal white matter on the T1 Weighted images and are ischemic in etiology.
There is mild dilatation of both the lateral and the third ventricles. The fourth ventricle is normal. The basal cisternal spaces are unremarkable. There is prominence of the cerebral cortical sulci and cerebellar folia bilaterally. There is no shift of the midline structures.
Incidental note is made of right maxillary sinusitis and an empty sella.

INTRACRANIAL MRA :
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 :
There is a filling defect along the posterior wall of the right internal carotid artery just distal to its bifurcation which probably represents an atherosclerotic plaque.
The common carotid arteries, left internal carotid artery and the external carotid arteries appear normal bilaterally.
IMPRESSION :
1. Areas of altered signal in the fronto-parietal and the periventricular deep white matter are ischemic in etiology.
2. A filling defect along the posterior wall of the right internal carotid artery just distal to its bifurcation probably represents an atherosclerotic plaque.
