Name of the Patient : Abc Xyzhai Jalmn / M / 72 yrs.
Referred by : Dr. Abc Xyzh Shah / Dr. Abc Xyztrak.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O left sided hemiparesis since 8.00 am of 00.00.00 with dysarthria.
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.

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

FEW IMAGES SHOW PATIENT MOTION.

OBSERVATION :

BRAIN :

There is an ill-defined, hyperintense signal, best appreciated on the FLAIR images along the right cerebral cortex and in the right lentiform nucleus, head of the right caudate nucleus and right thalamus. This signal appears hypointense to normal grey matter on the T1 Weighted images. Resultant mild effacement of the cerebral cortical sulci in the right cerebral hemisphere is noted. The intracranial segment of the right internal carotid artery shows an intraluminal signal on all the pulse sequences.
Scan-00002


Lacunar infarcts (iso to hyperintense to CSF) are noted in the right thalamus, head of the left caudate nucleus and in the deep white matter in the left parietal region.

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

INTRACRANIAL MRA :

There is non-visualization of the intracranial segment of the right internal carotid artery and its branches (though there is very faint visualization of the proximal right middle cerebral artery).

The petrous, cavernous and supraclinoid segments of the left internal carotid artery 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.

NECK MRA :

The right internal carotid artery in the neck is also not visualized from the right common carotid bifurcation. The right external carotid, the left internal carotid artery and its bifurcation and the vertebral arteries are unremarkable.

IMPRESSION :

1. Altered signal along the cortex of the right cerebral hemisphere and in the right lentiform nucleus, head of the right caudate nucleus and right thalamus represents a recent ischemic lesion.

2. Lacunar infarcts in the right thalamus, head of the left caudate nucleus and in the deep white matter in the left high parietal region.

3. Non-visualization of the right internal carotid artery and its branches from the right common carotid bifurcation (though there is very faint visualization of the proximal
right middle cerebral artery) may suggest thrombosis of the vessel.
