Name of the Patient : Abc Xyzn lmn / F / 73 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O right sided hemiplegia with aphasia since 00.00.00.
Known hypertensive.

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 and Fast Scan (T2 *) coronal images.

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

SOME IMAGES SHOW PATIENT MOTION.

OBSERVATION :

BRAIN :

There is still seen an ill-defined, hyperintense signal on the proton, T2 Weighted and FLAIR images along the cortex in the left fronto-parietal, parafalcine region. This lesion appears hypointense on the T1 Weighted images and most likely represents an ischemic lesion. Resultant indentation is noted on the frontal horn of the left lateral ventricle. Involvement of the left half of the corpus callosum is also noted.

Lacunar infarcts are noted in the lentiform nuclei bilaterally, left thalamus, corona radiata and left centrum semiovale.
- 2 - Scan-00004
There is mild fullness of both the lateral and third ventricles. The fourth ventricle is normal. There is slight prominence of the cerebral cortical sulci and basal cisternal spaces bilaterally. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

There is no evidence of haemorrhage on this study.
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 :

Motion artifacts are noted.

The common carotid arteries and their extracranial branches appear normal bilaterally. There are no obvious vessel wall irregularities or stenosis of the vessels noted.

IMPRESSION :

1. Altered signal along the left fronto-parietal, parafalcine cortex represents a recent ischemic insult along the distribution of the left anterior cerebral artery.

2. Lacunar infarcts in the lentiform nuclei bilaterally, left thalamus, corona radiata and left centrum semiovale.

3. No significant abnormality is detected within the brain parenchyma or on the intracranial and neck MRA on this study.

As compared to the previous MRI (study no:00000) dated 00.00.00, the previously identified ischemic lesion now seems better defined. There is no evidence of haemorrhage on the present study.
