Name of the Patient : Abc Xyz Shlmn / M / 76 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain and Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O momentary loss of memory since 00.00.00 and mild momentary loss of speech 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 Fast Scan (T2 *) and FLAIR coronal images.

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

OBSERVATION :

BRAIN :

There is an ill-defined, hyperintense signal on the proton, T2 Weighted and FLAIR images in the left thalamus, anteriorly. This lesion appears isointense to normal grey matter on the T1 Weighted images.

A small bright focus on the T2 Weighted and FLAIR images is noted in the posterior parietal deep white matter, which may represent an ischemic focus.

There is mild dilatation of both of the lateral and third ventricles. The fourth ventricle is normal.
There is slight prominence of the slight cerebral cortical sulci, cerebellar folia and basal cisternal spaces, bilaterally.

There is no shift of the midline structures.

There is no obvious haemorrhage on this study.

Mucosal thickening is noted in the maxillary antra, bilaterally.

INTRACRANIAL MRA :

There is ectasia of the vertebro-basilar system.

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. The anterior communicating artery on the right side is hypoplastic and may be a normal variant. No obvious aneurysm or vascular malformation is identified.

NECK MRA :

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

IMPRESSION :

1. Altered signal in the left thalamus, anteriorly and in the left posterior parietal deep white matter, may represent ischemic focus.

2. Ectatic vertebro-basilar system.

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