Name of the Patient : Abc Xyzdali H. Telmn / M / 74 yrs.
Referred by : Dr. Abc Xyzhta.
Examination : Intracranial M.R.A.
CLINICAL PROFILE :
H/O altered sensorium (on and off) and gait ataxia since 2 years.
H/O loss of bladder control since 2-3 months.
The brain was screened with 5 mm thick T2 Weighted axial images.
Intracranial was performed with 3D TOF sequence.
Diffuse areas of hyperintensity on the T2 Weighted images are seen within the periventricular white matter, corona radiata and centrum semiovale bilaterally and these are most likely ischemic in etiology.
Lacunar infarcts (iso to hyperintense to CSF) are seen within the thalamus and lentiform nuclei bilaterally.
There is mild to moderate dilatation of the third and both the lateral ventricles. There is mild prominence of the cerebral cortical sulci bilaterally.
The fourth ventricle is normal. There is no shift of the midline structures.
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.
The MRA features are suggestive of :
1. Areas of altered signal within the periventricular white matter, corona radiata and centrum semiovale bilaterally are most likely ischemic in etiology.
2. Lacunar infarcts within the thalamus and lentiform nuclei bilaterally.
3. Mild to moderate dilatation of the third and both the lateral ventricles which is disproportionate to the degree of the cerebral cortical atrophy. Normal pressure hydrocephalus should be excluded.
No significant abnormality is detected on the intracranial MRA on this study.
