Name of the Patient : Abc Xyz Sanlmn / M / 46 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O headaches and long standing giddiness.
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.
There is no focal area of altered signal intensity within the brain parenchyma.
There is mild fullness of the third and both the lateral ventricles. There is mild prominence of the cerebral cortical sulci bilaterally.
The fourth ventricle is normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
Note is made of a right maxillary polyp. Inflammatory changes are noted in the frontal sinuses and ethmoidal air cells.
INTRACRANIAL MRA :
The left vertebral artery and the A1 segement of the right anterior cerebral artery are hypoplastic.
There is ectasia of the vertebral arteries.
The right posterior cerebral artery appears to be a continuation of the right posterior communicating artery.
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized left anterior cerebral, middle cerebral, basilar, right vertebral and left posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
NECK MRA :
The left vertebral artery in the neck is also hypoplastic.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
The MRI/MRA features are suggestive of a hypoplastic left vertebral artery and the A1 segment of the right anterior cerebral artery.
No other significant abnormality is detected on this study.
