Name of the Patient : Abc Xyz lmn / F / 53 yrs.
Referred by : Dr. Abc Xyzootra.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O headaches since 15 days.
Known hypertensive/diabetic. On Rx.
The brain was screened with 5 mm thick T2 Weighted axial images and 5 mm thick FLAIR coronal images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
There is a hyperintense area in the right high posterior parietal region involving the cortex and the subcortical white matter on the T2 Weighted and FLAIR images. This is isointense to hypointense to white matter on the T1 Weighted images and are suggestive of areas of ischemia/infarction.
The internal carotid artery in the cavernous portion on the right side does not show its normal flow void signal on all the pulse sequences.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
Incidental note is made of maxillary sinusitis and inflammatory changes in the ethmoidal air cells and sphenoid sinuses.

INTRACRANIAL MRA :
The internal carotid artery on the right side in its entire intracranial portion is not visualized.
There is mild narrowing of the distal portion of the P2 segment of the right posterior cerebral artery.
The petrous, cavernous and supraclinoid segments of the left internal carotid artery shows normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, vertebral and the left 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 shows a very faint signal in the proximal portion just after its bifurcation and is then not visualized in the entire neck portion.
The left internal carotid artery is unremarkable.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no other vessel wall irregularities or stenosis of the vessels noted.
1. Areas of ischemia/infarction in the right high posterior parietal region.
2. Non-visualization of the internal carotid artery on the right side.
3. Mild narrowing of the distal portion of the P2 segment of the right posterior cerebral artery.
