Name of the Patient : Abc Xyzra lmn / M / 46 yrs.
Referred by : Dr. Abc Xyzlkaka.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
H/O unexplained fall with head injury.
The brain was screened with 5 mm thick T2 Weighted axial 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
There is hypoplasia of the inferior cerebellar vermis. Also seen is fullness of the fourth ventricle.
Both the lateral and the third ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
Inflammatory changes are noted within the right maxillary sinus, ethmoidal air cells and sphenoid sinus.
INTRACRANIAL MRA :
The calibre of the supraclinoid segment of the left internal carotid artery is slightly less as compared to the opposite side.
The petrous and cavernous segments of the left internal carotid artery and the petrous, cavernous and supraclinoid segments of the right internal carotid artery 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 :
The left vertebral artery appears to be arising from the aortic arch.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
The MRA features are suggestive of :
1. Slightly smaller calibre of the supraclinoid segment of the left internal carotid artery (? normal variant).
2. The left vertebral artery is seen to arise from the aortic arch.
