Name of the Patient : Abc Xyzra lmn / M / 63 yrs.
Referred by : Dr. Abc Xyznchal.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O episodic headaches with loss of vision and giddiness for 10-15 minutes (once in 15 days) since 5 years.
Known hypertensive. On Rx.

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 FLAIR coronal images.

5 mm thick T1 Weighted sagittal images.

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

OBSERVATION :

BRAIN :

There is no focal area of altered signal intensity within the brain parenchyma.

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 pansinusitis.

INTRACRANIAL MRA :

The left vertebral artery is hypoplastic.

- 2 - scan-00009/51


The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, right vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. The posterior cerebral arteries appear to be predominantly supplied by the posterior communicating arteries. No obvious aneurysm or vascular malformation is identified.

NECK MRA :

The left vertebral artery in the neck also appears hypoplastic.

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

IMPRESSION :

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