Name of the Patient : Abc XyzJalmn / M / 36 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O diplopia on looking left with sudden onset of giddiness and gait ataxia since 2 days.

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.

3 mm thick T1 Weighted and STIR coronal 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.

The optic nerves, visualized orbits and cavernous sinuses on either side are unremarkable.

Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.

Polyps are seen within the right maxillary sinus and sphenoid sinus on the left side.

INTRACRANIAL MRA :

The right vertebral artery is not well-visualized.

The predominant supply of both posterior cerebral arteries appears to be from the posterior communicating arteries.

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

NECK MRA :

The calibre of the right vertebral artery is smaller as compared to the left side and is most likely 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 :

The MRI/MRA features are suggestive of :

1. Smaller calibre of the right vertebral artery is most likely hypoplastic. The intracranial component is not well-visualized.

2. Polyps within the right maxillary sinus and sphenoid sinus on the left side.
