Name of the Patient : Abc Xyz Almn / M / 38 yrs.
Referred by : Dr. Abc Xyznghal.
Examination : Intracranial and Neck M.R.A.

CLINICAL PROFILE :

C/O headaches, giddiness and nausea.

EXAMINATION :

The brain was screened with 5 mm thick FLAIR axial and T1 Weighted sagittal images.

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

OBSERVATION :

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

Note is made of an empty sella.

Both the lateral, third and the fourth ventricles are normal. There is no shift of the midline structures.

Mucosal thickening is seen in both the maxillary sinuses.

INTRACRANIAL MRA :

There is a well-circumscribed area in contiguity with the mid-aspect of the M1 segment of the left middle cerebral artery, superiorly (in the region of the origin of the M2 segment of the left middle cerebral artery).

The overall calibre of the internal and common carotid arteries and the vertebral artery on the right is smaller as compared to the opposite side.

There is flattening of the carotid bulb on the right side. Flow related artifacts are noted at the common carotid artery bifurcations bilaterally.

The petrous, cavernous and supraclinoid segments of the left internal carotid artery shows normal signal and calibre. The visualized anterior cerebral, right middle cerebral, basilar, left vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins.

IMPRESSION :

The MRA features are suggestive of :

1. An area of altered signal along the mid-aspect of the M1 segment of the left middle cerebral artery, superiorly (in the region of the origin of the M2 segment of the left middle cerebral artery). This may represents an aneurysm
and a DSA may be worthwhile.

2. Overall smaller calibre of the internal and common carotid arteries and the vertebral artery on the right as compared to the opposite side.

3. Flattening of the carotid bulb on the right side.
