Name of the Patient : Abc Xyz lmn / F / 40 yrs.
Referred by : Dr. Abc Xyzmpat / Dr. Abc Xyzhah.
Examination : M.R.I. of the Brain and Intracranial M.R.A.

CLINICAL PROFILE :

C/O headaches with vomiting since 1 day.
Known diabetic.

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 FLAIR sagittal images.

5 mm thick T1 Weighted sagittal images.

Intracranial MRA was performed with a 3D TOF sequence.

OBSERVATION :

BRAIN :

There are hyperintense areas on the FLAIR images within the quadrigeminal cistern, superior cerebellar cistern and few of the sulci in the parietal lobes bilaterally.

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

Both the lateral, third and the fourth ventricles are normal. There is no shift of the midline structures.
Scan-00006



INTRACRANIAL MRA :

There are small, well-circumscribed (approximately 2-3 mms in diameter) lesions in the region of the tip of the basilar artery and the distal aspect of the left posterior cerebral artery. These may represent small aneurysms.

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

IMPRESSION :

The MRI/MRA features are suggestive of :

1. Areas of altered signal intensity within the quadrigeminal cistern, superior cerebellar cistern and few of the sulci in the parietal lobes bilaterally and may represent subarachnoid hemorrhage.

2. Probable aneurysms in the region of the tip of the basilar artery and the distal aspect of the left posterior cerebral artery.

A DSA would be worthwhile.
