Name of the Patient : Abc Xyzen Marlmn / F / 68 yrs.
Referred by : Dr. Abc Xyzhah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O headaches with 1 episode of vomiting since 7.00 am of 00.00.00.

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 and Fast Scan (T2 *) coronal images.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is an intermediate signal intensity lesion on the T1 Weighted images in the prepontine, suprasellar and the quadrigeminal cisterns. This is seen to hyperintense on the proton, T2 Weighted and FLAIR images. Similar altered signal is also noted in the frontal temporal sulcal spaces and Sylvian fissures bilaterally with effacement of the sulci. This would represent subarachnoid haemorrhage.

There is slight fullness of both the lateral ventricles. The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. The vertebro-basilar system is ectatic. Blooming on the Fast Scan (T2 *) images is seen in the globus pallidi and this would represent calcification/deposition of paramagnetic substances.

Incidental note is made of bilateral maxillary polyps.

IMPRESSION :

The MRI findings are suggestive of altered signal intensity areas within the basal cisterns as described and this most likely represents subarachnoid haemorrhage.

An MR angiograph/DSA would be worthwhile.
