Name of the Patient : Abc Xyz Mlmn / F / 10 yrs.
Referred by : Dr. Abc Xyzla.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O headaches, vomiting and convulsions 10 days back.
H/O similar episode 1 year ago.

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 and coronal images.

OBSERVATION :

There is evidence of a fairly well-defined, extra-axial mass lesion in the right fronto-temporo-parietal regions and measuring approximately 8.0 x 7.0 x 4.8 cms.

This lesion is iso to hypointense to gray matter on all the pulse sequences. A few hypointense areas on the T1 Weighted images which turn hyperintense on the proton and T2 Weighted images are seen within the lesion and may represent cystic/necrotic changes. Few hypointense areas on all the pulse sequences are seen within this lesion and may represent calcium. A CSF cleft is seen around this lesion with a presence of curvilinear and punctate signal voids suggestive of pial vessels. There appears to be hyperostosis of the bone adjacent to the lesion.

This lesion is seen to compress upon the adjacent brain parenchyma and the third and both the lateral ventricles. Also seen is right uncal herniation and effacement of the right perimesencephalic cistern with compression upon the midbrain and aqueduct. Also seen is compression and displacement of the right middle cerebral artery.
..2/.







There is dilatation of the left lateral ventricle with periventricular hyperintensities on the proton, T2 Weighted and FLAIR images suggestive of CSF ooze.

Note is made of an empty sella.

The fourth ventricle is normal.

IMPRESSION :

The MRI features are suggestive of an extra-axial mass lesion in the right fronto-temporo-parietal regions and measuring approximately 8.0 x 7.0 x 4.8 cms with mass effect as described and most likely represents a meningioma.
