Name of the Patient : Abc Xyzi Salmn / F / 40 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O occasional headaches with giddiness.
H/O visual loss (left more than right) since 15 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.

4 mm thick T1 Weighted coronal images.

5 mm thick FLAIR coronal images.

3 mm thick STIR coronal images.

5 mm thick T1 Weighted sagittal images.

PATIENT REFUSED CONTRAST EXAMINATION.

OBSERVATION :

There is a large extra-axial mass lesion in the interhemispheric frontal region which measures approximately 3.5 x 4.2 x 4.4 cms in the largest dimension. This lesion is seen to extend posteriorly displacing the optic chiasma postero-inferiorly. There is compression upon the overlying frontal lobes bilaterally. The anterior cerebral arteries are also displaced posteriorly. A CSF cleft is seen around the lesion with pial vessels. This lesion is hypointense to white matter on the T1 Weighted images and turns heterogeneously hyperintense to the grey matter on the proton, T2 Weighted and FLAIR images. There is slight extension into the suprasellar cistern. The lesion is seen to have a broad base.


Hyperintense areas are seen in the frontal deep white matter bilaterally on the proton and T2 Weighted images suggestive of perilesional edema.

There is moderate dilatation of both the lateral and third ventricles. The fourth ventricle is normal.

IMPRESSION :

The MRI features are suggestive of an extraaxial mass lesion in the interhemispheric frontal region measuring approximately 3.5 x 4.2 x 4.4 cms and represents a meningioma.

A contrast enhanced study would be worthwhile.
