Name of the Patient : Abc Xyzaben lmn / F / 59 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O 2 episodes of seizures since 1 1/2 months.
Known hypertensive.

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 FLAIR coronal images.

5 mm thick T1 Weighted sagittal images.

After administration of contrast the following parameters were used :

5 mm thick T1 Weighted axial and 4 mm thick T1 Weighted coronal images with magnetization transfer.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is seen a fairly large, approximately 4.0 x 4.5 x 3.7 cms sized well-marginated extra-axial mass lesion overlying the right high frontal convexity, with its broad base towards the meninges. This lesion is iso to slightly hyperintense to normal white matter on the T1 Weighted images and appears heterogeneously hyperintense on the proton, T2 Weighted and FLAIR images. There is perilesional edema in the underlying brain parenchyma. A cystic/necrotic focus is noted along the posterior margin of the lesion. A CSF cleft is also noted around the lesion. Flow void signal at the periphery of the lesion on all the pulse sequences would represent blood vessels.

There is mild indentation and inferior displacement of the frontal horn and body of the right lateral ventricle. Sulcal space effacement is noted in the right frontal region with mild bulge of the anterior falx to the left.

There is mild fullness of both the lateral ventricles. The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable.

After administration of contrast there is intense enhancement of the lesion in the right frontal region (the cystic/necrotic area does not enhance). Enhancement of the meninges overlying the mass lesion is also noted.

IMPRESSION :

An approximately 4.0 x 4.5 x 3.7 cms sized well-marginated, uniformly enhancing (except for the cystic area) extra-axial mass lesion overlying the right high frontal convexity follows the signal characteristics of a meningioma.
