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

CLINICAL PROFILE :

C/O seizures.

EXAMINATION :

M.R.I of the brain was performed using the following parameters :

5 mm thick T1 Weighted, proton density and T2 Weighted axial images.

5 mm thick FLAIR and 7 mm thick Fast Scan (T2 *) coronal images.

MR Cisternogram was obtained in the sagittal plane.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is evidence of a well-defined, extra-axial mass lesion in the left frontal region and which measures approximately 4.7 x 2.8 x 1.8 cms. This lesion is iso to hypointense to the gray matter on the T1 Weighted images, heterogeneously hyperintense on the proton and FLAIR images and hypointense on the T2 Weighted images. Few punctate flow void areas are noted adjacent to this lesion and would most likely represent pial vessels. Few hypointense areas at the periphery of this lesion on the T1 Weighted images which bloom on the Fast Scan (T2 *) images would represent calcification/paramagnetic substance deposition. There is compression upon the underlying brain parenchyma with buckling of the grey-white matter function.




Small bright foci on the proton, T2 Weighted and FLAIR images are seen in the frontal deep white matter and corona radiata bilaterally. These are iso to hypointense to normal white matter on the T1 Weighted images and are probably ischemic in etiology.

Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.

2D Phase contrast images were obtained for the dural venous sinuses. The superior sagittal sinus is unremarkable and is not invaded by the lesion.

Incidental note is made of bilateral mastoiditis.

IMPRESSION :

The MRI features are suggestive of :

1. A well-defined, extra-axial mass lesion in the left frontal region which measures approximately 4.7 x 2.8 x 1.8 cms and most likely represents a meningioma.

2. Areas of altered signal in the frontal deep white matter and corona radiata bilaterally are probably ischemic in etiology.
