Name of the Patient : Abc Xyzo lmn / M / 36 yrs.
Referred by : Dr. Abc Xyzrani / Dr. Abc Xyzhta.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O headaches and memory impairment since 2 months.
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 T1 Weighted and 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 coronal images with magnetization transfer.
5 mm thick T1 Weighted sagittal images.
OBSERVATION :
There is a large extra-axial well-defined, mass lesion in the left temporal lobe superior to the left tentorium which measures approximately 4.0 x 3.8 x 5.1 cms. This lesion is hypointense to the gray matter on the T1 Weighted images and is heterogeneously hypointense on the proton, T2 Weighted and FLAIR images with a few hyperintense areas which may represent necrotic changes. Large dilated tortuous flow void areas which represent vessels are seen within and the periphery of the lesion. There is mass effect upon the underlying brain parenchyma with edema. There is effacement of the adjacent sulci and the left Sylvian fissure. Edema is also seen to encroach into the posterior limb of the left internal capsule and the external capsule. There is also compression upon the body of the left lateral and the third ventricle, effacement of the perimesencephalic cistern on the left side with shift of the midline structure to the right.

After contrast administration there is fairly homogeneous enhancement of the lesion.
There is mild fullness of the right lateral ventricle. The fourth ventricle is normal. The basal cisternal spaces are unremarkable.
The left transverse and the sigmoid sinus and the other venous sinuses appear normal.
IMPRESSION :
The MRI features are suggestive of a large highly vascular extra-axial lesion most likely a meningioma in the left temporal lobe measuring approximately 4.0 x 3.8 x 5.1 cms. with edema and mass effect as described.
