Name of the Patient : Abc XyzHameed Slmn / M / 51 yrs.
Referred by : Dr. Abc Xyzla.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O headaches since 1 1/2 years.
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 and Fast Scan 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.
FEW IMAGES SHOW PATIENT MOTION.
OBSERVATION :
There is evidence of a well-defined, extra-axial mass lesion measuring approximately 6.3 x 5.1 x 7.1 cms in the left fronto-temporal region. This lesion is iso to hypointense to grey matter on all the pulse sequences. Few punctate/curvilinear hypointensities are seen along the rim of this lesion and they may represent pial vessels. Also seen is an adjacent CSF cleft. There is thickening of the skull vault suggestive of hyperostosis calcification is seen within the lesion better appreciated on the CT Scan. The left middle cerebral artery appears larger than the right suggesting increased vascularity. After administration of contrast, this lesion shows intense and homogeneous enhancement with presence of a dural tail.
>
This lesion is seen to compress upon the underlying left fronto-temporal lobes with presence of slight perilesional edema. There is compression upon the left lateral and the third ventricles with a resultant shift of the midline to the right side. Also seen is left uncal and transtentorial herniation with effacement of the suprasellar and perimesencephalic cistern and compression of the midbrain. There is mild dilatation of the right lateral ventricle and the fourth ventricle seems to be stretched out.
There is destruction of the adjacent left fronto-temporal bones with extension of this lesion into the subgaleal soft tissues.
Incidental note is made of pansinusitis.
IMPRESSION :
The MRI features are suggestive of an extra-axial mass lesion measuring approximately 6.3 x 5.1 x 7.1 cms in the left fronto-temporal region with mass effect as described. This most likely represents a meningioma.
The possibility of a metastatic deposit/lymphoma seems unlikely.
