Name of the Patient : Abc Xyzhai Bhadlmn / M / 62 yrs.
Referred by : Dr. Abc Xyzagwati.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O seizures since 0000.
Previous CT Scan s/o left parietal hypodense lesion. Being treated for tuberculoma since last 2 months.
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 coronal 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.
There is an ill-defined hypointense lesion on the T1 Weighted images in the left parafalcine fronto-parieto-occipital region. This is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images. A smaller circular area seen within this lesion which is seen to follow CSF characteristics on all pulse sequences represents an area of necrosis. There is thickening of the gyri in this region with involvement of the subcortical white matter. Slight thickening of the gyri is also noted in the right frontal parafalcine region (scan 104.16). There is mass effect with effacement of the adjacent sulci and compression and inferior displacement of the body and the splenium of the corpus callosum and the left lateral ventricle. There is also suspicion of involvement of part of the body of the corpus callosum.

However there is no suggestion of involvement of the body of the left lateral ventricle. There is minimal surrounding edema. Note is made of a serpingeneous flow void signal within this lesion which represent a blood vessel.
On administration of contrast, there is an ill-defined patchy enhancement in the posterior aspect of the lesion on the left side (scan 107.14).
There is a small focal hypointense area in the region of the left external capsule (scan 104.10) which is seen to follow CSF signal characteristics on all the pulse sequences and represents a lacunar infarct.
There is fullness of the ventricular system with prominence of the cerebral cortical sulci and the cerebellar folia bilaterally.
The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The MRI features are suggestive of an area of altered signal in the left parafalcine fronto-parieto-occipital region with extensions as described and most likely represents a neoplastic process like a glial cell tumor.
No previous CT Scan/investigations were available for comparison.
