Name of the Patient : Abc Xyz lmn / M / 51 yrs.
Referred by : Dr. Abc Xyzrikh.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O closure of the right eye with right sided headaches.
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.
3 mm thick T1 Weighted coronal 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.
There is no focal area of altered signal intensity within the brain parenchyma.
There is an intermediate signal intensity lesion on the T1 Weighted images in the
interhemispheric fissure in the high frontal region, which appears relatively hypointense on the T2 Weighted images.
There is mild fullness of both the lateral ventricles. The third and the fourth ventricles are normal.
The cerebellar hemisphers are slightly hypoplastic with a mega cisterna magna. The rest of the
basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
There is still seen an intermediate signal intensity lesion on the T1 Weighted images in the right cavernous sinus. This lesion appears relatively hypointense on the T2 Weighted images. The cavernous segment of the right internal carotid artery is partially encased by the lesion but shows normal flow-void signal. The left cavernous sinus, sella and suprasellar cistern are unremarkable.

The visualized orbtis and orbital apices are unremarkable. The visualized optic nerves show normal signal intensity.
Mucosal thickening is noted in the maxillary sinus and ethmoidal air cells on the right side.
Inflammatory changs are noted in the mastoid air cells bilaterally.
Marrow of the clivus is slightly inhomogeneous.
After contrast administration, there is patchy enhancement of the lesion in the right cavernous sinus. Intense enhancement of the lesion in the interhemispheric fissure in the high frontal region is also noted.
1. No abnormality is detected in the brain parenchyma per se.
2. Patchy enhancing lesion in the right cavernous sinus as described.
3. Enhancing lesion in the interhemispheric fissure in the high frontal region may also represent an inflammatory meningeal lesion.
As compared to the previous MRI (scan nos. 00006/45) dated 29/00.00.00, there appears to be slight reduction in the bulk of the lesion in the right cavernous sinus and interhemispheric
