Name of the Patient : Abc Xyzrao Khailmn / M / 38 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O deviation of the left eyeball.
H/O similar complaints on the left side in 0000. Recovered with steroids.
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 and STIR coronal images through the optic nerves.
There is no focal area of altered signal intensity in the brain parenchyma.
There is an intermediate signal intensity lesion on the T1 Weighted images in the region of the left cavernous sinus and just anterior to it, which turns heterogeneously hyperintense on the STIR images.
Both the lateral and third ventricles are normal. There is mild dilatation of the fourth ventricle with slight prominence of 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 visualized optic nerves appear normal in course and signal characteristics on the STIR images.
1. Altered signal in the left cavernous sinus, extending slightly anteriorly, is not specific for a single etiology. This may represent an inflammatory lesion (? pseudotumor).
2. Mild dilatation of the fourth ventricle with slightly prominent cerebellar folia bilaterally.
A contrast enhanced scan would be worthwhile.
