Name of the Patient : Abc Xyz. Pallmn / F / 40 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O left sided headaches with drooping of the left eyelid and diplopia since 15 days.
Similar history 1 year ago from which patient recovered.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick T1 Weighted and STIR coronal images.
After administration of contrast the following parameters were used :
3 mm thick T1 Weighted coronal and axial images with fat saturation.
5 mm thick T1 Weighted axial and coronal images.
There is an intermediate signal intensity lesion in the left cavernous sinus extending slightly anterior to the superior orbital fissure (se/im:105/6,7, 106/7,8 & 107/7,8) on the T1 Weighted images. This is seen to turn heterogeneously hyperintense on the STIR images. On administration of contrast, there is enhancement of this lesion.
There is no focal area of altered signal intensity in the brain parenchyma.
Both the lateral, third and the fourth ventricles are normal. 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 no area of abnormal enhancement within the brain parenchyma or along the meninges.
Incidental note is made of mild bilateral maxillary sinusitis.
The MRI features are suggestive of altered signal in the left cavernous sinus extending slightly anterior to the superior orbital fissure with enhancement as described and is most probably due to an inflammatory process like a pseudotumor (in view of the similar past history).
The possibility of a neoplastic lesion seems less likely.
