Name of the Patient : Abc Xyz Sinlmn / F / 49 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O giddiness (on & off) since 3 months with gait ataxia on the right side 8 days back for a day.
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.
An MR Cisternogram was obtained in the coronal plane.
There is seen a fairly large, approximately 5.0 x 6.6 x 4.8 cms sized well-defined, extra-axial mass lesion in the left fronto-parietal parafalcine region. This lesion is of intermediate signal on the T1 Weighted images and is relatively hypointense on the T2 Weighted images. Few cystic areas are noted within this lesion. There is perilesional edema in the underlying brain parenchyma with sulcal space effacement, midline shift to the right and inferior displacement and slight effacement of the lateral ventricles bilaterally. A CSF cleft is noted around this lesion. Multiple linear signal-void lesions around the above described mass lesion represents blood vessels.
This lesion has its broad base towards the dural surface. The superior sagittal sinus in its midsegment is most probably compressed by the lesion. There is however no evidence of definite invasion of the superior sagittal sinus by the mass lesion.
The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. No obvious vascular anomaly is identified on this study.
An approximately 5.0 x 6.6 x 4.8 cms sized well-defined, extra-axial mass lesion in the left fronto-parietal parafalcine region with signal characteristics and extensions as described most likely represents a meningioma.
