Name of the Patient : Abc Xyz Sinlmn / F / 49 yrs.
Referred by : Dr. Abc Xyzmpat / Dr. Abc Xyzdar.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O craniotomy done on 00.00.00 with excision of meningioma.
No complaints at present.
For follow up.
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.
5 mm thick T1 Weighted sagittal images.
There is evidence of left fronto-parietal craniotomy.
There is seen an approximately 1.1 x 1.5 cms sized intermediate signal intensity, extra-axial lesion on the T1 Weighted images in the left high parietal, parafalcine region (at the vertex) close to the superior sagittal sinus. This lesion appears relatively hypointense on the proton and T2 Weighted images (scans 104.19, 103.19, 105.8, 101.8). The lumen of the superior sagittal sinus
is not well-identified in this region.
There is predominantly hypointense signal on the T1 Weighted
images in the left fronto-parietal parafalcine cortex. This lesion appears hyperintense on the proton, T2 Weighted and FLAIR images. Focal hyperintense signal on the T1 Weighted images within this lesion represents extracellular methaemoglobin (subacute blood). Prominent sulcal space is noted in the left frontal region.
There is mild fullness of both the lateral ventricles. The 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.
Incidentally noted is an empty sella.
1. Post-operative status.
2. Altered signal in the left fronto-parietal parafalcine cortex may the sequelae of previous surgery.
3. An approximately 1.1 x 1.5 cms sized extra-axial lesion in the left high parietal, parafalcine region (at the vertex) close to the superior sagittal sinus as described may either represent surgical hemostatic material or may represent residual tumor nodule.
As compared to the previous MRI dated 00.00.00 (study no.00003), the patient is now status post-operative with near complete excision of the meningioma. ? Residual surgical hemostatic material, ?? tumor nodule is identified as described above.
A contrast enhanced scan/follow up scan would be worthwhile.
