Name of the Patient : Abc Xyzkala Palmn / F / 55 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O tremors with paresthesias in the LUE since 2 years.
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.
MR cisternogram was obtained in the sagittal plane.
There is seen a fairly large, approximately 5.0 x 4.8 x 4.2 cms sized well-marginated, extra-axial mass lesion in the right high parietal region with its broad base towards the dura. This lesion follows CSF signal characteristics on all the pulse sequences and has multiple septae within. Resultant indentation of the right parietal lobe is noted with minimal inferior displacement of the posterior body of the right lateral ventricle and slight sulcal effacement in the right high parietal region. There is mild shift of the falx to the left side. There is no perilesional edema.
The left lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is slight prominence of the cerebellar folia bilaterally. No obvious vascular anomaly is identified on this study.
Inflammatory changes are noted in the sphenoid sinus on the right.
An approximately 5.0 x 4.8 x 4.2 cms sized CSF intensity, extra-axial mass lesion in the right high parietal region, most likely represents a multi-septate arachnoid cyst.
