Name of the Patient : Abc Xyznisa Huslmn / F / 70 yrs.
Referred by : Dr. Abc Xyzidhungat.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O seizures and vomiting.
Alleged H/O head injury.
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 evidence of a fairly well-defined extra-axial mass lesion in the right frontal region, measuring approximately 1.3 x 1.1 x 1.3 cms. This lesion is near isointense to gray matter on the T1 Weighted images and turns hypointense on the T2 Weighted images. It is seen to indent the right frontal lobe. The underlying brain parenchyma shows a hyperintense signal on the proton, T2 Weighted and FLAIR images, which may represent perilesional edema.
Diffuse, irregularly defined areas of hyperintensity on the proton, T2 Weighted and FLAIR images are seen within the periventricular white matter, corona radiata and centrum semiovale bilaterally. These are isointense to hypointense to normal white matter on the T1 Weighted images and are most likely ischemic in etiology. Smaller areas with similar signal characteristics are evident within the lentiform nuclei bilaterally and right thalamus.
There is a lacunar infarct (isointense to hyperintense to CSF) within the head of the right caudate nucleus.
There is slight fullness of the third and both the lateral ventricles. Note is made of an empty sella. There is prominence of the cerebral cortical sulci bilaterally. Also seen is mild prominence of the basal cisternal spaces and cerebellar folia bilaterally.
An air-fluid level is noted within the right maxillary sinus (? inflammatory changes, ? blood).
The fourth ventricle is normal. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The cervical spine was screened with 4 mm thick T2 Weighted sagittal images and shows degenerative changes.
The MRI features are suggestive of :
1. An extra-axial mass lesion measuring approximately 1.3 x 1.1 x 1.3 cms in the right frontal region. This most likely represents a meningioma.
2. Areas of altered signal intensity within the periventricular white matter, corona radiata, centrum semiovale, and in the lentiform nuclei bilaterally and right thalamus are most likely ischemic in etiology
3. A lacunar infarct in the head of the right caudate nucleus.
