Name of the Patient : Abc Xlmn / F / 57 yrs.
Referred by : Dr. Abc Xyzrdiwalla.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O right sided headaches with burning sensations and giddiness.
Also C/O tinnitus on both sides (right more than left) with decreased hearing.
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 and Fast Scan (T2 *)_coronal images.
5 mm thick T1 Weighted sagittal images.
There are ill-defined, hyperintense areas on the proton, T2 Weighted and FLAIR images in the frontal, parietal and temporal white matter bilaterally. These areas appear hypointense to normal white matter on the T1 Weighted images.
Flame-shaped, hypointense areas on the T1 Weighted images are noted in the posterior parietal deep white matter bilaterally (scans 104.13/14). These areas follow CSF signal on all the pulse sequences and may represent either prominent perivascular spaces or may represent the sequelae of a previous demyelinating lesion/ischemic lesion.
Prominent perivascular spaces are noted in the cerebral hemispheres bilaterally.
Mild fullness of the both the lateral ventricles is noted. The third and the fourth ventricles are normal. There is slight prominence of the cerebral cortical sulci and cerebellar folia bilaterally. 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. Altered signal in the frontal, parietal and temporal white matter bilaterally is not specific for a single etiology. These lesions may either represent ischemic lesions or demyelinating lesions.
2. Flame-shaped, CSF signal intensity lesions in the posterior parietal deep white matter bilaterally may represent either prominent perivascular spaces or may represent the sequelae of a previous demyelinating lesion/ischemic lesion.
