Name of the Patient : Abc Xyzbhai Mamlmn / M / 51 yrs.
Referred by : Dr. Abc Xyzanavati.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O headaches, vomiting and dysphagia with acute onset of paresthesias.
EXAMINATION :
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.
3 mm thick T2 Weighted coronal images through the brainstem.
2D Phase contrast angiography images were also obtained.
OBSERVATION :
There is a hyperintense signal on the proton, T2 Weighted and FLAIR images in the right lateral medulla, posteriorly. This lesion appears iso to hypointense to normal white matter on the T1 Weighted images and represents a right lateral medullary infarct.
There are ill-defined hyperintense areas on the proton, T2 Weighted and FLAIR images in the posterior parietal periventricular white matter bilaterally and bilateral centrum semiovale. These lesion appear iso to hypointense to normal white matter on the T1 Weighted images and most likely represent ischemic changes.
Lacunar infarcts are noted in the left cerebellar hemisphere, head of right caudate nucleus, left posterior parietal periventricular white matter and in the left centrum semiovale.
There is mild dilatation of both the lateral and third ventricles. The fourth ventricle is normal. There is slight prominence of the cerebral cortical sulci and the basal cisternal spaces bilaterally. There is no shift of the midline structures.
The limited phase contrast angiographic images do not show any significant feature of note.
IMPRESSION :
1. A right lateral medullary infarct.
2. Altered signal in the posterior parietal periventricular white matter bilaterally and bilateral centrum semiovale most likely represent ischemic changes.
3. Lacunar infarcts in the left cerebellar hemisphere, head of right caudate nucleus, left posterior parietal periventricular white matter and in the left centrum semiovale.
