Name of the Patient : Abc Xyzr Guhaghalmn / M / 60 yrs.
Referred by : Dr. Abc Xyzisheri.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O headaches since 2-3 days.
Also C/O dysphagia with giddiness and gait imbalance since 2 days.
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.
FEW IMAGES SHOW PATIENT MOTION.
There is evidence of an area of hypointensity on the T1 Weighted images which turns hyperintense on the proton, T2 Weighted and FLAIR images within the right postero-lateral aspect of the medulla. This is most likely ischemic in etiology (scans 106.3, 103.4, 107.9) The right and left vertebral arteries show normal flow void signal.
A well-defined area which is iso to hyperintense to CSF on all the pulse sequences is seen within the pons. Adjacent to this are areas of hyperintensity on the proton, T2 Weighted and FLAIR images and which would represent gliotic changes. This lesion would represent a lacunar infarct. Smaller lacunar infarcts are seen within the lentiform nuclei bilaterally.
There is mild prominence of the cerebral cortical sulci and cerebellar folia bilaterally.
Both the lateral, 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.
Also noted is an empty sella.
The MRI features are suggestive of :
1. An area of altered signal intensity within the right postero-lateral aspect of the medulla. This is most likely ischemic in etiology.
2. Lacunar infarcts within the pons and both lentiform nuclei.
