Name of the Patient : Abc XyzV. Shlmn / M / 22 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain and
Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O giddiness.
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 GRASS coronal images.
5 mm thick T1 Weighted sagittal images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
OBSERVATION :
BRAIN :
Areas of hypointensity on the T1 Weighted images which turn hyperintense on the proton, T2 Weighted and FLAIR images are seen within the right cerebellar hemisphere, pons, left occipital lobe and right thalamus. The pons and cerebellar hemispheres are swollen and the aforementioned lesions would most likely represent recent areas of ischemia/infarction.
A small speck of hyperintensity on the T1 Weighted images within the lesion in the right cerebellar hemisphere may represent blood.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
..2/.
- 2 - Scan-00001
Inflammatory changes are seen within the sphenoid sinus and left maxillary sinus.
INTRACRANIAL MRA :
The basilar artery does not show normal flow signal and is not
visualized on the reconstructed MRA images. The posterior cerebral arteries are faintly visualized and appear to be receiving their flow from the anterior circulation.
There is slight flow signal attenuation in the right vertebral artery.
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral and left vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
NECK MRA :
The midportion of the right internal carotid artery is not well-visualized and is most likely the result of artifacts due to the intubation tubes.
The right vertebral artery is slightly hypoplastic.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
IMPRESSION :
1. Areas of altered signal within the right cerebellar hemisphere, pons, left occipital lobe and right thalamus most likely represent recent areas of ischemia/infarction. A small haemorrhagic component is seen in the right cerebral hemisphere.
2. Non-visualization of the basilar artery (? thrombus) with very faint visualization of both posterior cerebral arteries.
