Name of the Patient : Abc Xyz Plmn / M / 35 yrs.
Referred by : Dr. Abc Xyzandel.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
H/O fall with injury to back of the head with vomiting and LOC for 12-13 hours.
Now C/O pain in the back of the head and in both shoulders.
The brain was screened with 5 mm thick T2 Weighted axial images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
There is an ill-defined, hyperintense area in the left high frontal region on the T1 Weighted images which is seen to remain hyperintense on the T2 Weighted images and would represent extracellular methaemoglobin. There is slight effacement of the adjacent sulci and mild perilesional edema.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
Incidental note is made of left maxillary sinusitis.
INTRACRANIAL MRA :
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
- 2 - Scan-00002
NECK MRA :
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
Altered signal in the left frontal region would represent extracelluar methemoglobin suggesting a residual, late subacute hematoma.
No significant abnormality is detected on the intracranial and neck MRA on this study.
