Name of the Patient : Abc Xyzar lmn / M / 3 yrs.
Referred by : Dr. Abc Xyzsai Hospital.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O head trauma with right frontal contusion in November 0000.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick T2 Weighted and 5 mm thick GRASS coronal images.
5 mm thick T1 Weighted sagittal images.
There are well-marginated areas of hyperintensity on all the pulse sequences within the left frontal lobe, anterior to the left frontal horn, which may represent protein material/hemoglobin breakdown products. A few areas are hypointense on the T1 Weighted images and turn hyperintense on the proton and T2 Weighted images and may represent gliotic changes. Few areas are seen to bloom on the GRASS images and may represent paramagnetic substances/hemosiderin.
Ill-defined, hyperintense areas on all pulse sequences in the left inferior frontal lobe may represent calcium (on correlating with previous CT Scan dated 00.00.0000).
Hypointense areas on the T1 Weighted images which turn hyperintense on the T2 Weighted images are seen in the left inferior frontal lobe and may represent gliosis the result of previous contusions.
Note is made of a cavum septum pellucidum and vergae.
Ill-defined, hyperintense areas on the proton and T2 Weighted images are noted in the periventricular white matter in the frontal regions 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.
The MRI features are suggestive of a heterogenous lesion involving the left frontal lobe as described. This lesion is not specific for a single etiology. This may represent a vascular malformation like a cavernous angioma with calcium and hemoglobin breakdown products. Superimposed changes of previous contusion are noted.
The possibility of a neoplasm seem less likely.
A follow-up MRI scan may be worthwhile.
