Left frontal hypodensity following head injury. No intracerebral hematoma in between. To r/o underlying lesion
Diagnosis
Left frontal hypodensity
Report:
Contrast MRI Brain:
Findings:
There is focal parenchymal loss in the left pre-central gyrus with widening of the sulcal space. Small area of mildly hyperintense signal in T2FLAIR sequence in the adjacent brain parenchyma can represent gliosis.
Abnormal high T2 signal lesion in the right frontal-parietal region with loss of gray-white matter differentiation. No definite contrast enhancement (except for traversing vessels). No restricted diffusion evident (T2 shine through seen in the ADC map). Features may represent gliosis from previous insult (e.g. contrecoup contusion injury pattern given the above observation of the left prefrontal parenchymal loss) in the clinical context.
No other focal parenchymal lesion in the rest of the brain.
No intracranial haemorrhage.
No hydrocephalus.
Rest of the intracranium is unremarkable
Conclusion:
1.Focal parenchymal loss in left pre-frontal gyrus with mild gliosis in adjacent brain parenchyma, location corresponds to the contusion injury seen in previous CT.
2.Abnormal T2 signal changes in the right frontal-parietal region probably represents gliosis changes which can be due to previous insult such as contrecoup contusion injury in this clinical context. This abnormality was not conspicuous in the initial post-trauma plain CT scans. Follow-up MRI may be considered if clinically indicated.
