Subacute cerebral infarction - with MR spectroscopy

Discussion:

Conventional MRI sequences suggest infarction, cerebritis versus low grade glioma. DWI and ADC are not conclusive because the scan was done on the subacute stage when re-perfusion masked diffusion restriction effect. MRS is more conclusive as there is mild reduction of NAA consistent with neuronal damage and marked elevation of lactate indicative of anerobic metabolism. The non rise of Cho peak excludes neoplastic activity.
