NIMG-43. INFARCTION RADIOLOGICALLY MIMICKING INTRA-AXIAL BRAIN TUMORS

Abstract There are several reports of brain lesions that radiologically mimicking the brain tumors. The abscess is representative lesion of resembling the intra-axial tumors in brain MRI. However, cerebral infarction is not a common lesion that resembles a brain tumor and can be easily distinguished from a brain tumor in MRI. Here, we represented the two cases of pathologically diagnosed infarction that radiologically suspected gliomas. A 67-year-old man presented with left side weakness and memory impairment. Brain MRI revealed the rim enhancing lesion radiologically suspected glioma. Navigation guided biopsy was performed and final pathological diagnosis was subacute infarction. A-41-year-old man represented the right side weakness. MRI showed the enhancing nodular lesion with perilesional edema. Surgical excision was performed and pathological diagnosis was infarction. Although advancement of brain imaging techniques, it is difficult to accurately discriminate the intracerebral lesions utilizing the MRI. Further comprehensive study should be executed for more precise differentiation of infarction and brain tumors.
