 There is no evidence of acute ischemic or hemorrhagic lesion on this scan.There is no evidence of hippocampal sclerosis on this scan.There is however, about 3mm sized fluid, likely CSF, filled space at the junction of subiculum and CA1. The lesion appears to be in continuum of hippocampal fissure.Underlying brain shows scattered of high signal intensity lesions on bilateral hemispheres and periventricualr white matter indicating non specific small vessel disease.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No MR evidence of hippocampal sclerosis or abnormal enhancement. However, if clinically indicated dedicated temporal lobe MRI can be considered since it will provide much precise and detailed evaluation for temporal lobe imaging analysis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
