Complex febrile convulsions [R56.01], Reason for Study: ^Reason: rule out brain structural abnormality History: seizure There are a couple of small (less than 2mm) T2 high and T1 low signal intensity lesions on the right hippocampal head which follow the signal intensity of CSF. There is no MR evidence of focal parenchymal signal abnormality of the hippocampus nor evidence of volume loss. Constellation of above findings suggest possible hippocampal sulcus cysts. The left side hippocampus appears to be normal.There is no evidence of acute ischemic or hemorrhagic lesion on this scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. 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. Hippocampal sulcus cysts on the right hippocampal head, otherwise no remarkable finding.
