Female, 23 years old, with seizures. Encephalomalacia and cystic degeneration is seen along the left parahippocampal gyrus and a portion of the inferior temporal gyrus. The amygdala and the hippocampal formation proper are relatively unaffected. The forniceal columns and mammillary bodies are of symmetric caliber bilaterally.Elsewhere brain parenchymal morphology is unremarkable. No additional focal signal abnormality, edema, or structural anomaly is seen. No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles are normal in size and morphology.
1.Encephalomalacia and cystic degeneration affecting the left parahippocampal gyrus and left inferior temporal gyrus are unchanged. These findings may reflect the sequelae of prior infection or inflammation.2.The remainder of the brain is unremarkable.
