Postictal edema. A 60-year-old woman with stage 4 bronchial carcinoma was admitted to the ER because of generalized epileptic seizures. Contrast-enhanced axial T1 (a) showed a contrast-enhancing mass lesion with extensive perilesional oedema in the left parietal lobe, corresponding to a brain metastasis. An axial T2 image (b) shows increased signal intensity in the left hippocampus and amygdala. Diffusion-weighted images (c) with an ADC map (d) show restricted diffusion laterally in the left hippocampus
