Neuroimaging features of IAE. Case 3: (A) T1-weighted imaging shows a slightly higher signal mass. (B) T2-weighted imaging reveals a heterogeneous low signal mass with peripheral high signal intensity, suggesting edema. (C) Fluid-attenuated inversion recovery imaging (FLAIR) reveals a heterogeneous low signal mass. (D) Postcontrast axial T1-weighted imaging shows cauliflower peripheral gadolinium-contrast enhancement at the lesions. (E–H) Right lateral ventricular dilatation and hydrocephalus occurred 7 months after right parietal and occipital lobe resection.
