Figure 1:(a) Brain computed tomography scan without contrast, and (b) T1 – weighted postcontrast image reveals a hyperdense to cerebrospinal fluid right frontal subdural collection with clear capsule formation, and an adjacent intraparenchymal lesion of low signal with considerable edema. (c) Fluid-attenuated inversion recovery postcontrast sequence demonstrates a densely enhancing extraaxial lesion and a well-defined ring enhancing brain lesion. (d) On diffusion-weighted image, the core of the subdural and brain lesion has typically markedly hyperintense signal (restricted diffusion)
