T1-weighted images revealed a left retrocerebellar epidural hypointense collection with dural contrast enhancement [Figure 1a]. T2-weighted and diffusion-weighted imaging showed the collection as a high-intensity area [Figure 1b and c]. Magnetic resonance venography revealed left lateral-sinus thrombosis [Figure 1d].
