case_images: Cranial MR showing a solid epidural 2 x 2.8 x 5 cm mass, originating from the bone, in the right parietal region with (a) homogeneously low signal intensity on T1-weighted images and (b) homogeneously high signal intensity on T2 and FLAIR images. (c-e) A 6.2 x 3.2 x 1.3 cm mass, infiltrating the bone, with similar structure and contrast enhancement is seen in mainly the left frontal area.

case_images: MR showed a solid epidural of 2 x 2.8 x 5 cm mass, originating from the bone, in the right parietal region, showing homogeneously low signal intensity on T1-weighted images (Figure 2(a)) and homogeneously high signal intensity on T2 and FLAIR images (Figure 2(b)), with an intense contrast enhancement (mainly) in the peripheral zone and smaller necrotic areas in the central zone. Moderate oedema around the mass is present, with higher apparent diffusion coefficient (ADC) value on the ADC images. A 6.2 x 3.2 x 1.3 cm mass, infiltrating the bone, with similar structure and contrast enhancement is seen in mainly the left frontal area (Figures 2(c)-2(e)).
