DC with bone remodelling in a 14-year-old male with lateral supraorbital soft tissue swelling and induration. a Axial CT (bone window) shows well-demarcated cystic subcutaneous lesion (arrowhead) with frontal bone scalloping and no cortical erosion (arrow). b Three-dimensional CT VR reconstruction shows bone remodelling in the supraorbital left area (arrow). c DWI reveals high signal on the b = 1000 image (arrowhead, upper image part) and high signal on the ADC map (arrowhead, lower image part, ADC = 2.5 × 10−3 mm2/s), compatible with no restricted diffusion and characteristic of a DC. d Peripheral lipid density on T2 (arrow, upper image part) and T1 with low signal (arrow in e) in gadolinium-enhanced coronal fat-saturated T1. Central soft tissue density on T1 (arrowhead in lower image part) with no contrast enhancement (arrowhead in e), corresponding to squamous debris
