"Usually presents as an expansile bone lesion with thin borders and a characteristic sunburst pattern of trabecular thickening radiating from a common centre 7. Erosions of both internal or external plates can occur and may be associated with internal or external tumour expansion. Sometimes, bony trabeculae can grow beyond the cortical bone, and simulate an aggressive pseudo-"hair-on-end" periosteal reaction 4."
"T1: typically hyperintense, though atypical T1 hypointense forms are not rare"
"T2/FLAIR: hyperintense signal with a "bunch of grapes" appearance 7"
"T1 C+ (Gd): homogeneous enhancement is often present"
