Bone hemangiomas. Case 1 (a–c): CT (a), T1WI (b), and T2WI (c) show well-defined lytic lesion, with thickened cortical and medullar trabecular spaces (arrows in a), and internal T1 and T2 hyperintense signal corresponding to fat and vascular tissue (arrows in b and c). Case 2 (d, e): CT (d) and T1WI (e) show marked bone expansion, fat content (dashed arrows), and strikingly enlarged trabecula producing a “spoke-wheel” appearance. Case 3 (f): CT depicts interruption of outer cortical table with overcoming enlarged spiculated trabecula simulating aggressive periosteal reaction (arrowhead)
