Subperiosteal haematoma of the iliac bone

Case contributed by Dr Salem Bauones


Incidental finding.

Patient Data

Age: 20
Gender: Male

Unenhanced CT images show an ossified lens-shaped lesion of the right iliac bone on its medial aspect. It represents the subacute phase of sub-periosteal haematoma with ossified periosteum on the sides of the haematoma (lytic lesion) and preserved iliac cortex which is called "ghost native cortex".

MR images show lens-shaped lesion of the medial aspect of right iliac bone, presenting fluid signal intensity (hypointense on T1W and hyperintense on T2W). Note the smooth edge of the periosteal ossification which presents the same signal intensity as the iliac bone and shifts the iliacus muscle medially.

Case Discussion

Findings are suggestive of subperiosteal haematoma of the iliac bone.
