Presentation
Child with a painful left forearm.
Patient Data
Expansile mass in the mid-diaphysis of the radius. Loss of cortex and aggressive appearances.
Increase uptake in the blood pool as well as delayed images.
The expansile mid-radial mass contains multiple septa and fluid-fluid levels. Fluid-fluid levels are seen in ABC and telangiectatic osteosarcoma.
The forearm following resection and grafting.
Case Discussion
X-rays of the forearm of a child demonstrate an expansile bubbly lesion of the mid radial diaphysis, with irregular margins, no convincing matrix mineralization and no convincing soft tissue extra-osseous mass.
Bone scans demonstrate increased uptake.
MRI elegantly demonstrates multiple fluid-fluid levels, which although non specific suggest the diagnosis of an aneurysmal bone cyst (ABC). This was confirmed on histology following resection and grafting.
