Summary:

Description	Radiopaedia case ID: 49234 Image ID: 26336435 Image stack position: 17/20 Plane projection: Axial Aux modality: non-contrast Study description: Post operative study Study findings: There is complete resolution of the previously seen soft tissue attenuation focus involving the inferolateral extraconal space and zygomaticus and distal temporalis muscle. The bony orbital floor and lateral zygoma shows changes of remodeling. Residual aneurysmal bone cyst persists. N.B. intraoperatively, only blood was aspirated. Modality: CT System: Musculoskeletal Findings: There is a well defined expansile cystic lesion with fluid fluid level noted to involve superolateral maxillary bone and zygoma. Features favor aneurysmal bone cyst. There is secondary breach of the outer table of zygoma with resultant subtle hypodensities within the proximal zygomaticus and distal temporalis muscle. Also seen is breach of the left sided bony orbital floor with extension of hypodensities into the inferolateral extraconal space. Resultant indentation of the globe inferiorly with loss of fat planes between inferior and lateral rectus muscle noted. Right orbit shows normal imaging features.
