Clinical Summary

10-year-old patient presented with upper airway obstructive symptoms who has undergone tonsilectomy surgery


Imaging Findings

The images demonstrate a well-circumscribed mass,mostly high on T2-weighted images with small foci of signal void,arising from the posterior wall of the right maxillary sinus with partial obliteration of the maxillary sinus and nasal cavity as well as the posteriolateral displacement of pterygoid muscles,ipsilaterally.There is no evidence of surrounding edema.Inhomogeneous intense enhancement of the lesion on contrast-enhanced images is seen.On CT-scan images,intraosseous nature of the lesion with no soft tissue component is shown.Areas of thickened trabeculae surrounded with lacunae (red arrows) are depicted,suggestive of a polka-dot sign which is a clasic feature of intraosseous hemangioma.


Differential Diagnosis

1.Fibrous dysplasia,2.Intraosseous hemangioma


Final Diagnosis

Intraosseous hemangioma(proven at surgical specimens)


Discussion (Related Text)

Intraosseous hemangiomas are benign vascular anomalies of the bones. The most frequent sites of involvement are the vertebral column and the calvaria, particularly the frontal and parietal bones.
