Intraosseous haemangioma and fibrous dysplasia of the maxillary bone

Case contributed by Dr Salem Bauones


Left maxillary small painless lump.

Patient Data

Age: 45
Gender: Male

Axial and coronal CT images of paranasal sinuses demonstrate:

  • Right anterior maxillary bone: small expansile lesion with homogeneous ground glass appearance.
  • Left anterior maxillary bone: small expansile lesion with thickened vertical trabeculation giving the "polka-dot appearance".

The green arrow marks the focal fibrous dysplasia of the right maxillary sinus. The intraosseous haemangioma of the left maxillary sinus is indicated by the yellow arrow.

Case Discussion

This case demonstrates right anterior maxillary fibrous dysplasia and left anterior maxillary intraosseous haemangioma. Both are benign common disease of the bone, especially the skull 3. The polka-dot sign is a classic feature of intraosseous haemangioma caused by the thickened trabeculae surrounded by vascular lacunae.
