Orbital Capillary Haemangioma

orbital haemangioma

This 2 month-old male patient presented with downward displacement of the right globe. This axial contrast-enhanced CT demonstrates a homogeneous-density mass with a lobulated contour, and a prominent associated vessel.

Capillary haemangioma of the orbit is the most common orbital tumour of infancy. It is a benign neoplasm and should be differentiated from cavernous haemangioma, a non-neoplastic vascular malformation. Capillary haemangioma may involve any area of the orbit, from preseptal space to retrobulbar, and may be intra- or extraconal. They typically grow rapidly in the first year, then involute slowly.

The CT appearance is that of a strongly enhancing lobulated mass. The enhancement is typically homegeneous. The differential diagnosis includes lymphangioma, rhabdomyosarcoma, neuroblastoma, or chloroma. Management is conservative unless there are complications such as marked proptosis, in which case corticosteroid treatment is usually effective.
