[Intraosseous cavernous haemangioma of the bony orbit]

Primary orbital intraosseous haemangioma represents a rare, histopathologically benign, vascular tumour of the bony orbit. Only 46 cases have been documented to date. The most frequent presentation is a painless mass on the orbital rim. This condition often affects patients in their fourth and fifth decades of life. More women than men are affected. Histopathologically, the lesions are cavernous, capillary or mixed. The cavernous subtype is the most common one. Surgery can be complicated by life-threatening haemorrhage. The authors present a new case.
