cavernous haemangioma

Also found in: Dictionary, Thesaurus, Encyclopedia.

haemangioma, cavernous

A benign orbital tumour in adults, mostly females. The tumour is composed of large blood-filled spaces possibly due to dilatation and thickening of the capillary loops. The most common site is the muscle cone behind the globe causing proptosis, hyperopia and choroidal folds. Visual acuity may be reduced. Treatment is surgical in most cases.
