| lymphangioma circumscriptum | A congenital nevoid lesion consisting of a circumscribed group of tense lymph vesicles. Synonym: lupus lymphaticus, lymphangiectodes, lymphangioma capillare varicosum, lymphangioma superficium simplex. (05 Mar 2000) |
| lymphangioma, cystic | A lymphangioma, often very large, usually occurring in the neck area, and composed of large, multilocular thin-walled cysts. It is also called hygroma or cystic hygroma. (12 Dec 1998) |
| lymphangioma cysticum | A condition characterised by a fairly well circumscribed group of several or numerous, cystlike, dilated vessels or spaces lined with endothelium and filled with lymph. Synonym: cystic lymphangiectasis. (05 Mar 2000) |
| lymphangioma simplex | A circumscribed region or focus of several to numerous lymphatic vessels that are moderately dilated. Synonym: simple lymphangiectasis. (05 Mar 2000) |

| lymphangioma tuberosum multiplex | A cutaneous lesion characterised by multiple, slightly red, cystlike nodules (located chiefly on the trunk), resulting from fairly large lymphatic vessels and spaces, and groups of proliferating endothelial cells; the lesion has some gross resemblance to spiradenoma, except for the characteristic location. (05 Mar 2000) |
| lymphangioma xanthelasmoideum | A capillary lymphangioma with colloid degeneration of the elastic tissues of the skin, characterised by yellow-brown or gray-brown plaques that may be only slightly raised above the surface of the skin. (05 Mar 2000) |
| carotid-cavernous fistula | A fistulous communication, of spontaneous or traumatic origin, between the cavernous sinus and the traversing internal carotid artery; a pulsating unilateral exophthalmos and a detectable cranial bruit are common manifestations. (05 Mar 2000) |
| carotid-cavernous sinus fistula | <radiology> Aetiology: laceration of ICA within cavernous sinus; usually secondary to basal skull fractures or penetrating trauma, rupture of an intracavernous ICA aneurysm symptoms: chemosis, conjunctival oedema, bruit findings: focal or diffuse enlargement of cavernous sinus, edematous extraocular muscles, arterial enlargement (pulsating exophthalamus), dilation of superior ophthalmic, facial, and internal jugular veins, occasional sellar erosion/enlargement, enlargement of superior orbital fissure (chronic phase) (12 Dec 1998) |
| cavernous | Relating to a cavern or a cavity; containing many cavities. (05 Mar 2000) |
| cavernous angioma | Vascular malformation composed of sinusoidal vessels without a large feeding artery; can be multiple, especially if inherited as an autosomal dominant trait. Synonym: nevus cavernosus. (05 Mar 2000) |
| cavernous arteries | <anatomy, artery> A number of small branches of the cavernous part of the internal carotid artery. See: ganglionic branch of internal carotid artery, basal tentorial branch of internal carotid artery, marginal tentorial branch of internal carotid artery. Synonym: ramus sinus cavernosi arteriae carotidis arteriae, cavernous arteries. (05 Mar 2000) |
